Retinol is commonly known as which vitamin?

1. Vitamin C

2. Vitamin B

3. Vitamin A

4. Vitamin D

The correct answer is: Vitamin A

Retinol is commonly known as Vitamin A, which is crucial for various bodily functions, particularly in maintaining healthy skin. As a powerful antioxidant, retinol plays a vital role in promoting skin cell turnover and stimulating collagen production. This can help reduce the appearance of fine lines, wrinkles, and uneven skin tone, making it an essential ingredient in many skincare products aimed at improving skin texture and overall appearance. Vitamin A, in its various forms, is also important for vision, immune function, and cellular communication. In the context of esthetics, the knowledge of retinol as Vitamin A is fundamental, as it allows estheticians to recommend appropriate treatments and products to clients based on their skincare needs. Understanding the significance of Vitamin A in skin health helps practitioners educate clients on how regular use of retinol can lead to longer-term skin benefits, further enhancing their professional credibility and effectiveness.
