for Dehydration
Nothing here targets dehydration directly; humectant hydration is the recognised companion to treating it, and this essence does that without known triggers.
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
- R8 → Supporting role. An active with early or mechanistic evidence only or an active researched for the concern and found wanting or an active with no evidence row for the concern yet; the product’s category job is a recognised companion to treating the concern.
q1 = plausible | none | not-assessed · supportive = true
Why this rule exists: The category's job (barrier care, humectant hydration, gentle cleansing, photoprotection) is the documented supportive role for this concern. This is the honest verdict for a moisturizer on an acne page.
