Retinol is the chemical name for which vitamin?

• A. Vitamin B
• B. Vitamin D
• C. Vitamin A
• D. Vitamin C

Answer: (C)

Retinol is the chemical name for vitamin A. Vitamin A includes retinol and related compounds such as retinal and retinoic acid, with retinol being the alcohol form commonly used in skincare. In the skin, retinol is gradually converted to retinaldehyde and then to retinoic acid, which helps regulate cell turnover and collagen production, contributing to smoother texture and reduced signs of aging.

Vitamin A is fat-soluble and essential for vision and overall health. In skincare, retinoids derived from vitamin A can improve fine lines and pigmentation, but they can cause irritation at first, so it’s wise to start with a lower concentration and use them at night, paired with daytime sunscreen. Other vitamins like B, D, and C are different nutrients with distinct roles, which is why retinol is specifically associated with vitamin A.
