FAQ
Is the Cosrx Vitamin C 13 Serum good for sensitive skin?
This serum is formulated with centella asiatica and panthenol to soothe skin, but the 13% L-Ascorbic Acid can be potent. If you have sensitive skin, perform a patch test and consider starting with use every other day to build tolerance for your brightening skincare routine.
Can I use this Vitamin C serum with niacinamide?Yes, absolutely. This serum is expertly formulated with both L-Ascorbic Acid and niacinamide to work in synergy, enhancing brightening and antioxidant benefits while minimizing potential irritation, making it a powerful anti-aging serum.
How should I store my Cosrx Vitamin C 13 serum to prevent oxidation?To maintain the potency of this stable vitamin C serum, store it in a cool, dark place away from direct sunlight and heat. Keeping it in its original opaque bottle in a cupboard is ideal to protect its antioxidant properties.
When will I see results from using this dark spot corrector?With consistent daily use, you may notice an improvement in overall radiance within a few weeks. Significant dark spot reduction and even toning typically become more visible after 8-12 weeks of continued use.
Should I use this serum in my AM or PM skincare routine?This serum is designed for morning skincare use. Applying Vitamin C in the morning helps neutralize free radicals from UV exposure and pollution throughout the day. Always follow with sunscreen for maximum protection.

Products NOT to use with
-
Other high-potency L-Ascorbic Acid serums (e.g., SkinCeuticals C E Ferulic)
-
Exfoliating Acid Toners (e.g., PIXI Glow Tonic – Glycolic Acid, Paula’s Choice Skin Perfecting 2% BHA Liquid Exfoliant – Salicylic Acid) [Note: It’s best to use these on alternate nights, not simultaneously].
-
Direct acids like AHAs/BHAs in high concentrations (e.g., The Ordinary AHA 30% + BHA 2% Peeling Solution)
Ingredients NOT to use with
-
Niacinamide + Strong Direct Acids (e.g., Glycolic Acid, Lactic Acid, Citric Acid, Salicylic Acid): Using them together at a very low pH can cause flushing and irritation for some. It is safer to separate their use (AM/PM).
-
Pure Vitamin C (L-Ascorbic Acid) + Pure Niacinamide: This is an outdated concern. Modern formulations have shown they can be stable and effective together, as proven by this very product. The key is the specific formulation and pH level.
-
Vitamin C + Retinol: They are most effective at different pH levels and can be irritating when applied simultaneously. Use Vitamin C in the morning and retinol at night.
