How do I apply natural make-up to bad skin?

I have some scars on my face from picking my pimples, I also have some small red blemishes most of the time. I find when I put on make-up it gets oily in the forehead region, and the redness begins to show after an hour.





I usually: I first put the foundation on most of my face (extra on the bad areas), and then use covergirl powder in oily regions (nose, forehead).

Use Maybelline Pure Concealer Blemish Treatment Stick to cover any blemishes. Spread E.l.f. Shielding Hydro-Tint SPF 15 on fingertips and then apply to face, finish with Physicians Formula Powder Palette Multi-Colored Face Powder in Translucent. Curl eyelashes with Revlon Expert Effect Lash Curler and use Rimmel Extra Super Lash Mascara in Black-black. For lips, use E.l.f. Luscious Liquid Lipstick.
