Obagi Exfoderm is an exfoliating lotion that contains phytic acid, which is gentler than AHAs, in a soothing base to smooth and tone rough or damaged skin. It helps with keratolytic and exfoliating activity. It also helps enhance the activity of hydroquinone and tretinoin. Obagi Exfoderm is indicated for dry, thin, or sensitive skin and is to be applied in the morning after the application of Obagi Clear.
