"The key to glowy skin year-round is regular gentle exfoliation. To get my there, I've been using the PCA Skin Resurfacing Serum ($99), which contains a blend of AHAs and PHAs to melt away dead skin cells and congested pores and prickly pear flower extract to support your skin's moisture barrier. This magic combination has left my skin looking radiant without any discomfort. I use it regularly in my skin cycling routine." — JH
