I'm not a doctor, nor do I play one on TV, but I do know that we need to shed those icky old dead skin cells to have our skin glowing and youthful!
Keep an exfoliating facial cleanser in the shower so you'll remember to use it everyday. My favorite right now is Olay Regenerist Advanced Anti-Aging Cream Cleanser. Claim on the tube says "exfoliates to detoxify and speed cells' natural regeneration process"; I believe it!
Don't forget a body scrub too! I have bought some great handmade ones on http://www.etsy.com/ (I'll try to get the specific shop names if you want). Right now I'm using Softsoap Spa Radiant Body Wash. "Exfoliating with mineral sea salts". It smells great and I love the color (told you I wasn't a doctor).
So slough away and be radiant!
