1. Cleanse your face thoroughly and pat dry.
2. Apply a small amount of serum to your face and neck.
3. Gently massage it in with your fingertips until absorbed.
4. Wait a few minutes before applying your moisturizer.
5. Using the serum in the day? Always finish with sunscreen.
6. Start with two to three times a week and build up to daily use if your skin tolerates it.

If your skin feels tight after the serum, the Advanced Snail 96 Mucin Power Essence helps restore moisture. Apply the essence before the serum or combine it with a rich moisturizer for extra hydration.

Your complexion evens out and pigment spots fade noticeably. Vitamin C slows pigment production in your skin while protecting against environmental damage. At 23%, the concentration is high enough to tackle even stubborn spots. Niacinamide boosts this effect and helps your skin feel firmer. The formula also includes hyaluronic acid, so your skin won’t dry out during use. If you’re looking for a COSRX product that truly makes a difference, this is one of the strongest choices in the range.

It depends on how sensitive your skin is. At 23% vitamin C, you might experience tingling or redness initially, especially if your skin isn’t used to strong actives. Start with twice a week and increase gradually. Find 23% too intense? The COSRX Vitamin C 13 Serum is a milder option with less risk of irritation but slower results on stubborn spots. Never use this serum on the same day as strong exfoliants or Retinol, as that greatly increases irritation risk.

Store the serum in a cool, dark place, preferably in the fridge. Vitamin C oxidises quickly when exposed to light, air, and heat. If the serum turns yellow or orange, it’s oxidised and less effective. Always close the cap tightly after use and preferably use the serum within three months of opening.

Apply the serum to a clean, dry face before your moisturizer. Don’t use it the same day as Retinol or exfoliating acids like AHA or BHA, as that increases irritation risk. If you want to use both, apply vitamin C in the morning and Retinol or the AHA 7 Whitehead Power Liquid Exfoliant at night. Always wear sunscreen during the day, as vitamin C makes your skin more sensitive to the sun.

If you’re new to vitamin C or have sensitive skin, the 13% variant is a safer start. It causes less irritation and is easier to tolerate daily. Have you used vitamin C serums before and want quicker results for dark spots or a dull complexion? Then the COSRX Advanced The Vitamin C 23 Serum - 20ml is the stronger choice. The higher concentration works faster on stubborn pigment spots. Want to buy COSRX Vitamin C 23 serum but unsure which strength suits you? Start with 13% if your skin reacts sensitively to new products.
