Be careful about mixing C with other products. C serums work best at fairly low ph's (acid). Creams, lotions are at higher ph's which make the C less effective, less able to penetrate the skin. I'd use your C first and then apply the other products.
The only exception I have heard about is using a glycolic acid to prep the skin for C. Since the glycolic removes dead skin, etc., the "new" skin is more receptive to the C. |
