Vitamin A derivatives, also known as retinoids, are compounds derived from vitamin A that play a crucial role in skin health and vision. They are commonly used in skincare products to promote cell turnover, reduce wrinkles, and treat acne. Some well-known retinoids include retinol, retinaldehyde, and tretinoin. These derivatives work by binding to specific receptors in skin cells, enhancing their function and encouraging the production of new cells. This process helps improve skin texture and tone while also supporting the body's immune system and vision. Regular use of vitamin A derivatives can lead to healthier, more youthful-looking skin.
