Quick answer
Collagen biostimulators are injectable substances that stimulate the skin to produce its own collagen. Rather than filling, they help improve firmness and skin quality gradually, over weeks to months. Usually one to three sessions are needed, set at the assessment.
How they work
Once injected, the biostimulator triggers a tissue response that leads to new collagen production. The result is not immediate: the skin gains firmness progressively. This differs from hyaluronic acid, which restores volume immediately.
Who it may suit
It may suit mild to moderate laxity of the face, neck or some body areas, and people looking for gradual, subtle improvement. It is not suitable during pregnancy and breastfeeding, with active infection in the area or with some autoimmune conditions, among other situations.

How it works in practice
The doctor applies the product with a needle or cannula in the agreed areas. There may be swelling, tenderness or bruising in the following days. Sometimes massaging the area for a few days is advised, depending on the product.
When results show
Improvement usually starts to show over the following weeks and develops over a few months. Duration varies with each body, age, habits and sun protection.
