CosRx The Vitamin C 23 Super Vitamin E & Hyaluronic Acid Serum 20g

This serum is formulated to brighten the complexion, reduce the appearance of wrinkles and pigmentation, and improve skin tone and texture. It also addresses acne scars and hyperpigmentation while being gentle and non-irritating.

After cleansing and toning, apply 2–3 drops of the serum to the entire face. Gently pat for better absorption. Follow with a moisturizer and, during the day, apply sunscreen. Avoid mixing with retinol or acids in the same routine.

The serum contains 23% pure Vitamin C for brightening and anti-aging benefits, Super Vitamin E (Tocotrienol) to stimulate collagen production, Hyaluronic Acid to maximize moisture retention, and Allantoin to soothe and relieve irritation.

While the serum is formulated to be gentle, it contains a high concentration of Vitamin C, which may cause sensitivity in some individuals. It's recommended to perform a patch test before full application and consult with a dermatologist if you have concerns.

To preserve the serum's potency, store it in the refrigerator and use it within two months of opening. This helps prevent oxidation and maintains the effectiveness of the Vitamin C.

It's advisable to avoid using this serum in the same routine with retinol or other acids to prevent potential irritation. If you wish to incorporate multiple active ingredients, consider using them at different times of the day or on alternate days.

The serum has a lightweight, watery texture that absorbs quickly into the skin. Some users have reported a strong scent upon application, but it typically dissipates quickly.

Yes, this serum is both cruelty-free and vegan-friendly, aligning with ethical skincare practices.
