The Vitamin C 13 Serum is a powerful brightening treatment that revitalizes dull and uneven skin tones. Formulated with 13% pure Vitamin C (Ascorbic Acid), this serum works to diminish dark spots, acne scars, and hyperpigmentation while promoting a radiant, even complexion. The addition of Niacinamide enhances the brightening effects, balancing oil production and improving skin texture. With hydrating Sodium Hyaluronate and soothing Panthenol, this lightweight formula ensures skin remains moisturized and calm. Ideal for those seeking a luminous glow and a smoother skin surface.

Apply a few drops to cleansed and toned skin, avoiding the eye area. Follow with a moisturizer and sunscreen during the day. Use in the morning or evening as needed.
