What it is
Atelocollagen is collagen that has had its highly antigenic telopeptide ends enzymatically removed to reduce immunogenicity, and the succinoyl version is further modified by succinylation to improve its solubility and handling in water-based formulas. In cosmetics it acts as a conditioning, moisture-binding agent that can form a smooth film on the skin surface, contributing to a soft, hydrated feel. It is used as a supportive ingredient and does not contribute to UV filtration.
Safety & warnings
Atelocollagen is designed to have reduced immunogenicity compared with native collagen because the antigenic telopeptides are removed, and topical use is generally well tolerated. It is not a recognized fragrance allergen.
Origin & sourcing
Derived from animal collagen, typically processed to remove telopeptides to form atelocollagen, then chemically modified with succinic anhydride to yield the succinoyl form.
Questions everyone asks
What is atelocollagen?
It is collagen whose antigenic telopeptide ends have been removed to lower its immunogenicity, making it better suited for cosmetic and biomedical use.
Why is the collagen succinylated?
Succinylation modifies the protein to improve its water solubility and stability so it disperses and performs well in water-based skincare formulas.
