Blush for Acne Prone Skin
Tarte Amazonian Clay 12-Hour blush is great for acne prone skin. The clay minimizes oil to balance skin and keep product in place. It comes in a great bunch of colors so you can choose the one that looks best with your skin tone. Best of all, it is a natural product (has the Sephora Natural Seal) so it is good for your skin. Comes in a cute compact too!
Well I have acne prone skin, and blushes that I use haven't broken me out, but I don't wear blush on a day to day basis. But I would recommend Clinique's Blushing Blush Powder Blush in Iced Lotus. It is a very soft build-able pink color. If you don't want to bring out pinks in your skin, I would recommend bronzer. It brings warmth to your face without making it look like you are flushing.
I know what you mean when you say blush brings out acne marks. NARS blushes have that effect on me. However, I like Everyday Minerals for their blushes. A lot of interesting colors to try and like their foundations, no bismuth and animal cruelty free! Good luck in finding your perfect blush!
Clinique Soft-Pressed Powder Blush is a soft, sheer, natural-looking powder blush that gives your cheeks a radiant glow and a silky fresh finish. From subtle to vibrant, a wide range of shades allow you to create multiple looks. This blush is non-acnegenic so it won't cause you to break out and you can find it here: http://www.sephora.com/browse/product.jhtml;jsessi
I hope this helps you.
