What we review
Scope constraints are a quality signal. CosmeticFountain starts narrow so its methodology, grade language, and update process become reliable before expanding.
Year-one priority clusters: retinoids, vitamin C, AHAs, niacinamide, peptides, and closely related claim families.
Priority goes to claims with high consumer interest, marketing overreach, safety context, regulatory ambiguity, or meaningful disagreement in the evidence.
Devices, body care, haircare, fragrance, and makeup performance claims can be queued, but broad expansion should wait until the first skin-active cluster is consistent.
The site should eventually show requested reviews and next-up dossiers so readers understand that absence from the index is scope, not avoidance.
