This YEOUTH serum is a 1 fl oz bottle of 99% pure hyaluronic acid in a clean, fragrance-free base. Hyaluronic acid binds up to a thousand times its weight in water — the serum draws moisture into the upper dermis where dehydration lines actually live, so skin reads plumper without a heavy occlusive feel.
Use day and night before moisturizer: a few drops onto damp skin, smooth in, then layer Vitamin C in the morning or retinol at night. The texture is thin and watery so it slips under makeup without pilling, and it works for sensitive skin types that react to thicker creams.
YEOUTH is a cosmetic-chemist-owned skincare brand manufactured in the United States with globally sourced ingredients. Paraben-free, sulfate-free, gluten-free formulation policy across the line.
