These two serums take different paths to a similar destination. Both formulas include solid hydrating ingredients, and the overall scores reflect that — the gap here is genuinely slim.
Paula's Choice Clinical 1% Retinol Treatment brings Retinol, Tetrahexyldecyl Ascorbate, and Palmitoyl Oligopeptide as actives, while paula's Choice Mini Must-Haves with 2% BHA Exfoliating Toner, Foaming Cleanser, & SPF 50 relies on Ceramide Np, Ceramide Ap, and Ceramide Eop. Both approaches have merit, but the positioning and supporting ingredients make the difference.
Both sit in the mid-range bracket, so value comes down to formulation quality. Paula's Choice Clinical 1% Retinol Treatment gets the nod here with its 8.9 overall score — you're getting more for a similar outlay.
