To camouflage an acne mark that is red, your best bet is to mix two concealers–one that matches your skin tone and one that’s about one or two shades darker. Use a foundation or concealer brush to tap the concoction over the scars and make sure to blend, blend, blend so that your color-correcting looks natural. And if you’re mark is really red, look for a concealer with a yellow undertone (try Kryolan UltraFoundation in Yellow Veil). Yellow counteracts the pink in your scar. For marks that are raised or textured, stick to matte powders.
