The Collagen Stimulation Mechanism — A Deeper Look at How Biostimulatory Treatments Actually Work

Collagen is the most abundant structural protein in the human body, accounting for approximately 75% of the dry weight of skin. From the third decade of life onwards, its production declines at approximately 1% per year. Understanding how biostimulatory treatments reverse that process, and the precise biological mechanisms by which they do so, is not merely academic. It informs better clinical decisions, more honest patient conversations, and a more rigorous approach to treatment planning.
