It's a No for me. The effaclar Mat from La Roche-Posay promises anti-glare, works against visible pores and better skin quality. So it would: leave no greasy film, instantly matte the skin, close the pores and make the pores less visible. After multiple uses, it would further mattify your skin... I have this tube empty now and I am very dissatisfied. Anything the product promises doesn't do it for me. When you apply it, it leaves a fat layer. My skin is going to shine tremendously. Your pores become more visible by the film layer it leaves behind. And when you use makeup over it, your makeup will smear because of the oily structure. It's a pity. Does anyone have any tips on how to properly care for oily skin that you can use during the day under your makeup and that doesn't leave a film layer behind?
