Has the summer heat been making your makeup look worn-in just after 15 minutes? Then let us find the right solution for you. To withstand the sweltering summer heat, your best bet is to use mattifying formulas and long-wear products. Start with a grippy primer to hold your base in place and go in with a matte foundation. This will keep your foundation from looking too greasy. Follow up with the rest of the steps and use a matte setting powder or a setting spray to lock everything in place.
