Reborn PLLA dermal filler is a type of injectable filler that is made from poly-L-lactic acid (PLLA) which is approved by FDA that a biocompatible and biodegradable substance that stimulates collagen production in the skin. When PLLA dermal filler is injected into the skin, it triggers the body's natural collagen production process. Over time, the newly produced collagen fills in wrinkles and lines, resulting in a more youthful and plump appearance. There is typically little to no downtime after PLLA dermal filler injections, and most people can return to their normal activities immediately. However, some swelling, redness, and bruising may occur, which can take a few days to resolve.
