Vitamin C Serum || COSRX Vitamin C 13 Serum 20ml

Cosrx Vitamin C 13 Serum 20ml is a daily brightening serum formulated with 13 % pure Vitamin C (ascorbic acid) to help improve dullness, fade dark spots, and even out skin tone while giving your skin a radiant glow. This lightweight formula absorbs quickly into the skin with a non-sticky finish, making it easy to layer under moisturizers or sunscreen in both morning and evening routines.

Vitamin C is one of the most effective antioxidants for skin. In this serum, it works to help reduce visible signs of hyperpigmentation and uneven tone caused by sun exposure, acne marks, or aging. Over time, consistent use can help brighten the complexion and support a healthier overall look. Alongside Vitamin C, the formula includes hyaluronic acid and panthenol to keep skin hydrated and comfortable throughout the day.

How It Helps Skin Look Brighter

This serum targets common concerns like dullness and dark spots, helping skin look more even and luminous. The combination of antioxidant Vitamin C and supportive nourishing ingredients helps protect your skin against environmental stressors and free radicals. With regular use, skin can appear smoother and more uniform in tone.

Because it has a gentle yet effective concentration of Vitamin C, this serum suits most skin types, including sensitive skin, when introduced gradually. Many users find it suitable for daily use since the formula feels light and refreshing rather than heavy or greasy.

Easy to Include in Your Routine

This serum layers well with other skincare products. After cleansing and toning, apply a few drops to dry skin. Gently pat or smooth it in until fully absorbed. Follow with your favorite moisturizer and, especially during the day, broad-spectrum sunscreen to protect your skin from UV damage and maintain brightening benefits.

You can use it every morning or night, but applying it in the morning often helps boost antioxidant protection throughout the day. Always do a patch test if you have especially sensitive skin and start with alternate-day use to build tolerance.
