Vitamin A has which protective role for the skin?

• A. Protects against UV damage and slows signs of aging
• B. Provides moisture to the skin surface
• C. Reduces inflammation only
• D. Increases production of melanin

Answer: (A)

Vitamin A protects the skin by regulating how skin cells grow and by supporting collagen production, which helps keep the outer barrier strong and capable of repair after UV exposure. Topical forms of Vitamin A (retinoids) increase epidermal turnover and boost dermal collagen, reducing wrinkles and signs of aging while enhancing the skin’s resilience to UV damage. This protective effect goes beyond simply moisturizing or reducing inflammation, and it isn’t about increasing melanin production, which is governed by pigment cells.
