Phloretin is a polyphenol antioxidant derived from apple tree bark and leaves, commonly used in topical formulations to neutralize free radicals and enhance the photoprotective and brightening effects of other antioxidants like vitamin C and ferulic acid. It may also support skin barrier function and improve the penetration of co-formulated ingredients.

Erythema (redness) | Uncommon | Transient, typically resolving after application. |
Allergic contact dermatitis | Rare | Possible in individuals sensitized to the compound; patch testing advised. |
Dryness or peeling | Rare | Usually formulation-dependent rather than from phloretin itself. |
