Mixed carotenoids, which include compounds such as beta-carotene, lutein, lycopene, and astaxanthin, have been studied for their skin health benefits, including the potential to reduce or prevent wrinkles. The scientific rationale is primarily based on their antioxidant properties. Carotenoids can neutralize free radicals generated by UV radiation and other environmental stressors, which are known contributors to skin aging and wrinkle formation. Clinical studies have shown that oral supplementation with certain carotenoids can increase skin carotenoid levels, improve skin photoprotection, and reduce the depth and appearance of wrinkles. For example, a 2012 randomized, double-blind study found that a daily mixture of carotenoids improved skin elasticity and reduced wrinkle depth after 12 weeks. Similarly, research on astaxanthin and lycopene has demonstrated improvements in skin texture and reduced signs of aging. However, the evidence is not uniformly strong for all carotenoids or all mixtures, and results can vary depending on the specific compounds and dosages used. Overall, while topical and oral carotenoid supplementation appears promising for supporting skin health and reducing wrinkles, more large-scale, well-controlled clinical trials are needed to confirm efficacy and determine optimal formulations. Thus, the use of mixed carotenoids for wrinkle reduction is supported by a moderate level of scientific evidence.
