COSRX Advanced The Vitamin C 23 Serum

What skin types can safely use COSRX Advanced The Vitamin C 23 Serum?

This serum works best for normal, dry, and oily skin types that have prior experience with vitamin C.

How does pure vitamin C improve uneven skin tone and dark spots?

Pure ascorbic acid neutralizes free radicals and inhibits excess melanin production to fade hyperpigmentation and reveal a clearer complexion.

Why is super vitamin E included in this formula?

Vitamin E works synergistically with vitamin C to boost antioxidant protection and stimulate collagen synthesis.

How should you store this high-potency serum after opening?

Keep the bottle stored in the refrigerator to preserve the integrity of the active ingredients and prevent rapid oxidation.

Can you use this serum during your morning skincare routine?

Yes, apply it in the morning followed strictly by a high-protection sunscreen to shield your freshly treated skin from UV damage.

What makes this specific serum different from lower-strength vitamin C products?

The 23 percent concentration delivers faster, more intensive results for experienced users targeting stubborn blemishes and deep fine lines.
