Cosrx vitamin c serum

You choose based on your skin goals, sensitivity, and hydration needs. For extra hydration and brightening, pick the Cosrx Vitamin C 23% Serum with Vitamin E & Hyaluronic Acid. If you prefer a lighter, more straightforward vitamin C option, go with Cosrx Vitamin C23 Serum. Start slow if you have sensitive skin—every other day—and always finish with sunscreen in the morning.

It combines a high 23% ascorbic acid dose with stabilizing Vitamin E and hydrating Hyaluronic Acid. This pairing boosts brightening and antioxidant protection while supporting a hydrated skin barrier. The high concentration can irritate sensitive skin, so patch testing and gradual introduction are advised. Use in the daytime after cleansing, then follow with moisturizer and SPF.

Begginners should start cautiously, while experienced users may integrate it into a daily routine. For a beginner, patch test, apply a small amount every other day for the first week, and use sunscreen. As tolerance builds, increase frequency slowly and observe how your skin responds. For a pro routine, daily use is common, with careful layering under moisturizer and sunscreen while monitoring for irritation.

Store Cosrx vitamin c serum in a cool, dark place and keep the bottle tightly closed. Patch test before full use and avoid contact with eyes; apply after cleansing and before moisturizer. If you use other actives, consider alternating days or applying them at different times to minimize irritation. Always wear sunscreen during the day, as vitamin C can increase sun sensitivity.
