Why you’ll love it: Who knew retinol could be so gentle? Boscia’s is strong enough to diminish dark spots without irritating even sensitive editors’ skin. It’s also loaded with vitamin C and bakuchiol, and together these star ingredients offer a tried-and-true way to smooth lines and even out skin texture, all while making skin brighter and more radiant. How you’ll use it: After cleansing, massage three or four drops onto your face (and neck and chest, if you’d like) at night. To avoid irritation, start off using it once or twice a week and work your way up. Another thing you can do is top it with a basic moisturizer. Avoid this—and any retinol— if you are pregnant or nursing.
