Undecided Question

True beauty lies within, but still….?

I know I'm ok looking, and when I look in the mirror it's fine, but whenever I take pictures of myself all I see is my flaws and I really hate taking pictures of myself.
The biggest reason is that I used to have really good skin, and recently it's been breaking out a lot on my forehead and I can't do anything about it. It's frustrating because I'm in my late teens and most everyone I know is way past the acne stage. There are other flaws too but my skin is what gets me down the most because it didn't used to be that way.
I just feel really insecure and although I know in my head not to worry/think so much about myself, but when I take pictures it just gets me down again.

How can I feel better about the way I look?
