Collagen is often a buzzword used in the beauty industry to promote certain products and treatments, but it’s more than a marketing tactic. Collagen makes up a third of the proteins found in the human body, responsible for the strength and support of the skin, bones, muscles, tendons, and ligaments. In the context of skincare, it’s vital for keeping skin looking plump and youthful.
As we age, collagen levels deplete at a rate of 1% per year, which is why collagen stimulators, such as PLLA, are a great solution for rejuvenating the complexion. Rather than simply filling lines or adding volume, PLLA (Poly-L-lactic acid) stimulators work by encouraging the body to rebuild its own collagen, resulting in restored firmness, volume, and skin integrity from within.
In this guide, we’ll break down everything you need to know about PLLA stimulators and how they work.
What is Poly-L-Lactic Acid?
Poly-L-lactic acid (PLLA) is a biocompatible, biodegradable synthetic polymer that has been used safely in medicine for decades, including in dissolvable stitches and orthopaedic implants. In aesthetics, it's the hero ingredient in collagen-stimulating injectables designed to gradually rebuild the skin’s structural foundation.
What Do PLLA Stimulators Do?
Unlike hyaluronic acid (HA) dermal fillers that offer immediate volume, PLLA stimulators work gradually, helping to improve facial contours and skin thickness by triggering natural collagen production.
They’re designed to treat volume loss, improve skin laxity, and restore facial support over a period of months. When injected into the deep dermis, the microparticles of Poly-L-lactic acid stimulate fibroblasts, the cells responsible for producing collagen.
Benefits of PLLA Stimulators:
-
Restoring lost volume in the face
-
Smoothing out lines and wrinkles
-
Improving skin texture and laxity
-
Enhancing skin structure and quality
-
Long-term results
How Do Collagen Stimulators Work?
When injected into the skin, PLLA particles prompt a mild inflammatory response, which triggers the body’s natural healing process, encourages fibroblast cells to produce more collagen and elastin around the injected areas.
Over time, the body goes through its cell-renewal process and absorbs the PLLA, leaving behind the newly-formed collagen. This isn’t an immediate process. Results will differ depending on the client, but they usually take between several weeks and months to appear.
How Long Do PLLA Stimulators Last?
One of the key advantages of PLLA stimulators is their longevity. The results of a collagen stimulator can last up to 2 years or more with proper maintenance, as the newly produced collagen provides the skin with long-term support.
