I just read an article on prevention
(www.prevention.com/article/0,5778,s1-5-84-89-6918-1,00.html) that said that due to stability issues antioxidants like C & E should be applied at night. I only do retinoids or retinol at night and do a C serum under my sunscreen at day (I used skinceuticals serum 15 for years, then tried LRP active C and am currently waiting for a CE Ferulic that I bought on ebay). Have I just been spending my entire time under a rock or is that something some of you guys do as well? I am an ORNT with no major issues except prevention.
