What Is Injectable Poly-L Lactic Acid Used For?

If you are at least 18 years old and want to correct facial fat loss or wrinkles, you may benefit from injectable poly-L lactic acid. Using this product can help stimulate the body to make new collagen. There are also some unapproved ("off-label") uses for this product, including treating other areas of the body besides the face.

An Introduction to the Uses of Injectable Poly-L Lactic Acid

Injectable poly-L lactic acid (Sculptra®) is a facial filler. It is used for the following two purposes:
 
  • To correct facial fat loss (lipoatrophy) in people with HIV
  • To correct wrinkles, lines, and facial folds (for cosmetic purposes).
     
There are actually two different injectable poly-L lactic acid products. Regular Sculptra, which is approved for the HIV-related facial fat loss, and Sculptra Aesthetic, which is approved for the cosmetic purposes. There are no important differences between the two products, other than the conditions they are approved to treat.
 

Injectable Poly-L Lactic Acid for Lipoatrophy

Lipoatrophy (fat loss) is a common side effect of many of the medications used to treat HIV. This side effect can be very distressing. It is distinctive enough to arouse suspicion about a person's HIV status and often gives a person a general appearance of being "unwell" or sick. For some people, facial lipoatrophy is so distressing that they may consider stopping their HIV medications.
 
Although switching HIV medications often corrects facial lipoatrophy, it does take time. Additionally, in some cases the lipoatrophy may be permanent. Therefore, treatment is sometimes desirable. Injectable poly-L lactic acid helps to plump the sunken areas and reduce the folds that have developed. This product is typically used to fill in areas of the cheek and temples.
