How do I keep myself from getting. Wrinkles?

Aubrey
After getting a really awful sunburn yesterday my eyes opened to the possible wrinkles I will be acquiring. I lifeguarded every summer from age 15-17 and went into a tanning bed 2-3 times a week when I turned 18 for about 3 months. I look at my mom and she's about 48 and looks 40 and she said she was in the sun more but she has an olive complexion and I'm very pale, like I burn at least every other time I go out in the sun. I'm so worried that in gonna get a bunch of wrinkles now... I don't eat a bunch of junk, I eat very little salt/fAt due to heart disease in the family, and I've been on a rerun-a since age 14 for a be... But I do have a pretty significant vitamin d deficiency. What do I do?
