Skin is the body’s largest organ, and its condition reflects overall nutrition more than any single “miracle” food — vitamin C for collagen production, vitamin E and zinc for repair, and the carotenoids that give orange and red produce their colour all play supporting roles. This hub gathers the foods and compounds most relevant to skin health from across the encyclopedia.

Common questions
Do carotenoid-rich foods really affect skin appearance? There’s a genuine, well-documented effect — a diet very high in beta-carotene-rich foods like carrots and sweet potato can temporarily give skin a slightly orange tint (carotenodermia), which is harmless and reverses when intake drops, and is actually used as informal evidence of how directly diet shows up in skin tone.
Does vitamin C help with collagen production? Yes — vitamin C is a required cofactor for the enzymes that build collagen, the structural protein behind skin’s firmness, which is why a vitamin C deficiency, now rare but historically seen in scurvy, causes visibly poor wound healing and skin health.
