Major Ingredients
Aqua/Water, Ascorbic Acid (23%), Butylene Glycol, Dimethicone, Panthenol, 3-O-Ethyl Ascorbic Acid, Squalane, Sodium Hydroxide, Caffeine, Sodium Hyaluronate, Sodium Metaphosphate, Adenosine, Acetyl Glucosamine, Gardenia Florida Fruit Extract, Allantoin, Dextrin, Tocotrienols, Tocopherol, Elaeis Guineensis (Palm) Oil, Arginine, Niacinamide, Pentylene Glycol, Glutathione, Helianthus Annuus (Sunflower) Seed Oil, Methyl Trimethicone, Carthamus Tinctorius (Safflower) Seed Oil, Camellia Japonica Seed Oil, Daucus Carota Sativa (Carrot) Root Extract, Glycyrrhiza Glabra (Licorice) Root Extract, Beta-CaroteneHow to Use
Step 1: After cleansing and toning, allow your skin to fully dry before applying — Vitamin C is most effective on dry skin. Step 2: Dispense 2–3 drops of the serum onto your fingertips and apply evenly across the entire face and neck, avoiding the eye area. Step 3: Gently pat the serum into the skin with your fingertips until fully absorbed. Do not rub. Step 4: Follow with your moisturizer to lock in the serum and support the skin barrier. Step 5: In the morning, always finish with SPF 30 or higher — Vitamin C and sun protection work together to maximize brightening and anti-aging results. *Pro tip: Avoid mixing with retinol or exfoliating acids (AHA/BHA) in the same routine to prevent irritation. Use Vitamin C in the morning and actives at night. *For external use only. If irritation occurs, discontinue use and consult a dermatologist.Share
