It will indeed! I'm 44 and still get carded for alcohol and cigarettes all the time, at least partly because from about the age of 17/18 I avoided the sun as much as possible. I was at Sephora the other day and this woman was demonstrating an exfoliating cream for me. I wasn't wearing any make-up, really, and she looked at me and very carefully said, "This is really good for anti-aging, too, and it looks like you might have the beginnings of some premature lines around your eyes, which this will help..." I kind of laughed and said, "Well, I'll be 45 in a few months, so they're not really premature." She practically fell all over herself apologizing and told me she thought I was in my early thirties. Now, I know she's trying to sell me things, but given how often that happens to me, and given that, you know, I own a mirror and can see for myself how relatively smooth my skin still is... Yeah, keep staying out of the sun, you will definitely be glad you did! :-)
