Obagi Nu-Derm 4 Exfoderm 57g

AHA skin smoothing lotion for normal to dry skin, the gentler sibling of Exfoderm Forte. It uses a milder acid blend to loosen dull surface cells so the brightening steps that follow can actually reach the skin underneath.

Apply after cleansing and toning, in the morning, then follow with sunscreen. Exfoliating acids make skin more sun sensitive, so daily SPF is part of using this properly rather than an optional extra. Which Exfoderm suits you is a question of skin type rather than ambition: dry and normal skin belongs on this one, and oily skin generally does better on the Forte. Using the stronger version because it sounds better is how people end up with a compromised barrier.
