for Dryness
Squalane is a reference standard by mechanism for dryness; this cream carries it high in the ingredient list.
A trial-supported active, or a reference standard by mechanism, at a working level; or a first-line active below its studied range.
- Rule
- R5 → Good choice. A supported active (trial-backed, or a reference standard by mechanism); declared at a working strength, or a labelled active or at a plausible but undeclared level.
q1 = supported · q2 = adequate | plausible
Why this rule exists: Trial-supported or guideline-supported active, adequately or plausibly dosed.
Rule R5 decided 9,843 verdicts across the catalog; “Good choice” is the verdict on 10,340 of 45,446. The full register. - Carrying active

for Dehydration
Nothing here targets dehydration directly; humectant hydration is the recognised companion to treating it, and this cream 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.

as a moisturizer
Judged as a moisturizer, it comes up short on: seals moisture in, supplies barrier lipids.
- Rule
- J3 → Falls short. Otherwise — when no earlier rule in this group matched.
Category job score below 65 over the features that can be measured from the label (5.1.0: unmeasured features no longer enter at a prior; when under half the spec's weight is measurable there is no job verdict). The sentence names the criterion missed, never 'its basics'. - Measured from the label
- draws in water, softens and smooths, seals moisture in, supplies barrier lipids, right weight for the job
- Tolerability
- Gentle
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.
