Re: Concealer for redness (Teenage acne)[ Edited ]
There's too many choices now, I lived in the drugstore for concealer growing up, there was a good one part green, part color that I would mix (green covers red)
If you aren't aware, concealer goes under powder foundation, the powder helps set it.
A current drugstore brand I've used lately is Physician's Formula Conceal Rx™ Physicians Strength Concealer. I've put it on just the acne and it does stay on my oily/combo skin and covers red..and every concern.
Re: Concealer for redness (Teenage acne)
If you're looking for a heavy-duty, high-coverage concealer, I would definitely recommend Make Up For Ever's Full Cover Concealer. It is waterproof, doesn't cake, stays all day and completely hides the redness.
I use both this and the Cle de Peau Beaute Concealer depending on what I need to cover up, but the MUFE one is by far my favorite.
