i've started using vitamin c regularly and like how it's helping my dark marks fade and my skin seem brighter. i still like the acne fighting powers of bha and the dark mark fading power of glycolic acid.

my question is, if i want to use my vitamin c can i layer either of the other products too and if so in what order? OR is it best to wear them one at a time in rotation? (i.e. mon vit c, tues bha, wed glycolic acid, etc)
