Obagi Medical has introduced its Retinol + PHA Refining Night Cream, a dermatological skincare innovation designed to enhance skin renewal while minimizing irritation. The formula combines encapsulated retinol — a slow-release vitamin A derivative that gradually penetrates skin layers — with polyhydroxy acid (PHA), a mild exfoliant that refines texture without the sensitivity risks associated with stronger acids.

Clinically tested over four weeks, the Retinol + PHA Refining Night Cream demonstrated measurable improvements in smoothness, tone, and blemish reduction, with 90% of participants reporting visibly refined skin. Additional supportive ingredients like sodium hyaluronate, squalane, and vitamin E bolster hydration and barrier protection, making the product suitable for those new to retinoids or with reactive skin. Obagi Medical positions its product as a gentler alternative to traditional retinol treatments.
