Vitamin A is a powerful skincare ingredient. While it is often referred to interchangeably as retinol, there are actually two types of Vitamin A. The first type, retinoids, stimulate the production of new skin cells and are effective at treating acne and fighting wrinkles. The second, carotenoids, are high in antioxidants and can prevent cell damage, premature skin aging, and other diseases. You can get this type of Vitamin A from your diet by eating foods such as carrots, apricots, and squash.
