In the research
5 PubMed papers mention it with skin, cosmetics or hair; the three most recent:
- Permeation behaviour of cosmetic actives into the human stratum corneum · International journal of pharmaceutics, 2026
- Mechanistic understanding and peptide ingredient screening for type III collagen via biological knowledge graph and molecular docking · International journal of cosmetic science, 2026
- Comprehensive evaluation of the efficacy and safety of a new multi-component anti-aging topical eye cream · Skin research and technology : official journal of International Society for Bio, 2024
A paper is a paper, not a verdict: titles are listed so you can read them, and a study on cells or mice says little about a cream on a face.
