I just did a google for it..

but i could only find basic directions for use. i'd suggest putting it on before your moisturiser because it's a treatment.. cus my doctor told me to use the stuff for my psoriasis on
before my usual moisturiser. so i dunno. i shouldnt think it would matter too much to be fair.. or maybe let the moisturiser sink in and then use the mederma?
eep.
