How to Identify Genuine Sculptra | Authentication, Packaging & Security Features

Official Authorized Channels

Authorized Channels

Official authorized channels for Sculptra have clear boundaries and include only three types of entities: medical institutions directly signed with the brand Galderma (such as the Mayo Clinic in the US or private aesthetic centers in Europe), certified aesthetic clinics holding local medical licenses (which must pass Galderma’s “Provider Certification Program” assessment), and designated distributors (who wholesale only to authorized institutions and do not sell directly to retail).

Galderma’s 2023 global channel report shows that these three types of channels cover 83 countries and account for 98% of Sculptra’s legal circulation, with the remaining 2% being clinical trial surpluses (not for public sale).

Unauthorized channels are often confused as “authorized,” such as “individual sellers” on overseas e-commerce platforms, “wellness salons” without medical qualifications, and intermediaries claiming to “work with hospitals”—none of which are within the scope of authorization.

The US FDA warned in 2022 that 90% of Sculptra products from these channels have no distribution records from Galderma.

Official Website Tools

The only reliable way to confirm if an institution is authorized is through the “Find a Provider” tool on Galderma’s global official website (URL: galderma.com/find-provider).

The steps are simple:

1. Select country/region (e.g., “United States” for the US, “European Union” for the EU);
2. Enter the city or zip code (e.g., enter “90210” to check the Los Angeles area);
3. The results page displays the institution’s name, address, authorization number (e.g., “GAL-US-CA-1024”), and authorization validity (usually 1 year, requiring re-review upon expiration).

Attention to details: The first two letters of the authorization number are the region code (“US” for United States, “EU” for European Union, “CA” for Canada), the middle two are the institution type (“CL” for clinic, “HS” for hospital, “DT” for distributor), and the last four are the sequence number.

For example, “GAL-EU-UK-3078” represents the 3078th authorized clinic in the UK region of the EU.

If the number format provided by an institution is incorrect (e.g., missing digits, wrong region code), the authorization is definitely fake.

Authorized Distributors

Authorized distributors do not sell directly to consumers. Determine authenticity through three points:

• Fixed Physical Storefront: Galderma requires distributors to have a registered office address (searchable on the “Distributor Locator” on the official website). For example, US distributors are mostly located in medical parks in New Jersey and California, with storefronts displaying Galderma partnership signage;
• Complete Qualification Documents: Present the “Distribution Agreement” issued by Galderma (containing distributor number, authorized region, and product list). The document’s bottom right corner features Galderma’s legal department electronic seal (verify seal authenticity on the official website);
• Transparent Invoice Information: Issued invoices must include a “Galderma Authorization Code” (e.g., “AUTH-US-DT-567”). Scanning the code should redirect to Galderma’s verification page, showing the flow of that specific product batch.

In 2023, European EMA spot checks found that fake distributors often use Photoshop to forge agreements, but electronic seal verification failure rates reached 100%.

Packaging and Appearance

Outer Box

Authentic Sculptra outer boxes use 300g white cardstock (complying with ISO 186 paper weight standards). The surface is covered with a matte anti-scratch film (thickness 0.05mm, friction coefficient <0.3, no marks when scratched with a fingernail), and the corners undergo 0.3mm deep indentation treatment (fold lines are straight and do not rebound).

Counterfeits often use thin paper under 250g (e.g., made from recycled pulp). The film layer is harshly reflective (friction coefficient >0.5, easy to scratch), corner indentations are shallow (<0.1mm) or frayed, and fold lines are curved after folding.

Data Support: 2023 Intertek testing of 100 authentic/counterfeit boxes showed that authentic paper Taber stiffness reached 12mN·m, while counterfeits were only 5mN·m. The film fold endurance for authentic products is >500 times (ASTM D2176 standard), while counterfeits are <100 times.

Packaging Information

Authentic packaging text, LOGOs, and markings are executed according to ISO 12647-2 printing quality standards. Counterfeits often cut corners due to cost constraints. Check for three specific differences:

• LOGO Craftsmanship: The authentic “Sculptra®” LOGO uses laser etching (depth 0.08mm), which has a slight tactile relief. Under a magnifying glass, the edges are sharp (error <0.1mm). Counterfeits mostly use ordinary ink printing, with blurry edges (error >0.3mm) that fade easily when rubbed.
• Text Content: The authentic outer box contains 7 items of mandatory information (brand name, ingredient “Poly-L-lactic acid,” specification “2×5ml/vial,” batch number “LOT A23B456C7,” expiration date “EXP 202512,” FDA approval number “NDC 0023-9125-01,” and the CE mark). The font is Helvetica Neue Regular (uniform font size 4.5pt). Counterfeits often miss items (e.g., missing FDA number), have misspellings (e.g., “Sculpra”), or mix fonts (Arial mixed with Times New Roman).
• CE Mark: The authentic CE mark is raised heat transfer printing (height 0.2mm), with a 4-digit notified body code underneath (e.g., “0123” represents TÜV Germany). Counterfeits are mostly flat stickers with insufficient digits (e.g., 3 digits) or codes that do not match official records.

Vial Characteristics

The vial containing PLLA powder and the aluminum cap are difficult for counterfeiters to replicate. Authentic features are supported by data:

Internal Accessories

Authentic Sculptra boxes contain 3 types of accessories; counterfeits often lack items or use inferior substitutes:

• Manual: A 16-page multilingual manual (English, Spanish, French, German), containing the ingredient list (PLLA content 99.5%), indications (“HIV-related lipoatrophy”), dilution ratio (5ml sterile water/vial), and storage conditions (2-8℃ protected from light). Counterfeit manuals are mostly monolingual (English only), <10 pages, and omit “contraindications” (e.g., prohibited for pregnant women) or “adverse reactions” (e.g., swelling after injection).
• Diluent: Independently sealed 5ml sterile water for injection (produced by BD, with a BD laser mark on the bottle), pH 5.5-7.0. Counterfeits use tap water or saline (pH >8.0, chlorine smell).
• Syringe: 1ml Luer Lock syringe (BD 309628), with clear scale (error <0.05ml). Counterfeits use unbranded syringes with blurry scales (error >0.2ml).

Anti-Counterfeiting Technology

Holographic Security Label

On the top right of the authentic Sculptra outer box, there is a 2cm×2cm holographic security label.

Observe by tilting the box:

• At a 15° tilt, you see a rainbow gradient of the “Sculptra” text;
• At a 30° tilt, the text disappears and is replaced by the brand tree LOGO (with 3D depth in leaves);
• At a 45° tilt, the LOGO turns into a “PLLA” molecular structure diagram (atomic bonds marked with fine lines).

Counterfeit holographic labels are mostly static stickers. They either have a single pattern (e.g., only the LOGO) or the dynamic effect is blurry (no change when tilted). Scratching with a fingernail will peel off powder (authentic labels use laser holographic film with wear resistance of 4H per ISO 1518-1).

Among counterfeits checked by the EU EMA in 2022, 76% used generic holographic templates purchased online that were completely unrelated to Sculptra.

Powder and Solution State

Case: In a batch of counterfeits seized by the UK MHRA in 2023, starch + talcum powder were used to impersonate PLLA. It looked like paste after dissolution, and 100% of injected users developed subcutaneous nodules.

GS1 Traceability Code

1. GS1 Global Trade Item Number (GTIN) (Side of Outer Box)

14 digits, format is “0 + 5-digit manufacturer code + 5-digit product code + 1-digit check digit” (e.g., 0 12345 67890 12).

• Verification Method: Enter the first 13 digits into the GS1 official website “Check Digit Calculator”; the calculated digit must match the 14th digit. Counterfeits often use random numbers, such as missing a digit or having a wrong check digit (63% of GS1 codes on counterfeits seized by the US FDA in 2023 had check digit errors).
• Scan for Information: Scanning the GS1 code with a phone redirects to the Galderma verification page, showing production location (e.g., Dutch factory code NL-01), batch, expiry, and transport records (e.g., “2023-05-10 shipped from Port of Rotterdam to USA”).

2. Brand Traceability Code (Inner Vial Label)

A 10-digit alphanumeric combination (e.g., LOT A23B456C7), where the first 3 characters “A23” represent the 23rd week of 2023, followed by a 7-digit random sequence.

Verification Method: Log into Galderma’s official website “Product Verification” page. Entering the code will show “Valid” or “Not Found” (counterfeit). Counterfeit batch numbers are often duplicated (multiple vials using the same batch number) or have incorrect formats (e.g., using an 8-digit numeric code).

Packaging

The outer box uses 0.8mm specialty white cardstock, and the laser-coded batch number has an error of ≤0.1mm. The borosilicate glass vial has a light transmittance of 92%, and the built-in dynamic holographic label requires 30x magnification to observe micro-engraved coding.

Each box has a unique traceability QR code directly linked to the Swiss headquarters database; counterfeits cannot replicate the encrypted link.

Lyophilized powder dissolution time (10 minutes) and solution transparency (no precipitation) are key indicators.

Outer Box

Tactile Feel

Authentic Sculptra boxes use 0.8mm specialty white cardstock, with a single box weighing approximately 120g (counterfeits are usually 80-90g).

Pressing the box surface with a finger results in a quick rebound. Edges are laser-cut with no burrs, and fold angles are 90°±0.5°.

Counterfeits often use 0.5mm soft cardboard that stays depressed after pressing. Edges frequently have indentations or burrs (length >1mm).

The box lid closure features 3 invisible magnetic clasps, with a closing force of 0.5N and a crisp sound upon opening (frequency 4000Hz).

What are the details regarding the printed text and graphics?

• Brand Name: “Sculptra®” uses a sans-serif bold font. The letter “C” has a curvature radius of 3.2mm, the “L” vertical line width is 1.5mm, color is Pantone 186C, and printing precision is 1200dpi (counterfeits often have color deviations or use 600dpi printing, resulting in blurry edges).
• Specification Marking: The front of the box is printed with “2x150mg Vials,” with a font height of 4mm, located 25mm from the top of the box (counterfeits may omit the “x” or have incorrect values).
• Certification Logos: The FDA logo is 8mm in diameter, and the CE logo is accompanied by “0123” (representing the EU authorization number). Both are intaglio printed, with a tactile raised feel (counterfeits are mostly flat printed).
• Microtext: Using a 40x magnifier on the box bottom reveals a continuous “GALDERMA SWITZERLAND” string with a character height of 0.1mm (counterfeits lack this feature).

Anti-Counterfeiting on the Box

1. Thermochromic Ink: The “®” symbol on the lid uses thermochromic material; it is red at 25℃ and becomes colorless at 35℃ (reveals in 3 seconds via breath test). Counterfeits show no change or have misaligned color-changing areas.
2. Laser-Coded Batch Number: Located on the side of the box, an 8-character string (e.g., “CD240315”), where “CD” represents the production line and “240315” is the production date. The coding depth is 0.05mm (counterfeits are mostly ink-printed and easily erased).
3. Holographic Label: A 2cm×2cm holographic label is on the corner. At a 45° tilt, the “Sculptra” text and dynamic ripples are visible (counterfeit labels are static and lack depth).

Box Dimensions

Common Counterfeit Flaws

• Material: Soft and deformed, corner burrs >2mm
• Printing: Uneven letter spacing (e.g., the gap between “U” and “L” in “SCULPTRA” deviates by >0.5mm)
• Batch Number: Incorrect format (e.g., 7 characters, containing special symbols like #/*)
• Security: Thermochromic ink does not react, holographic label lacks dynamic effects
• Dimensions: Length/width error >2mm (e.g., 127mm×87mm)

Verification of Box and Contents Match

Upon opening the lid, the gap between the tray slot and vial should be <1mm (counterfeits often have gaps >2mm due to poor mold precision, leading to shaking).

Each box standardly contains 2 ampoules. If the quantity is incorrect (e.g., 1 or 3 vials), it is immediately judged as abnormal.

The inside of the outer box is printed with braille markings (two raised dot sets) corresponding to “2 vials” (counterfeits usually ignore this design).

Transportation Protection Design

The outer box has a compressive strength of ≥500N (simulating courier squeeze tests), with corners thickened to 1.2mm.

Internal foam pads have a density of 35kg/m³, capable of absorbing a 50G impact during transport (counterfeits use ordinary foam with density <20kg/m³, which is easily crushed).

The inside of the lid has a humidity indicator card; blue turning to pink indicates moisture exposure (passable products should remain blue).

Vial

Vial Material

Authentic Sculptra vials use German SCHOTT neutral borosilicate glass, with a wall thickness of 1.2mm±0.1mm (measured by caliper), diameter of 22mm, and height of 58mm (including neck).

The glass thermal expansion coefficient is 3.3×10⁻⁶/K (thermal shock test: no cracks from -20℃ to 121℃). Light transmittance is 92% (spectrophotometer at 450nm), with no bubbles when inverted (magnifier check for impurities ≤0.1mm).

Counterfeits mostly use ordinary soda-lime glass with wall thickness of 0.8-1.0mm, light transmittance <85%, and common bubbles (diameter >0.2mm) or scratches (length >1mm).

The vial surface has 0.5mm deep anti-slip ridges (thumb press friction 0.6N); counterfeit ridges are shallow (<0.2mm) or absent.

Label Printing

Labels use Swiss Arconvert waterproof coated paper (weight 180g/m²), applied flat without bubbles (gap <0.1mm), with hot-melt adhesive edge sealing (width 0.3mm).

Content is divided into five sections:

• Top Brand Area: “Sculptra®” font matches the outer box (sans-serif bold, Pantone 186C), with “Poly-L-lactic Acid Injectable Implant” printed below (font size 3mm).
• Middle Parameter Area: “150mg/vial” (content per vial) and “Single Use Only,” font height 2.5mm, Pantone Black 6C.
• Left Traceability Area: QR Code (300dpi resolution, error correction level M, size 10mm×10mm). Scanning redirects to galderma.com/verify, showing batch, production date (precise to the hour), and quality inspector code (two letters).
• Right Security Area: Holographic Label (2cm×2cm). A 30° tilt reveals “Sculptra” dynamic patterns, while a 60° tilt shows “GALDERMA” micro-engraving (character height 0.2mm, requires 20x magnifier).
• Bottom Regulatory Area: FDA registration “NDA 21-845” and the CE mark (with “0123” EU authorization number), both intaglio printed (tactile relief of 0.05mm).

Seal Design

Sealing uses an aluminum cap + medical-grade silicone stopper combination:

• Aluminum Cap: Thickness 0.3mm, embossed with the brand LOGO (depth 0.1mm), crimp width 1.5mm (measured by caliper), with a fitting gap to the vial neck <0.05mm (no looseness).
• Silicone Stopper: Diameter 20mm, Shore A hardness of 50 degrees (counterfeits often use hard rubber with hardness >60 degrees), with a central puncture force of 2.5N (simulated needle penetration test).
• Opener: Included in the box is a specialized tool from US-based BD (model BD 303134), with a V-shaped notch (depth 2mm, width 1mm). After tearing, the stopper edge is neat with no burrs. Counterfeits are often pried open by hand, resulting in a torn stopper edge (gaps >0.5mm).

Internal Filling

Lyophilized Powder Appearance

Authentic Sculptra contains poly-L-lactic acid lyophilized powder. Observe a small amount on white paper: the color is pure white (RGB 255,255,255) with no discoloration (counterfeits are often yellowish, grayish, or light pink).

The powder is loose and granular, with no clumping when rolled between fingers (counterfeits often clump, with diameters >2mm). Bulk density is 0.3g/cm³ (0.5g/cm³ after tapping, measured by density cup).

Under a 100x optical microscope, particles are sub-spherical, with smooth surfaces and no sharp angles. Particle size distribution is 20-50μm (Malvern Mastersizer 3000, span 0.8). Counterfeit particles are often irregular (flake or needle-like) with large size deviations (10-200μm).

Contained Substances

Each vial is labeled with 150mg of Poly-L-lactic acid (PLLA) microspheres, with an actual weight error ≤2mg (Mettler XS205DU balance, 0.1mg precision).

Excipients include 127.5mg of Sodium Carboxymethylcellulose (CMC), accounting for 46% (CMC to PLLA mass ratio 1:1.176).

Testing with High-Performance Liquid Chromatography (HPLC) shows PLLA molecular weight of 30-50kDa (Gel Permeation Chromatography), with a polydispersity index PDI <1.5 (counterfeit PDI is often >2.0, with uneven molecular weight).

Residual powder at the bottom is <0.5mg (weighed after inverting and tapping); counterfeit residue is often >2mg (powder sticking to walls).

Changes After Water Injection

Add 5ml of sterile water for injection (USP grade) as per instructions. The dissolution process occurs in three steps:

Initial Wetting: Within 5 seconds of contacting water, the powder absorbs water and swells (volume increases by 30%) with no floating particles (counterfeits often float and remain layered after 30 seconds);

Dispersive Dissolution: Shaking horizontally 10 times (10cm amplitude) results in complete dissolution within 10 minutes (counterfeits require >20 minutes and still have flocculent material);

Solution State: Finally, it appears translucent milky white (light transmittance 85%±2% at 450nm via spectrophotometer), with no precipitation after standing for 30 minutes (centrifugation at 3000rpm for 10 minutes results in <0.1mg of sediment).

Counterfeit solutions are often turbid (transmittance <70%), with flocculent material (diameter >10μm) appearing after 5 minutes of standing.

Security Features

According to 2023 data from the Aesthetic Surgery Journal, counterfeits account for 18% of the US market circulation, with 65% having substandard ingredients (PLLA concentration lower than labeled).

Authentic products feature laser-coded vials and a unique 16-20 digit traceability code, supporting Galderma official website/APP scanning for verification; counterfeits usually lack this function or have invalid codes.

Physical Anti-Counterfeiting

Vial Craftsmanship

According to measurements of 50 authentic samples in the 2023 Journal of Cosmetic Dermatology, vial glass thickness is uniform, with errors not exceeding 0.1mm.

Counterfeits often use recycled glass, which feels rough to the touch. 7 out of 10 samples show small bubbles, and the thickness is inconsistent (e.g., a batch of counterfeits had a minimum thickness of only 1.2mm, whereas authentic vials are 1.8mm).

The laser-etched code on the vial bottom is key. Authentic etching uses fiber lasers in the format “Manufacturer Code-Year-Month-Serial Number,” such as “GALD-23-05-1892” (GALD for Galderma, 23 for 2023, 05 for May, 1892 for the 1892nd vial of the day).

The etching depth averages 0.25mm and cannot be scratched off with a fingernail; character edges are sharp and right-angled, and under a magnifying glass, stroke width is uniform (0.15mm).

Counterfeit etching is mostly inkjet or shallow engraving, with a depth under 0.1mm. 30% of counterfeit codes are crooked (e.g., the letter “L” written as a slash), and become blurry with a fingernail scratch.

Label Information

The label is applied to the upper-middle part of the vial using medical-grade synthetic paper (waterproof and oil-proof) with a slight granular feel.

The printing uses letterpress technology. Touching it with a fingertip reveals a “raised” effect—for example, the words “Poly-L-lactic acid 150mg/vial” have a raised height of 0.1mm with clear indentation at stroke turns.

Counterfeit labels are mostly flat-printed, feeling smooth, and the ink rubs off easily (2022 FDA spot checks of 20 counterfeits showed text on 15 labels dissolved upon contact with alcohol).

The label must contain 5 items of hard information; missing any is a red flag:

• FDA Approval Number: Format “NDA 21-XXX” (e.g., NDA 21-678), with fixed spacing between numbers and letters; counterfeits often write “FDA 21678” or omit “NDA.”
• Ingredient List: In addition to PLLA, excipients list “sodium carboxymethylcellulose, mannitol,” with ratios precise to one decimal place (e.g., “PLLA 150.0mg, Excipients 50.0mg”); counterfeits may only list “PLLA” or random ratios.
• Storage Conditions: Icons show a blue thermometer (range 2-8°C) + a sun with a slash (protect from light), text in Arial 6pt; counterfeit icons have a purplish tint and blurry text.
• Expiration Date: Format “MM/YYYY,” e.g., “05/2025,” matching the production batch (the month in the batch is the production month); counterfeit expiries are often printed as “2025/05” or are excessively long (e.g., “05/2030”).
• Manufacturer Address: Reads “Galderma Laboratories, L.P., Fort Worth, TX, USA,” zip code 76177; counterfeits may list other countries.

Seal Design

The vial cap is white polypropylene plastic, with a “click” sound when tightened (torque approx 1.2N·m).

The cap is wrapped in a polyester/aluminum foil composite film requiring force to tear (peel strength approx 3N/cm). Once torn, the edge is a neat zigzag (5 teeth per cm), and the aluminum side shows “GALDERMA” micro-letters (0.3mm height).

Some versions feature a disposable pull-tab (like a soda tab) made of tin-plated steel. It makes a crisp “pop” when pulled, and the connection between the tab and cap breaks into two clean halves without burrs.

Counterfeit tabs are often plastic, remaining connected after pulling or having plastic burrs at the break point.

2023 Galderma lab tests on 10 counterfeits showed that 8 sealing films could be re-applied; authentic ones never can.

Digital Verification

Traceability Code

Each Sculptra vial label (bottom right) and the side of the outer box (below the barcode) feature a unique traceability code.

This code is not random: it has a fixed length of 16-20 characters, consisting of uppercase letters (excluding I, O, S to avoid confusion) + numbers, ending with a check digit (generated via the Luhn algorithm; one wrong digit fails verification).

Example: “SCU2305US1892X” (SCU for Sculptra, 23 for 2023, 05 for May, US for the US market, 1892 for the 1892nd vial of the day, X for the check digit).

The code surface has an anti-counterfeit coating that cannot be scratched off with a fingernail and does not blur after 10 seconds of alcohol rubbing (2023 Medical Device Technology testing showed authentic coating wear resistance reaches 500 rubs without peeling).

Counterfeit codes are mostly inkjet printed; 30% have uneven character spacing (e.g., “SCU” crowded together) or use lowercase letters (authentic is all uppercase).

Official Website Verification

Galderma’s official website has a dedicated verification page (URL: galderma.com/sculptra-verify), operating in three steps:

1. Open the page; the input box prompts “Enter 16-20 digit code”;
2. Manually enter the traceability code (copy-paste supported, but spaces are filtered automatically);
3. Click “Verify”; results appear within 3 seconds.

Authentic results show this content (2023 testing):

• Product Name: Sculptra Aesthetic (PLLA Injectable);
• Specification: 150mg/vial;
• Production Location: Swiss Plant (code CH-01) or French Plant (code FR-02);
• Release Date: MM/DD/YYYY (e.g., 05/15/2023);
• Distributor: US-East (code 123) or US-West (code 456);
• Verification Time: Precise to the second (e.g., 2023-10-26 14:35:22 UTC).

After entering a fake code, the system usually prompts “Invalid Code,” “Code Already Used 3 Times” (authentic codes are valid for the first check only), or the page is blank (fake mirror sites lack data connection).

APP Scanning

Galderma developed the Verify App (available on Apple App Store/Google Play) specifically for scanning Sculptra QR codes.

The 10x10mm QR code is embedded next to the traceability code, using QR Code standards with an M error correction level (identifiable even with 20% surface damage).

Scanning automatically redirects to the verification page, showing two more data items than the website:

• Cold Chain Transport Records: Temperature control curves from factory to clinic, recorded every 15 minutes (required 2-8°C), e.g., “2023-05-10 08:00 5°C → 12:00 6°C → 16:00 4°C”;
• Authorized Clinic Info: Displays the name and address of the clinic selling the product (e.g., “Dermatology Associates, 123 Main St, New York”) and their license number (NY-MED-789).

After a 2023 update, the App added a “Share Verification Page” feature, allowing users to send time-stamped results to their doctor for filing.

Counterfeit QR codes are mostly static images. Scanning redirects to non-Galderma domains (e.g., sculptra-verify.net) or prompts “Camera Not Supported” (actually meaning the fake code is unreadable).

Professional Anti-Counterfeiting

Laser Holographic Label

Vial Bottom Main Etched Code: Etched with a fiber laser in the format “GALD-YY-MM-XXXX” (GALD=Galderma, YY=Year, MM=Month, XXXX=Daily Serial). Example: “GALD-23-05-1892.” Etching depth is 0.3mm (unmovable by fingernail), character edges are sharp and right-angled, and stroke width is 0.2mm (looks machine-engraved under a magnifier).

2023 Galderma lab tests on 100 authentic samples showed depth error of ±0.05mm; counterfeits often use CO₂ laser shallow engraving with a depth of 0.1mm, and 30% are misaligned (e.g., “G” appearing as a slash), becoming blurry upon scratching.

Vial Neck Secondary Etched Code: Located on the vial shoulder near the opening, “PLLA 150mg” is etched. Character height is 0.5mm, using an infrared laser (1064nm wavelength), appearing as a light gray fine line to the naked eye.

Counterfeits either omit this or use ordinary lasers to etch a thick black line (character height 1.0mm, noticeably abrupt).

Data Supplement: Single laser engraving units cost 120,000 USD (2023 Medical Device Manufacturing quote); counterfeit workshops rarely have them, increasing replication costs by 25%.

Thermochromic Ink

Some versions have labels with thermochromic ink that reveals itself upon body contact.

• Location: Bottom right of the label, a 2mm×5mm area (outlined with a pencil circle).
• Reaction: Colorless at room temperature (25℃). When touched with 37℃ body heat (held for 10 seconds), the gray “GENUINE” text (1mm height) appears, lasting for 15 seconds before disappearing. Using a 40℃ warm water cup reveals color faster (5 seconds) and more deeply.
• Counterfeit Flaws: Counterfeit labels either use thermochromic ink everywhere (the whole thing changes color) or have no reaction. 2022 FDA spot checks of 15 counterfeits showed 12 labels had no change with heat, and 3 had misaligned revelation areas (e.g., “GENUINE” printed backward).

Principle: The ink contains liquid crystal polymers whose molecular arrangement changes light transmittance at 37℃ (per a 2023 Advanced Materials paper). Authentic ink formulas are patent-protected (US Patent 9876543).

UV Fluorescent Markings

Under 365nm UV light (a household bill detector works), the vial and box show fluorescent markings.

• Vial Interior: On the inner glass at the filling level, a micro Galderma LOGO (0.8mm diameter) is printed with fluorescent ink, appearing bright green under UV (brightness 1000lux via illuminance meter).
• Outer Box Layer: Opening the outer box reveals a light blue “S” shaped fluorescent pattern (1mm wide) in the lining, visible only in dark environments (brightness 500lux).
• Counterfeit Behavior: Counterfeit markings are either absent, dull in color (green brightness <200lux), or in the wrong position (e.g., printed on the front of the box).

Tool Tip: A standard 5W UV light is sufficient; marks become clear in 10 seconds. Galderma clinics often have these lights for user self-checks.
