COSRX Vitamin C 13 Serum

Highly concentrated serum with pure vitamin C for shiny and radiant skin and an even complexion!

Numerous consumer reviews of vitamin C show that it often leads to irritation and burning, and many with sensitive skin have had to stop using it.

In response, COSRX studied many research papers and conducted their own research to finally develop a concentrated vitamin C serum with maximum efficacy and minimal potential for irritation.

Vitamin C Serum 23 is formulated with 23% pure vitamin C to fade acne scars and brighten dull, dull, tired skin. It also improves uneven skin tone leaving the complexion clean and healthy.

It is known that highly concentrated vitamin C serums are difficult to produce because they are subject to oxidation caused by external conditions and are prone to explosion due to internal gas formation. To prevent this, COSRX developed a specialized method that allows gas to be expelled from the reservoir while simultaneously blocking oxygen from entering the reservoir to safely house the highly concentrated formula of pure vitamin C. The serum also boasts a two-layer structure with an oil layer on top that maintains freshness and delays oxidation. COSRX claims "We provide a stable formula, with minimal irritation, but maximum effectiveness of vitamin C!"
