Pro-retinol A, also known as retinol or vitamin A, is a derivative of vitamin A that is commonly used in skincare products for its anti-aging and skin-renewing properties. It promotes cell turnover, helps improve skin texture, reduces the appearance of fine lines and wrinkles, and can aid in the treatment of acne. Unlike stronger retinoids, pro-retinol A is typically milder and may be better tolerated by sensitive skin.
