I’ve been using this serum for years, and it’s still my go-to for that fresh, radiant glow. Its creamy texture absorbs quickly, perfect under makeup, and leaves my skin looking brighter and more even. Dark spots? Fading. Dullness? Gone. Plus, the light citrus scent is a refreshing bonus to my morning routine. Yes, it’s a splurge, but the results speak for themselves. If you’re ready for a serious TyChi · sephora.com
