Beta-carotene, a precursor to vitamin A (retinol), has been investigated for its potential skin benefits, including its role in supporting or treating wrinkles. The justification for its use is primarily scientific, although the strength of evidence is moderate and not definitive. Several studies have explored the effects of beta-carotene supplementation or topical application on skin health, particularly regarding photoaging and wrinkle formation.

Beta-carotene is a potent antioxidant, and it is believed to help neutralize free radicals generated by UV exposure, thereby reducing oxidative stress—a key contributor to skin aging and wrinkle development. Some clinical studies have demonstrated that oral or topical beta-carotene, often in combination with other antioxidants, can improve skin elasticity, hydration, and overall appearance. For example, a randomized controlled trial published in Photodermatology, Photoimmunology & Photomedicine (2010) found that supplementation with carotenoids, including beta-carotene, provided some photoprotective effects and reduced the severity of photoaging. However, the magnitude of wrinkle reduction was modest, and results are often inconsistent across studies.

It is important to note that while vitamin A derivatives (like retinoids) have robust evidence for wrinkle reduction, beta-carotene itself is less potent and its effects are less pronounced. High doses of beta-carotene supplements are not recommended due to potential health risks, especially in smokers. In summary, there is some scientific basis for beta-carotene's use in wrinkle prevention or treatment, but the evidence is limited and less compelling than for other interventions.
