PLLA Filler ***PLLA filler is a type of dermal filler made from Poly-L-lactic acid, a biocompatible and biodegradable substance that has been used in various medical applications for decades. PLLA filler is injected into the skin to stimulate the production of collagen, a protein that provides structural support to the skin. ***The principle of action of PLLA filler involves a gradual process of collagen stimulation and production, resulting in an increase in skin thickness and firmness. When PLLA filler is injected into the skin, it creates a mild inflammatory response, which triggers the body's natural healing process. The body reacts to the PLLA microspheres by producing new collagen, which helps to replace lost volume and smooth out wrinkles and fine lines. ***Over time, the PLLA microspheres are gradually absorbed by the body, leaving behind the new collagen that has been produced. This process takes several months and typically requires multiple treatments spaced several weeks apart. The results of PLLA filler can last up to two years, making it a popular choice for those seeking long-lasting facial rejuvenation.
