About COSRX Advanced The Vitamin C 23 Serum
If your skin feels dull, looks uneven, or is showing the first signs of aging, meet your new brightening hero. COSRX Advanced The Vitamin C 23 Serum is a high-strength yet gentle formula designed to restore your natural glow. With 23% pure vitamin C (ascorbic acid), this advanced serum works to fade dark spots, smooth rough texture, and protect against daily environmental stress.
But that's not all. This advanced the vitamin C serum combines powerful 23% vitamin C with super vitamin E and glutathione two trusted antioxidants that boost luminosity and defend your skin like a shield. To keep your skin happy and hydrated, the formula also includes panthenol, allantoin, and hyaluronic acid. These soothing ingredients lock in moisture and reduce irritation, making COSRX Advanced The Vitamin C 23 Serum suitable even for those new to higher-concentration vitamin C (though we always recommend a patch test first).
The texture? Smooth, lightweight, and fast-absorbing. It glides onto your skin without sticky residue, leaving it feeling plump, fresh, and visibly brighter from the very first use. With consistent use, you'll notice your complexion becoming more even, radiant, and youthful.
For best results, pair it with sunscreen during the day vitamin C boosts sun protection, but it's not a replacement for SPF.

As soon as you apply the patches under your eyes you feel an instant cooling refreshing effect. When you remove them you clearly see a difference and have a fresh look. When you feel you need a little refresh just repeat.

Early days but pleased
I have only used the combo for a short time but I do like the products. I prefer products that are holistic without a lot of chemicals. As an older lady I have the lines of life’s experiences and I do sense a softening of upper lip lines so I look forward to further improvement.

Light as air…
Love this sunscreen…I forget that I have it on. No sticky feeling and no stinging as I also cover my eyes with it. Also no smell. Those were three major issues I have had with so many of the other North American or European sunscreens I have used in the past. This is my first time trying Korean products - I am impressed!

This stuff is amazing!! Truly weightless and undetectable on the skin, glides over makeup effortlessly. Not greasy or sticky at all -I actually question whether it’s even been applied! Love it!
