"This two-step Dr. Dennis Gross Clinical Grade Resurfacing Liquid Peel ($95) is some potent stuff. It uses a pro-level mix of acids to exfoliate the skin and refine pores, reduce the appearance of fine lines, and boost radiance. Step one accelerates skin renewal for a smoother complexion, while step two is a corrective treatment that neutralises peeling activity. Despite its powerful punch, the formula is non-drying and gentle on my skin." — Jessica Harrington, assistant editor, Makeup.com and Skincare.com
