Coverage & match quality
5 ratings · 1 of 4 axes
- Some ratings rest on an automatic match that has not been human-reviewed.
- Fewer raters reach smaller-brand products, so a missing rating is not a clean bill of health, only a gap.

What these ingredient tags mean (2)
These describe what an ingredient is, not whether it is a problem. The stance marks above are the ratings; these are not.
retinoidretinol
- retinol: A vitamin A derivative that speeds skin turnover; dryness and flaking while skin adjusts are its usual accompaniment. SCCS Opinion on Vitamin A (Retinol, Retinyl Acetate, Retinyl Palmitate), SCCS/1576/16, final version of 6 October 2016; Commission Regulation (EU) 2024/996 added the group to EU Regulation (EC) 1223/2009 Annex III entry 376, capping it at 0,05% retinol equivalent in body lotion and 0,3% in other leave-on and rinse-off products, with the label statement "Contains Vitamin A. Consider your daily intake before use."
humectantglycerin
- glycerin: A humectant, and one of the two ingredients a comparison of moisturiser components found made a significant difference to skin hydration. FDA OTC skin protectant monograph, 21 CFR 347.10(h), lists glycerin as a skin protectant at 20 to 45%. On the humectant half: Jeong CB, Han JY, Cho JC, Suh KD, Nam GW, "Analysis of electrical property changes of skin by oil-in-water emulsion components", Int J Cosmet Sci 2013;35(4):402-410, DOI 10.1111/ics.12059, PMID 23621673, found that "glycerine and urea showed significant skin hydration effects compared with other humectants".
