Designed for daily use, this gentle water-based serum combines 13% pure vitamin C with barrier-supporting hydrators to deliver visible brightening without irritation. Its lightweight, non-sticky formula absorbs quickly and leaves skin feeling smooth and refreshed. Regular use targets dullness, uneven tone, early signs of aging, and hyperpigmentation caused by sun damage or post-acne marks.
Enhanced with Tocotrienol (Super Vitamin E) for potent antioxidant defense, the formula also includes Niacinamide and Licorice Root Extract to even out skin tone, while Sodium Hyaluronate, Panthenol, and Allantoin help retain moisture and soothe sensitivity. The serum’s slight yellow tint signals the presence of pure vitamin C and its freshness.
