Don't tan. Outside, or in a tanning bed. Seriously. If you want a little bit of color, there are wonderful self tanning lotions out there-the ones by Jergens and Dove are really good. No, they won't make you a bronze goddess, but you won't look like school paste, either.
If you want to avoid a burn when you go out this summer-wear high SPF sunscreen and sunblock. Use a lip balm with a good SPF in it, and you can also buy face makeup with sunscreens as well.
My mother tanned a lot when she was younger, up until recently, and so did my grandmother. All of that sun damage is REALLLLLY showing up. They have much more wrinkles than women their age who have avoided the sun.
Also, my mother has had to have some skin cancer spots removed on her FACE. The spots look like chicken pox scars now. How attractive is that? She had an swesome tan once upon a time, but now in her 50's she has these small scars on her face...that are going to be there for life-20, 30, or 40+ years depending on her lifespan.
When I was in high school, the cheerleaders and preppy girls were all nice and tan from their sunbathing and regular tanning bed visits. 15 years later, when I run into them somewhere, they look much more haggard, and older than I do. One girl in particular that I went to school with looks like a leather boot now. You should really weigh the pros and cons of looking good NOW vs. having more wrinkles and sun damage later. A 25 year old woman might look great with a tan, but it will rear its head later when she is 40 and her skin looks like she is 60.
ANY amount of sunbathing that you do will effect you later. Any burn you get will affect you later.
