Science & review
How we make Molecool
Skincare advice is full of hype and fear. Here’s how we decide what to say, how sure we are, and what we won’t do.
Where our facts come from
- Peer-reviewed studies and review articles, linked on every page.
- Regulators and medical centers, such as the US FDA and university health systems.
- We say how big and how long a study was when it matters, especially when it was small.
- When the evidence is mixed, we say so. For example, ceramide moisturizers helped eczema severity but weren’t clearly better at reducing water loss.
How we rate evidence
StrongRegulatory approval or several good trials agree
ModerateGood studies, but fewer or shorter ones
LimitedSmall, short or lab-only studies
Expert review
Every page is written from sources, then checked by a dermatologist or cosmetic chemist before it’s marked as reviewed.
Right now, all pages are drafts. Each one shows a “pending review” label until a reviewer signs off, with their name and the date.
What we won’t do
- Diagnose skin conditions or analyze photos of your skin.
- Use fear-based “toxic” labels for ingredients that are safe at normal amounts.
- Let affiliate links change what we recommend.
- Claim results the evidence doesn’t support.
Affiliate links
When product picks launch, some links will earn us a commission at no extra cost to you. They’ll be clearly marked, and the educational advice on each page stays the same whether or not a product has a link.
