The Cos-IQ 23% Vitamin C Face Serum is a dermatologist-recommended product designed to help you achieve a brighter, more radiant complexion. It contains Ethylated Ascorbic Acid, a highly stable and non-irritating form of Vitamin C, ideal for targeting hyperpigmentation, dullness, and uneven skin tone. With only two active ingredients, this lightweight, non-sticky, fragrance-free serum is gentle enough for all skin types, including sensitive skin, and works well for both men and women.
After using the serum daily for a month, users report a noticeable improvement in skin brightness and a visible reduction in dark spots and pigmentation. The serum’s watery texture ensures it absorbs quickly, making it easy to layer under sunscreen or moisturizer. With consistent use, skin appears clearer, smoother, and more even-toned, without irritation or greasiness. Its minimalist formulation also makes it a great option for people trying to avoid unnecessary additives in their skincare routine.
If you’re looking for an effective, high-strength Vitamin C serum to add to your daily routine, the Cos-IQ 23% Vitamin C Face Serum is a proven choice. It’s especially beneficial for those who want to target dark spots, acne marks, and uneven skin tone. You can purchase it online at the official product page here:
