This obsessed-over serum from top NYC aesthetician Sofie Pavitt exfoliates, clarifies, and hydrates. Pavitt, who specializes in problem skin, is famous for a no-nonsense approach inspired by frequent trips to Seoul. She designed the serum to seriously boost any skin type—and it’s especially amazing for blemish-prone, dull, or uneven skin. Mandelic acid gently exfoliates and smooths, hyaluronic acid hydrates, and panthenol protects. And it’s gentle enough to use daily: Apply three pumps over the face and neck after cleanser and toner, then follow with moisturizer and SPF for fantastic—brighter-looking, smoother, softer—results.Pavitt’s tip: “Alternate your active ingredients. If you use retinol at night, use the mandelic serum in the morning to supercharge your results.”1 fl oz / 30ml
