Evologie Intensive Blemish Serum
"I am beyond obsessed with Evologie's blemish serum. Last summer, I had a series of uncomfortable cystic breakouts that failed to respond to any topical treatment I used—except this miracle serum. It penetrates skin deeply yet gently, and you notice results overnight."—Cristina Velocci, Deputy Editor
