I seen girl really u close and they have no bumps on their face and they look as if they never had pimples. I have ance scar and when I wear foundation you can still see bumps. So, how do those girl so that?
They take care of their skin. Wash their face, moisturize, drink plenty of water. Or see a dermotologist to clear the acne. Get a different foundation and when you apply it, don't rub it into your skin. Dab it on/ press it into your skin with a foundation brush or makeup sponge.
Part of it is genetics, and part of it is how much they care for their face. I used to have a bad acne issue and tried so many face washes and none of them worked. Now I use an anti-bacterial facial soap, and every single time I use it, my face is noticeably better. :) Moisturizing helps also.
