Hope I can help you here:) but I've used this product for 3 years now and from what I've heard and seen, this is the HG of primers in my book. It claims to be perfect for ALL skin types, I have a friend who has such dry and oily skin and one night I lent her the product while we were going out dancing and she was floored with how great her makeup stayed intact without patchy marks. From what I've experienced, this primer not only keeps everything in place, but it also has a smooth lightweight finish, mattifies your skin and the most important, NO PORES:) Unfortunately it isn't a concealer because it's mainly used for keeping makeup in place. Again, the primer works for ALL skin types of all different tones, and I hope when you try it, it'll work wonders:) Hope this helped!
