Commercially known as : Sculptra
Polylactic acid is a synthetic dermal filler that is injected into your face, causing your body’s own production of collagen. This type of dermal filler is known as a stimulator. This non-toxic, biodegradable substance has been used for more than 40 years as suture material.
Polylactic acid is known to work particularly well in the lower half of your face, and is used to:
- Fill the lines caused by laughing
- Plump thin lips
- Treat deep nasolabial folds
This substance is unlike other dermal fillers because it doesn’t produce immediate results. Instead, it stimulates your own body’s collagen production, so results appear gradually over a period of a few months.
You will likely need about three monthly treatments to achieve your desired results. With each treatment, there is re-stimulation of your own collagen. Then it can take four to six weeks to see the full effect. While this type of dermal filler is considered semi-permanent, you may still need occasional touch-ups.
