Does your makeup barely last until lunchtime? These hot summer days can leave skin feeling like an oil slick, which can quickly “melt” off your makeup and even ensue a surge of breakouts. To prevent such, I like to apply the oil-, color- and fragrance-free B. Kamins Corrective Mattifier to my t-zone in the morning before putting on makeup. This treatment works to reduce sebum production, and also prevents further breakouts with salicylic acid. It also contains silicones, which fill in any large pores and allow your foundation to glide on super smooth. You’ll notice a shine-free, matte finish, and makeup touch-ups are fewer and farther between—if necessary at all.
