Poly-L-lactic acid (PLLA)

An Overview of Poly-L-lactic Acid in Skincare

Poly-L-lactic acid (PLLA), classified as a polymer, has become an integral part of the aesthetic skincare world. Hailed for its capacity to stimulate collagen generation, PLLA is regularly employed by professionals to correct shallow to deep facial wrinkles and folds.

What is Poly-L-lactic Acid?

Poly-L-lactic acid, commonly marketed under the brand name Sculptra, differs significantly from traditional fillers. Instead of filling lines with a gel-like substance, PLLA prompts your body to generate more collagen, resulting in a gradual increase in skin thickness. By encouraging natural collagen production over time, it offers subtle results that can last up to two years.

How Does Poly-L-lactic Acid Work?

When PLLA is injected into the skin, it works mainly by triggering an inflammatory reaction. This response stimulates fibroblasts - cells responsible for making collagen. The collagen produced aids in replenishing volume and improving skin elasticity lost due to aging or environmental factors.

Applications of Poly-L-lactic Acid

In aesthetic skincare, PLLA treatments are primarily used to treat facial lipoatrophy – loss of fat beneath the skin that can result in sunken cheeks or indented temples. Moreover, PLLA is widely used in non-surgical facelift procedures and to treat deep lines, creases, and folds.

Safety and Side Effects of Poly-L-lactic Acid

Being a biocompatible, biodegradable substance, PLLA carries minimal risk of allergic reaction. However, like any medical procedure, it comes with potential side effects, including injection site reactions such as redness, swelling or tenderness.

In conclusion, Poly-L-lactic Acid serves a crucial role in aesthetic skincare by promoting collagen production for more youthful-looking skin. But as with all skincare treatments, it's vital to consult with a professional before deciding if PLLA is the right choice for your skincare needs.
