Hi! I'm really interested in investing in my skincare, I'm 21 and not sure what to do. Ive heard that prescriptive's is meant to be amazing, I have used some dermalogica in the past, but not avidly, I know they are also meant to be of a good standard. My dilemma is I want to protect against aging as much as possible, I already use a high spf in my moisturiser and eye cream, is this sufficient even if it is just a cheap brand, or are there much more important factors to be considering to keeping my skin youthful! If anybody has any advice as to what skincare route I should go down pleasehelp!!!!
