Beta-Carotene
Ingredient Info
Beta-carotene is a natural orange pigment found in plants that your body can convert to vitamin A. In skincare, it acts as an antioxidant to help protect skin from damage caused by free radicals and UV exposure.
Benefits
- Antioxidant protection against free radicals linked to skin aging
- May help defend against UV-related skin damage when used alongside sunscreen
- Supports skin's natural defense systems against oxidative stress
Potential concerns
- Oral supplements at high doses (30 mg+) showed no measurable benefit in preventing skin aging over 4.5 years in clinical trials
- Topical application evidence is limited; most research focuses on dietary intake or oral supplements
Science: Beta-carotene is recognized as one of skin's natural antioxidant defense compounds alongside vitamins C and E. However, a large randomized controlled trial found that oral beta-carotene supplementation (30 mg daily) did not slow skin aging compared to placebo, suggesting topical application may have limited practical benefit for photoaging prevention.
