New cosmetic injection of poly-L-lactic acid (PLLA), a synthetic substance that triggers cells called fibroblasts in the skin to secrete collagen.
Have you ever heard of poly-L-lactic acid (PLLA) and do you use it in your practice?
Poly-L-lactic acid (marketed in the US as Sculptra) is a soft tissue filler used mostly in AIDS patients to temporarily improve atrophy of the soft tissues of the face. I am not sure how much collagen synthesis it really encourages and don’t use it as it is quite expensive. There are too many soft tissue fillers on the market. None of the safer fillers last very long and the permanent ones tend to be associated with many problems.
