In my teens and early 20's, I loved nothing more than a deep bronze sun tan. I'd hit up the solarium every week and sunbake for hours in the backyard, often with little or no SPF. Just writing that makes me feel ill. I have biiiig regrets about that behaviour, and I drastically improved my habits luckily while I was still in my early 20s.
At 27, I now wear sunscreen every day, lecture my friends for their sun seeking habits during summer, and only use fake tan.
I'd be lying if I said I didn't miss that natural tan I used to build up in summer. Fake tanning is a pain in the butt. It's time consuming, stains your sheets, and it stinks...usually.
