Someone recently commented on laughter lines around my eyes, and I've been paranoid since then. Popped down to the local chemist/pharmacist, and the lady suggested a day and night cream. Even if you are sensitive to moisturisers/creams, I guarantee that you'd be able to find a brand that you'll be able to use, it's just a matter of how much are you willing to pay.
And no, you're not too young to use anti-wrinkle product. It's a preventive measure, so no one would CARE if you bought some. Also, there are these small little tube things which I think you squeeze on deep lines (some good ones can be really pricey) which I need to get my boyfriend for the wrinkles on his forehead from frowning so much. So yeah, even guys use anti-aging stuff haha.
