A recommendation for a good Vitamin C serum?
The SkinCeuticals (try the Phloretin CF or the AOX 20, the C&E Ferrulic is probably the best but a little more irritating) and Cellex-C serums are excellent. They can be a little sticky under makeup which bothers some people. Try the SkinMedica Vitamin C if you think that might bother you. Put your sunscreen or moisturizer over it.
Use the 20% if you’re skin is NOT easily irritated and try the 10% if it is. The 10% can still be too strong for some in which case try going with the Replenix green tea 90% polyphenol cream. Hope this helps! Dr. I
