Over the years, the skin's natural collagen production progressively decreases, resulting in sagging and loss of firmness in the face, neck and décolletage. Collagen biostimulators work differently from fillers: instead of directly restoring volume, they stimulate the skin itself to produce more collagen.
What are collagen biostimulators?
Biostimulators are biocompatible substances — such as poly-L-lactic acid and calcium hydroxyapatite — applied to the skin to activate fibroblasts, the cells responsible for collagen production. The result isn't immediate like a filler: it builds up gradually, as the body itself produces new collagen.
Biostimulator or filler: what's the difference?
Confusion between the two procedures is common, since both are injectables. Filler, usually hyaluronic acid-based, immediately restores volume in a specific area. A biostimulator, on the other hand, doesn't fill — it stimulates the skin to produce collagen progressively, improving firmness and skin quality more broadly. The two can even be combined in the same treatment plan.
Who is it indicated for
Collagen biostimulators are mainly indicated for:
- Mild to moderate sagging in the face, neck and décolletage.
- Loss of firmness and elasticity associated with aging.
- Prevention of aging in younger skin, before sagging sets in.
- A complement to other protocols, such as peeling and botulinum toxin, to enhance skin quality.
How many sessions are needed?
The number of sessions varies according to the product used and each patient's individual response, but usually involves more than one application, spaced weeks or months apart, to build the result gradually. The initial assessment defines the protocol and interval best suited to each case.
Care after application
After application, the professional may recommend specific massages in the treated area, as well as avoiding intense sun exposure and vigorous physical exercise in the first few days, so the product distributes evenly in the skin.
