For a nightly pick-me-up, reach for Drunk Elephant T.L.C. Framboos Glycolic Night Serum (£76), which has met wide acclaim in the skin-care community. It contains 10 percent AHAs/BHA — including glycolic, tartaric, lactic, citric, and salicylic — to exfoliate, brighten, and rid the skin of impurities. It also contains sodium hyaluronate crosspolymer, which is the smaller molecule cousin to hyaluronic acid that instantly plumps and reduces lines.
