COSRX The Vitamin C 23 Serum

If your natural skin tone is dark, it looks dull, so you might be hesitant about using whitening products. As someone with sensitive skin like me, I couldn't even dare to try them, but after using the milder shade 21, I switched to shade 23.

Some people say their skin breaks out when they apply vitamin products... but it’s not because it doesn’t suit you; it’s just part of the skin's regeneration process. After about a week, it calms down again, and I feel like my skin becomes brighter.

A stinging sensation does not mean it is not working.

Start with shade 21~ Trust me and give it a try.

And if possible, please use it only at night.
