I have been purchasing this product for over a year now and rely on it to cover acne scars, ruddiness, and acne, which it does VERY well and it's wonderful medium/heavy coverage is definitely its best PRO. Some CONS are that it is extremely difficult to blend perfectly. I use a darker shade that my skin tone because i am ghost white and find that a darker shade gives me a healthier glow, however, this is not a good foundation for that sort of thing because it is hard to blend at the jawline and onto the neck. I also think it may cause me to break out because it is of such heavy consistancy, but until i find another foundation with such great heavy coverage that won't rub off, i'll stick to this one! (btw, if someone DOES know of a foundation that offers heavy coverage, let me know!:)
This stuff is my makeup staple (well, other than mascara). it stays on so much longer than any kohl eyeliner pencil and if you don't mind a very dark black or brown line, it really brings out your eyes.
