    Coverage & match quality

    5 ratings · 3 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 we know about the packaging

    Partly identified·1 of 2 identified

    1 of 2 packaging components is a named material; Plastic (unspecified) is recorded only in general terms, so that part of the score is a stand-in.

    • Recorded only as “plastic” — no resin code. It could be PET (#1) (widely recyclable) or PVC (#3) (hard to recycle); nothing on record says which, so it counts as 46 out of 100, the middle of that range.

    This says how precisely the packaging is described, not how good it is — a fully identified material can still be a bad one.

    How we know the packaging

    Read from the product photo, not declared by the maker — treat this score as weaker.

    The container looks like this, rather than the maker saying so. A photo also cannot show the resin code moulded into the base, so every plastic container reads as “plastic, unspecified” — the cautious end of the plastics range, not a finding about this particular pack.

    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".
    • soothingNIACINAMIDE

      • NIACINAMIDE: A vitamin B3 form that supports the skin barrier and has anti-inflammatory activity; it turns up in products aimed at acne, rosacea and eczema. Camillo L, Zavattaro E, Savoia P, "Nicotinamide: A Multifaceted Molecule in Skin Health and Beyond", Medicina (Kaunas) 2025;61(2):254, DOI 10.3390/medicina61020254, PMID 40005371, open access: it "is extensively used in ... the treatment of dermatological conditions such as blistering diseases, atopic dermatitis, rosacea, and acne vulgaris", and contributes to reducing inflammation. On the acne evidence specifically: Liu H, Yu H, Xia J, Liu L, Liu GJ, Sang H, Peinemann F, "Topical azelaic acid, salicylic acid, nicotinamide, sulphur, zinc and fruit acid (alpha-hydroxy acid) for acne", Cochrane Database Syst Rev 2020;5:CD011368, DOI 10.1002/14651858.CD011368.pub2, PMID 32356369, records "low-quality evidence" for every nicotinamide comparison it could pool, and none of its four nicotinamide studies measured the physician global assessment at all.
