"Don't have time even to pick up an at-home peel? Try this secret weapon, a favorite of mine and many of my colleagues: Spread a thick layer of your regular retinoid (Retin-A, Differin, and Tazarac are among the most popular of these vitamin A-based topical creams) on your face. In 3-5 days your skin will start peeling, but by day 6 you'll be positively radiant (so plan your schedule accordingly!)."
