Vitamin C serum is a powerful skincare essential known for brightening the complexion, reducing dark spots, and boosting overall radiance. Its antioxidant properties help protect the skin from environmental damage, support collagen production, and promote a firmer, more youthful appearance. For best results, apply a few drops of the serum to clean, dry skin—preferably in the morning—before moisturizer and sunscreen. Gently massage it into the face and neck, allowing it to absorb fully. With consistent use, Vitamin C serum can transform dull, tired skin into a glowing, even-toned, and refreshed complexion.
