When I was a teen, I had bad acne that made me feel very insecure. I would apply benzoyl peroxide and oily-skin moisturizer, then put on CoverBlend foundation and concealer (highly recommend both, BTW heavy yet really natural-looking). This dramatically improved how I looked, so I didn't feel so insecure. When the acne started getting under control in my early-mid twenties, I switched to BP + tinted moisturizer + CB concealer where needed. I eventually dropped the concealer and tinted moisturizer in my mid-20s after my acne had finally completely cleared up and the scars fully healed. Now I just use moisturizer and benzoyl peroxide.
...so I started looking better and stopped wearing makeup as I got older. I'm also a guy. Fail.
