Ducray Ictyane Cleansing Cream
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 Dryness
Rinse-off cream: Glycerin gets seconds of contact, so this supports a routine for dryness rather than treating it.
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
- R6 → Supporting role. A first-line active (approved, monograph-listed or named in a current guideline) or a supported active (trial-backed, or a reference standard by mechanism) or 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; in a rinse-off form the claim cannot use.
q1 = first-line | supported | plausible | none | not-assessed · q2 = contact-limited
Why this rule exists: Contact time cannot deliver a leave-on claim; the product is judged on its job (cleansing without aggravating). Explicit exceptions (BPO wash, SA cleanser, medicated shampoos) never reach this rule because their rows set rinse_off_ok.
Rule R6 decided 2,083 verdicts across the catalog; “Supporting role” is the verdict on 7,796 of 45,446. The full register. - Carrying active

for Dehydration
Rinse-off cream: Glycerin gets seconds of contact, so this supports a routine for dehydration rather than treating it.
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.

Listed for Winter Skin, 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.
- Winter Skin: The actives here (Cleansing Surfactants, Glycerin, Safflower Oil, Sweet Almond Oil) are in the research queue for winter skin; no verdict until their rows are written.
- Fragrance
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.
