Brightening serum with high concentration of vitamin C

COSRX The Vitamin C 13 Serum is an advanced skincare product that effectively combats hyperpigmentation and uneven skin tone thanks to a composition of carefully selected active ingredients. The main ingredient in the formula is 13% ascorbic acid reinforced with a stable derivative of vitamin C (3-0-Ethyl Ascorbic Acid), which together form a powerful brightening complex.

The serum also contains niacinamide and glutathione - ingredients with antioxidant properties that help to lighten hyperpigmentation and protect the skin from premature ageing. The addition of hyaluronic acid ensures adequate hydration and vitamin E protects against free radical damage.

Ingredients you will love:

• Vitamin C (13% ascorbic acid) - a powerful antioxidant that lightens discolouration, stimulates collagen production and protects the skin from photo-ageing.
• 3-0-Ethyl Ascorbic Acid - a stable vitamin C derivative that provides long-lasting brightening and protective effects.
• Niacinamide - strengthens the skin barrier, regulates sebum secretion, has antioxidant, anti-inflammatory and brightening effects.
• Glutathione - a powerful antioxidant that neutralises free radicals, counteracts skin ageing and brightens discolouration.
• Sodium hyaluronate - intensely moisturises, prevents water loss from the epidermis, softens and smooths the skin.
• Vitamin E - protects against oxidative damage, enhances skin elasticity and prevents premature ageing.

Intended use:

COSRX The Vitamin C 13 Brightening Serum is especially recommended for those struggling with uneven skin tone, dull complexion and discolouration of various origins (post-sun, post-inflammatory, hormonal). It is also ideal as part of anti-aging care for those with the first signs of ageing and for those wishing to restore a healthy glow and improve skin texture. The product is suitable for all skin types, but those with very sensitive skin should introduce it gradually due to the high concentration of ascorbic acid.

Directions for use:

After thoroughly cleansing and drying your face, apply a few drops of the serum to your fingertips. Gently massage the product into the face, avoiding the eye area. It is best to apply the serum in the evening, as vitamin C can increase the skin's sensitivity to the sun.

If using in the morning, remember to apply an SPF cream.

For best results, apply regularly for a minimum of 4-6 weeks. Due to the high concentration of vitamin C, those with sensitive skin should start by applying the serum every other day, gradually increasing the frequency.

Tips:

To preserve the activity of the vitamin C, store the serum in a cool, dark place away from direct sunlight. Once opened, it is best used within 6 months. To extend the shelf life of the product, it can be stored in the refrigerator.
