Retinol Quiz: Find Your Retinol

Find your retinol

Retinol is the best-evidenced ingredient in cosmetic skincare — and the most commonly misused. Nearly every bad experience people report comes down to the same two mistakes: starting too strong, or moving up too fast.

Strength should follow experience, not ambition. Starting at 0.25% isn't cautious — it's optimal, because tolerance your skin builds slowly is tolerance it keeps. Our quiz places you on that ladder honestly: where you are with retinoids today, what you want the retinol to work on, how resilient your skin is, and whether you'd rather it came as a night cream or a dedicated treatment. The eye area gets its own consideration — that skin is thinner and deserves a formula dosed for it.

Whatever the result: evenings only, a pea-sized amount, two nights a week to begin, and sunscreen every morning without exception.
