COSRX The Vitamin C 13 Serum 20ml (0.67 fl oz)
CosRX The Vitamin C13 Super Vitamin E & Hyaluronic Acid Serum (20ml) is a lightweight, gentle Vitamin C serum with a watery texture which enhances skin condition and evens out skin tone. Suitable for daily use on sensitive skin, regular use of this serum will fade blemishes, dark spots and freckles and improve overall tone. Providing daily brightening care with a 120-hour antioxidant effect, the serum refines skin texture and reduces the size of pores. Formulated with 13% Pure Vitamin C in the form of Ascorbic Acid, it minimises the appearance of fine lines and wrinkles, improves discolouration and enhances skin tone. Hyaluronic Acid optimises hydration levels whilst Allantoin soothes and protects the skin, relieving irritation. Vitamin E augments the antioxidant effect. Cruelty-free & vegan-friendly. Directions of use: Cleanse your skin and use a toner. Then apply a few drops of serum to the skin. Use fingertips to gently massage and absorb the serum, starting from the inside of the face and working towards the edges.
