Owning a different face product for every season is convenient — but expensive. In the summer months, foundation can start to feel too heavy. Switching out for a brand-name tinted moisturizer is one option, but mixing up your own concoction is another. By combining equal parts face lotion and foundation, you can create the perfect solution: A DIY tinted moisturizer. If your face is naturally oily, cut back on the lotion. If your skin is dry or combo, this is a great option. Enjoy!
