What's a good daily vitamin to take if I'm 13?!

I don't exactly eat the healthiest so I don't get my daily vitamins. I would also like to get one that helps the skin, and my brother pointed out that I should get daily vitamins to help my skin (you know since if you don't get enough sleep and/or you don't eat everything you get bags or slight wrinkles around your eyes), so I would really like to get a daily vitamin to help. But when we were learning about drugs in school, I learned that there are some brands that used drugs (which is why I didn't take the daily vitamins my mother got me some years ago kinda got wasted because we bought them, but I was afraid they had drugs in them, so yeah that money kinda went down the drain).

But I just want to know of a good daily vitamin brand that helps the skin, but doesn't have drugs in it.

Thanks for answering and have a great day!
