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.

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".
barrier lipidCeramide NP, Linoleic Acid
- Ceramide NP: One of the lipid families the skin barrier is actually built from. Feingold KR and Elias PM, "The role of ceramides in the disruption of the cutaneous permeability barrier, a common manifestation of skin disorders", J Lipid Res 2024;65(8):100593, DOI 10.1016/j.jlr.2024.100593, open access: the barrier lipid matrix "by weight is approximately 50% ceramides, 25% cholesterol, and 15% free fatty acids".
- Linoleic Acid: An essential fatty acid the skin barrier uses and cannot make for itself. Khnykin D, Miner JH, Jahnsen F, "Role of fatty acid transporters in epidermis", Dermatoendocrinol 2011;3(2):53-61, DOI 10.4161/derm.3.2.14816, open access: "The human body can produce all but two of the fatty acids it needs: linoleic acid (C18:2, n6) and alpha-linolenic acid (C18:3, n3)", and replacing linoleic acid with a non-essential fatty acid "will lead to barrier defects". Feingold and Elias, J Lipid Res 2024: linoleate "is required for the synthesis of a subgroup of acylceramides".
