I was sold from the first try: Vitamin C is usually so unstable that it is difficult to buy any product that lasts long enough and maintains efficacy so as to do any good at all. Not so with Dermalogica "extreme c." The dry powder assures that the vitamin C will not degrade over time. The emulsion effect when applied assures delivery through a serum that penetrates the skin. This is unique as far as I can tell. I've tried many vitamin c products -- and liked a few -- but none have held up or impressed me as this one does! A must!

I didn't have high expectations when I bought this product. I've been using it for about a month now, and my skin looks great. It's brighter and tighter than ever before! I will keep using this product for a long time!!!
Unique delivery method makes ALL the difference! 
Good Product
