Olivanna’s Vitamin C Brightening Day Serum uses 3% vitamin C (Ascorbyl Tetraisopalmitate) to visibly boost radiance and promote a more even-looking tone while hyaluronic acid, squalane, glycerin, and ceramides deliver lasting hydration and help reduce moisture loss. Fast-absorbing and lightweight, it smooths the look of texture, supports softer, more supple skin, and helps shield against daily environmental stress and UV-related damage for a fresh, luminous finish. Cornflower and chamomile extracts help keep skin feeling calm and comfortable, and the vegan, cruelty-free formula layers easily under moisturizer or wears well on its own for a hydrated, refreshed look through the day.
