YEOUTH Hyaluronic Acid + Vitamin C Serum is a 1 fl oz dropper bottle that pairs the two most-cited active ingredients in morning skincare into a single formula. Hyaluronic acid pulls moisture into the upper dermis; Vitamin C targets the look of dull spots, dullness, and uneven tone — together they handle hydration and brightening in one step.
Use as the morning serum on clean damp skin before sunscreen. Layers cleanly without pilling. Distinct from the brand’s pure HA serum (which is 99% hyaluronic acid) and the standalone Vitamin C serum — this one is built for shoppers who want both functions in one bottle.
YEOUTH is a cosmetic-chemist-owned skincare brand manufactured in the United States with globally sourced ingredients. The whole line is paraben-free, sulfate-free, gluten-free, and never tested on animals.
