Science
Mechanism of Action
Operating at multiple cutaneous levels, Hydrolyzed Collagen Extract primarily functions as a humectant, attracting and retaining moisture within the stratum corneum to significantly reduce dryness and restore suppleness. Its composition includes free amino acids that act as vital precursors for endogenous collagen and elastin synthesis within the dermis. Furthermore, specific collagen oligopeptides stimulate fibroblasts to produce new collagen, elastin, and hyaluronic acid, thereby diminishing the appearance of skin aging signs such as laxity and wrinkles. It also serves as an emollient and film-former, contributing to improved skin texture and barrier function.

Key findings
- 01 Studies indicate that concentrations ranging from 0.2% to 2.0% are typically effective in reducing the appearance of dry or damaged skin, restoring suppleness, and minimizing flaking.
- 02 Topical application of 8.0% hydrolyzed collagen, with a molecular weight between 5 and 13 kDa, has been shown to penetrate the skin, promote fibroblast cell proliferation, and stimulate collagen I secretion, suggesting deeper dermal benefits.
Transparency
Dusting Analysis
Hydrolyzed Collagen Extract is a highly water-soluble ingredient, typically incorporated into formulations in liquid form, rendering the concept of 'dusting' as a concern for underdosing or poor efficacy largely inapplicable.
The Formula
Formulation
Stability
Highly soluble in both cold and hot water. While it contributes to film formation, it requires co-formulation with other biopolymers to achieve a complete and stable film.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has consistently deemed Hydrolyzed Collagen safe for cosmetic use, reaffirming this conclusion in reviews conducted in 2006 and 2017. Clinical assessments have demonstrated no evidence of skin irritation, sensitization, or phototoxicity. Its use is permitted in Europe under general cosmetic regulations, and its source material, gelatin, is classified as safe by the FDA.
