In the research
495 PubMed papers mention it with skin, cosmetics or hair; the three most recent:
- HIFU-Enhanced Transdermal Delivery of Hyaluronic-Acid-Functionalized Solid Lipid Nanoparticles for Localized Melanoma Therapy · ACS applied materials & interfaces, 2026
- Optimization and Mathematical Modeling of Biocompound Extraction from Pterocaulon Species Using Deep Eutectic Solvents · Molecules (Basel, Switzerland), 2026
- Metabolic engineering of Saccharomyces cerevisiae for de novo biosynthesis of aesculin and cichoriin · Journal of biological engineering, 2026
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.
