How does DemythSkin score skincare products?
DemythSkin scores every product out of 5.0 on two separate axes: Efficacy (does the formula deliver its claims?) and Safety (will it irritate?). Ingredients are graded S Tier (gold standards, high clinical proof), A Tier (reliable), B Tier (supporting), C Tier (overhyped | marketing) and D Tier (documented irritants โ added fragrance, drying alcohol, essential oils). Preservatives, emulsifiers and thickeners are shown as formulation base and count as neither good nor bad, because treating them as hazards is fear rather than science.
