Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Beta-carotene is a precursor to vitamin A (retinol), an essential nutrient known for its role in maintaining healthy skin. Scientific studies have shown that beta-carotene, due to its antioxidant properties, can help protect the skin from oxidative stress caused by UV radiation and environmental pollutants. Antioxidants like beta-carotene neutralize free radicals, which can otherwise accelerate skin aging and contribute to the development of skin disorders.

Oral supplementation or dietary intake of beta-carotene may contribute to photoprotection, reducing skin redness (erythema) and damage following UV exposure. Several clinical trials have demonstrated modest improvements in skin appearance and resilience after consistent beta-carotene supplementation. However, the effect size is generally moderate compared to topical sunscreens or direct vitamin A derivatives (retinoids).

Historically, populations with diets rich in carotenoid-containing fruits and vegetables tend to have healthier skin, which further supports the rationale for its use. Despite these benefits, excessive beta-carotene supplementation, particularly in smokers, has been associated with adverse health outcomes, so moderation is advised. Overall, while beta-carotene is not a miracle solution for skin care, there is reasonable scientific evidence for its supportive role in maintaining skin health and offering some protection against environmental damage.
