So I turned 25 earlier this week (yay!) and I've been noticing lately that I now have wrinkles (blah). They're only smile lines, and while my boyfriend finds them cute, it disturbs me that I'm showing signs of aging in my 20's already. I am a non-smoker, use 15 spf daily and try to stay out of the sun. I do have very fair skin and freckles, however. My skin care routine consists of cleansing twice a day, toner, using Aveeno Soy moisturizer with Salicylic acid in the morning and night, nightly eye cream, a mud mask and scrub 1-2 times/per week. My question is this: Should I be using glycolic acid and retinol cream already in my 20's as a preventative measure? Or is it completely unnecessary? Do the drug store brands like Olay Regenerist really work, or should I be investing in something more expensive? Any of your thoughts would be greatly appreciated.
