Tesoro is formulated without lidocaine, which removes concerns associated with cumulative anesthetic doses and suits practitioners who prefer to manage anesthesia separately, for example with a topical or local protocol of their choosing. Patients or practices that want a built-in anesthetic would choose a lidocaine-containing filler instead.

According to available sources, Tesoro is described as minimally invasive and able to be administered without prior anesthesia, owing to its high density and viscosity that allow controlled, localized placement. The treating practitioner makes the final decision on comfort measures for each patient.

Sources consistently report results lasting around 12-15 months, extending up to about 2 years with proper maintenance. As a biocompatible gel, it gradually dissolves through normal metabolism, so periodic repeat treatment maintains the outcome. Individual duration varies with area, volume, and metabolism.

It is positioned for non-surgical contouring of the breasts, buttocks, thighs, and calves, and for smoothing skin-surface irregularities that can follow liposuction. It should not be injected into tendons, muscles, bone, or blood vessels, nor used around the eyes or brow ridge.

Tesoro comes as a disposable, terminally sterilized 60 ml vial that is ready to use, with no saline reconstitution required. The high-volume single vial suits large body areas. It is for single-patient professional use only.
