| this is the only ascorbic acid I can tolerate--after rejecting skinceuticals, obagi and is clinical. Choke full of A antioxidants, and other chemicals like tyronise and zinc that actually deliver ascorbic acid deep enough in the cells where it is needed for collagen. It does not sting, and is very slippery and moisturzing due to hylauronic acid. I use it twice a day, even though the directions say only once every 24 hrs. Results in about 2 months. It does turn brown very soon though. |
