Retinoids are a group of compounds derived from Vitamin A. They are commonly used in skin care products because they have the ability to help treat a multitude of skin conditions such as acne, wrinkles, and sun damage. The most popular forms of retinoids used in cosmetics are Retinol and Retinaldehyde. Retinoids work to speed up cell turnover and boost collagen production, resulting in smoother, brighter, and healthier looking skin. A well-formulated retinoid product can reduce fine wrinkles, even out skin tone, reduce hyperpigmentation, reverse sun damage, improve skin texture, and shrink the overall appearance of pores. Retinoids also have anti-inflammatory and anti-bacterial properties, making them an excellent choice for fighting acne.
