The importance of exfoliation cannot be overstated, even if you've got sensitive skin. You'll have to experiment to figure out how often you need to do it—every day, twice a week, etc.—and what strength works best for you, but it's always better to start with a milder or less abrasive product. Never scrub so hard that you cause irritation—think of sweeping dead skin cells away lightly and you're on the right track.
