Give dull, tired skin a daily dose of radiance with this antioxidant-rich vitamin C serum. Formulated with pure ascorbic acid alongside a stable vitamin C derivative, it helps brighten the complexion, fade the appearance of post-acne marks and pigmentation, and promote a more even skin tone.

Centella asiatica, sodium hyaluronate, and a blend of soothing botanical extracts help keep skin hydrated and comfortable, while green tea, peony, lotus, broccoli, and grapefruit extracts provide antioxidant protection against environmental stressors. A combination of amino acids and skin-conditioning peptides supports a smoother, firmer-looking complexion, making this serum an excellent addition to any well-aging routine.

Lightweight and fast-absorbing, it layers easily under moisturizer and sunscreen, leaving skin looking brighter, fresher, and more luminous with continued use.

With 5% pure vitamin C, this serum is ideal for beginners and those with sensitive skin who want to brighten dullness, improve the appearance of pigmentation and post-acne marks, and achieve a more even-looking complexion without the intensity of higher-strength formulas.

After cleansing, apply about half a drop to the face and gently massage into the skin. For those with sensitive skin, use after toner and apply 3-4 drops. For those with extra sensitive skin, mix a few drops into serum or lotion before applying to face.
