About OBAGI - Retinol 0.5
In short: A 0.5% retinol cream from Obagi that releases retinol gradually to smooth fine lines, wrinkles and rough texture with minimal irritation. It is the middle strength between Retinol + PHA (0.3%) and Retinol 1.0.
Obagi Retinol 0.5 28g
Obagi Retinol 0.5 is a cream-based 0.5% retinol for evening use. It renews the skin and gradually releases its actives to reduce the look of fine lines and wrinkles and promote skin turnover, with minimal irritation. Calendula, green tea, chamomile, bisabolol and hyaluronic acid help keep skin comfortable.
It is a good next step once your skin is used to Retinol + PHA, before moving to Retinol 1.0. Retinol is a cosmetic retinoid, not prescription tretinoin. Genuine Obagi Medical stock from Obagi’s UK distribution.
