Poly-L-lactic acid (PLLA) is a biostimulator that has been widely used in aesthetics for skin regeneration.
- Poly-L-lactic acid (PLLA) is a biodegradable synthetic polymer that has been used in various medical applications, including aesthetic medicine.
- When injected into the skin, PLLA stimulates an immune response that attracts fibroblasts to the skin. This triggers the production of new collagen fibres. PLLA also acts as a bioabsorbable scaffold, facilitating the process of neocollagenesis.
- PLLA is unique in that it works gradually, with results appearing over several months. There is no initial filling effect, and a slow and steady rejuvenation process allows for a natural-looking improvement in the skin’s texture, elasticity, and thickness.
- Results with PLLA are optimised by doing a course of treatments – just as repeated fertiliser treatments of your soil will create the optimal environment for your garden to grow.
- PLLA is gradually broken down and metabolized by the body over time, but its effects on collagen production can last for up to two years or more.
- Outside of aesthetic medicine, PLLA is also used in medical devices, such as sutures and implants, due to its biocompatibility and biodegradability. It has been extensively studied and approved by regulatory agencies for various medical and cosmetic applications.
- Injectable biostimulators should only be injected by experienced and trained medical doctors.
