The Claim
Some people think that taking large amounts of vitamin A will lead to better skin health and appearance.
Origin
This belief is often propagated by beauty and skincare marketing that emphasizes vitamin A's role in cell turnover and skin maintenance.
What Science Says
While vitamin A is important for skin health, excessive intake can lead to toxicity, with symptoms including skin irritation. Studies show that moderate intake supports skin health, but higher doses do not confer additional benefits and may cause harm. Topical forms of vitamin A (like retinoids) are effective, but oral supplementation beyond the recommended daily allowance is not advised for skin improvements.
