flex89 saidYou COULD go tan in a bed, but you still have the skin cancer risk.
But let's be honest, it takes a hell of a lot more than a half hour every day in the sun to cause cancer, jesus.
What a total falsehood. I
have had skin cancer - melanoma, no less - and I didn't get so much as ten minutes a day even before the docs diagnosed me, even though I've worn sunscreen virtually everyday since childhood (my mom being a dermatologist).
It varies by person. Your skin's natural melatonin levels affects the matter, and the sun exposure you had when you were newborn to 3-ish (I forget the upper bound) is another important criteria.
Anyway, back to the question, the oils that people are suggesting really just mask the appearance by softening and moisturizing the skin. Prescription retinoids will help the appearance a little. Your best treatment option is lasers, which obviously is pricey and won't make them go away altogether.
edit1: i said retinols, i meant retinoids. whatever, just ask for retin-a, that stuff they also use for acne. it'll work by promoting new collagen production.
