Retinol Therapy

Delia Cosmetics' Retinol Therapy is a lightweight retinol serum aimed at improving skin texture and reducing fine lines. The silky, fast-absorbing formula suits normal to oily and combination skin, and can be appropriate for retinol newcomers when used gradually. Fragrance-free and non-greasy, it targets signs of aging while maintaining a neutral sensory profile for routine layering under moisturizers.
