A night retinol cream is a skincare product containing retinol, a form of Vitamin A. It works by accelerating skin cell renewal, which helps to unclog pores, fade dark spots, and boost collagen production. Using it at night is essential because retinol can make the skin more sensitive to sunlight. With consistent use, it effectively reduces the appearance of fine lines, wrinkles, and acne, resulting in smoother and more even-toned skin.
