Dermalax (1-2ml per side) is injected deeply into the nasolabial fold using a 27G cannula, with massaging post-injection to smooth lumps, yielding 12-18 month results; mild swelling may last 24-72 hours.

ToggleWhat is Dermalax?
Dermalax is a hyaluronic acid (HA)-based dermal filler specifically designed for nasolabial folds—the lines that run from the nose to the mouth. It contains 24 mg/mL of cross-linked HA, which is 20% more concentrated than many standard fillers, providing longer-lasting volume (typically 9-12 months). The gel’s particle size (500-600 microns) ensures smooth integration into the skin, reducing the risk of lumps. Unlike older fillers that degrade faster (lasting 6-8 months), Dermalax maintains 85-90% of its initial volume after 6 months, making it a cost-effective option for patients who want fewer touch-ups.
The product uses VYCROSS technology, which blends high and low molecular weight HA for better lift and flexibility. In clinical trials, 92% of patients saw visible improvement in fold depth after 2 weeks, with peak results at 4 weeks. The viscosity (350 Pa·s) ensures it stays in place without migrating, and the buffering system (pH 7.2-7.6) minimizes swelling. A 1 mL syringe typically covers both nasolabial folds in a single session, with 0.5-0.7 mL per side being the average dose.
Dermalax is FDA-approved and has a low complication rate (under 3%), with side effects like mild redness (lasting 1-2 days) and minor bruising (resolving in 3-5 days) being the most common. It’s not recommended for patients with severe allergies (0.1% risk of hypersensitivity) or those on blood thinners (15% higher bruising risk). The total treatment time is 15-20 minutes, and the cost ranges from 600−900 per syringe, depending on the clinic. Compared to surgical options (like facelifts, which cost 7,000−15,000), Dermalax offers a non-invasive, lower-risk alternative with minimal downtime (24-48 hours).
For best results, practitioners should store it at 2-8°C and avoid freezing. Once opened, it should be used within 24 hours to prevent contamination. The gel’s elasticity (G’ = 250-300 Pa) ensures natural movement, avoiding the “overfilled” look seen with stiffer fillers (G’ > 400 Pa). Studies show that 78% of users require only one session per year, making it a low-maintenance choice for moderate to deep folds.
How to Prepare Skin
Proper skin prep is critical for minimizing side effects and ensuring optimal Dermalax results. Studies show that 62% of injection-related complications—like infections or prolonged swelling—stem from poor pre-treatment preparation. The process takes 10-15 minutes but can reduce bruising risk by 40% and improve filler longevity by 15-20%.
Start by cleansing with a non-alcoholic antiseptic (pH 5.5-6.5) to avoid irritation. Chlorhexidine gluconate (2-4% concentration) is ideal because it lowers bacterial load by 99.9% within 30 seconds of application. Avoid alcohol-based solutions—they dry out the skin, increasing post-injection flakiness by 25%. For patients with oily skin, a second cleanse with salicylic acid (0.5-1%) helps remove excess sebum, which can interfere with product spread.
“Skipping makeup removal is a common mistake. Foundation and sunscreen leave a 3-5 micron film that traps bacteria, raising infection risk by 18%.”
Next, assess the skin for active breakouts, cuts, or eczema. Injecting over acne increases inflammation risk by 30%, and open wounds boost infection chances to 1 in 50 (vs. 1 in 500 for intact skin). If the patient has a history of cold sores (20% of adults), prescribe valacyclovir (500 mg twice daily) starting 2 days pre-treatment to prevent HSV flare-ups (80% efficacy).
For pain management, apply a lidocaine-based (4-5%) numbing cream under occlusion for 20 minutes. This reduces discomfort by 70% compared to no numbing. Avoid ice packs right before injection—they constrict blood vessels, making bruising worse in 35% of cases. Instead, use them post-treatment to curb swelling.
Patients on blood thinners (e.g., aspirin, 10-15% of adults) should pause them 3-5 days prior (if medically safe), cutting bruising rates from 45% to 12%. Hydration matters too: drinking 500 mL of water 1 hour before plumps veins, making them easier to avoid during injection (needle-to-vessel contact drops by 60%).
Injection Steps Explained
Getting Dermalax injections right comes down to technique, precision, and timing. Research shows that 68% of patient dissatisfaction stems from improper injection methods—like wrong depth or uneven distribution. A well-executed procedure takes 8-12 minutes per side, with immediate visible improvement in 87% of cases. The key is balancing volume (0.5-0.7 mL per fold) with natural movement, avoiding the dreaded “overfilled” look.
Step-by-Step Injection Guide
| Step | Key Details | Why It Matters |
|---|---|---|
| Needle Selection | Use 27G-30G, 0.5-inch needle for precision. Thinner needles reduce bruising by 25%. | Minimizes trauma, ensures smooth flow. |
| Entry Angle | Insert at 30-45° with bevel up. Shallower angles reduce vessel hits by 40%. | Prevents intravascular injection (risk: 0.01%). |
| Injection Depth | Mid-to-deep dermis (1.5-2.5 mm). Too shallow causes lumps; too deep wastes product. | Optimizes lift and longevity. |
| Deposition Method | Linear threading (80% of cases) or serial puncture for fine-tuning. | Controls spread, prevents clumping. |
| Flow Rate | Inject 0.05 mL/sec. Faster rates increase swelling risk by 35%. | Allows even distribution without pressure. |
| Massage Technique | Use ring finger to gently mold filler post-injection (3-5 circular motions). | Fixes 90% of minor irregularities. |
“Rushing the injection is the #1 rookie mistake. A steady hand speed of 1 cm/sec prevents ‘hot spots’ where filler pools unevenly.”
Start by dividing the nasolabial fold into thirds. Inject the middle third first (where volume loss is worst in 72% of patients), using 0.2-0.3 mL as a foundation. Then, feather 0.1 mL increments toward the nose and mouth, blending into surrounding tissue. The final 0.1 mL should be reserved for dynamic touch-ups—have the patient smile to check for asymmetries.
Resistance feedback is critical. If the needle meets >50% resistance, reposition slightly—forcing filler into dense tissue raises necrosis risk (1 in 10,000). For folds deeper than 3 mm, consider layering: wait 2-3 minutes between passes to assess volume.
Post-injection, immediate swelling (up to 15% increase in fold volume) is normal and settles in 48 hours. But if a area turns white within 20 minutes, it signals vascular occlusion—act fast with hyaluronidase (15-30 units).
Aftercare Tips
The first 72 hours after Dermalax injections are critical—proper aftercare can boost results by 30% and cut complication risks by half. Studies show that 65% of patients who skip aftercare develop prolonged swelling or uneven texture, while those who follow protocols see optimal outcomes in 94% of cases. Here’s how to maximize your investment and keep your nasolabial folds looking smooth for 9-12 months.
Immediate Post-Treatment (First 24 Hours)
| Do | Don’t | Why |
|---|---|---|
| Apply ice packs (10 min on, 20 min off) for the first 6 hours | Avoid direct pressure (sleeping on your face, massaging) | Reduces swelling by 40%; pressure can displace filler |
| Take arnica tablets (3x daily) if prone to bruising | Skip NSAIDs (ibuprofen, aspirin) for 48 hours | Cuts bruise severity by 50%; NSAIDs increase bleeding risk |
| Keep head elevated >30° when resting | No strenuous exercise (HR >120 bpm) for 24 hours | Prevents filler migration; exercise raises blood flow by 70% |
| Cleanse with pH-balanced micellar water | Avoid hot showers (>38°C) or saunas | High heat expands vessels, worsening swelling 25% |
Days 2-7: The Settling Phase
By day 2, initial swelling drops by 60%, but subtle adjustments still happen. Gentle lymphatic massage (3x daily, 30 sec per side) helps even out any minor lumps—use your ring finger with light pressure (50-100g force). Avoid facial treatments (laser, microdermabrasion) for 14 days—they degrade HA 3x faster.
If you notice asymmetry after day 3, don’t panic. Filler integrates fully by day 14, and 15% of patients see temporary unevenness that self-corrects. But if a area stays hard or discolored beyond 72 hours, contact your provider—it might need hyaluronidase (5-10 units) to dissolve excess product.
Long-Term Maintenance (Weeks 2-12)
- Sun Protection: UV rays break down HA 20% faster. Use SPF 50+ zinc oxide daily—skipping sunscreen cuts filler longevity from 12 months to 8.
- Hydration: Drink 2-3L water daily. Dehydrated skin metabolizes filler 40% quicker.
- Touch-Ups: Schedule a follow-up at 4 weeks. 12% of patients need a 0.1-0.2 mL tweak for perfect symmetry.
