Everything behind the verdicts on this product: the rule that fired for each concern, the three answers and the documents they rest on, every study on the row with the date it was opened, and the versions of the tables that produced them. Nothing here is edited by hand; it is generated from the same records the verdicts are.

for Aging
Niacinamide has early evidence for aging, and hydration and barrier support is the recognised companion to treating it — a reasonable supporting choice, short of a recommendation.
Nothing here targets the concern directly, but the product’s job — barrier care, gentle cleansing, photoprotection — is the recognised companion to treating it. Rinse-off products carrying leave-on actives land here too.
- Rule
- R8a → Supporting role. An active with early or mechanistic evidence only; declared at a working strength, or a labelled active or at a plausible but undeclared level; the product’s category job is a recognised companion to treating the concern.
q1 = plausible · q2 = adequate | plausible · supportive = true
Why this rule exists: A plausible-tier active in a category with a supportive job: the sentence names the active instead of saying nothing targets the concern (the AmLactin / CeraVe SA case for keratosis pilaris, where no guideline and single trials leave the keratolytics at early evidence).
Rule R8a decided 1,509 verdicts across the catalog; “Supporting role” is the verdict on 7,796 of 45,446. The full register. - Carrying active

Listed for Rough Texture, with no verdict: the actives here have no evidence row for that concern yet. That is a gap in our table, not a mark against the product.
- Rough Texture: The actives here (Panthenol (Vitamin B5), Matrixyl Peptides, Niacinamide, Shea Butter) are in the research queue for rough texture; no verdict until their rows are written.
A verdict is Dermington’s assessment of how well a product’s ingredients fit a concern — never a claim about what the product treats. Every rule is public and the same for every product; a brand cannot buy a reading. How we decide · what has changed · disclaimer.
