Vitamin A is an essential nutrient to maintain our health. When it comes to skincare, retinoids are a type of vitamin A, and topical application of various retinoids can help treat acne, improve fine lines and wrinkles, as well as reduce hyperpigmentation, signs of UV damage and inflammation. The most commonly used topical retinoid is retinol, but retinaldehyde, retinoic acid and retinyl palmitate are also regularly seen within skincare.
