INCI: Hydroxypinacolone Retinoate · Also called: HPR, Granactive Retinoid

The retinol-without-the-irritation active marketed as Granactive Retinoid. It works on fine lines and acne-prone texture with far less flaking than prescription-style retinoids, which makes it beginner-friendly. Use at night, with daytime SPF.

Mechanism of action

An ester of retinoic acid that binds skin retinoid receptors directly, without the multi-step conversion that retinol requires; this delivers retinoid effects on turnover and collagen with a lower irritation profile.

Why we tier this moderate

2 cited papers across 2 countries. The mechanism is well-described and there's at least one controlled trial in the literature, but we tier this Moderate rather than Strong to stay honest about how many specific papers we cite directly.
