A carotene, lycopene is a bright red phytochemical found in many plants, vegetables, and fruits including tomatoes, watermelons, guavas, papayas, and gac (a fruit native to southeast Asia). It is an extremely powerful antioxidant (100 times more efficient at quenching singlet-oxygen than Vitamin E) with known protective properties against solar ultraviolet radiation.
Lycopene-Rich Products And Dietary Photoprotection
Following ingestion of lycopene or tomato-derived products rich in lycopene, photoprotective effects have been demonstrated…Dietary carotenoids may contribute to life-long protection against harmful UV radiation.
Dietary Tomato Paste Protects Against Ultraviolet Light-Induced Erythema In Humans
The data demonstrate that it is feasible to achieve protection against UV light-induced erythema by ingestion of a commonly consumed dietary source of lycopene.
Beta-Carotene, Alpha-Carotene, and Gamma-Carotene
A reddish-orange pigment abundant in plants, fruits, and vegetables such as palm fruit, carrots, pumpkin, sweet potatoes, and spinach, beta-carotene has been shown to decrease ultraviolet sensitivity and can, as needed, be converted into the active form of Vitamin A (retinal) in the human body. Alpha-carotene and gamma-carotene, both isomers of beta-carotene, also exist naturally in many fruits and vegetables, often together with beta-carotene, and similarly show Vitamin A activity.
Antioxidine contains a natural-occurring ratio of mixed carotenes from palm fruit. Beta-Carotene, Alpha-Carotene, and Gamma-Carotene all demonstrate comparable protective properties and, additionally, are an ideal, non-toxic way of obtaining an optimal dietary amount of Vitamin A. In addition to playing a diverse variety of roles in humans, Vitamin A is crucial to the proper functioning of the retina of the eye.
Supplementation With Beta-Carotene Or A Similar Amount Of Mixed Carotenoids Protects Humans From UV-Induced Erythema
Long-term supplementation for 12 weeks with 24 mg/day of a carotenoid mix supplying similar amounts of beta-carotene, lutein and lycopene ameliorates UV-induced erythema in humans; the effect is comparable to daily treatment with 24 mg of beta-carotene alone.
Protection From Sunburn With B-Carotene—A Meta-Analysis
Dietary supplementation of humans with beta-carotene provides protection against sunburn in a time-dependent manner.
A carotenoid belonging to a class of phytochemicals called xanthophylls (meaning “yellow leaves”), lutein is an antioxidant and important component of the retina of the eye. Extremely important in eye and skin health, lutein may help protect against age-related macular degeneration. Lutein is found in egg yolks, some fruits and nuts, and many leafy green vegetables and plants; some common sources of lutein include goji berries, kiwifruit, peas, kale, spinach, broccoli, zucchini, corn, chard, collard greens, Brussels sprouts, and pistachios.
Dietary Lutein Reduces Ultraviolet Radiation-Induced Inflammation and Immunosuppression
Lutein modulates the skin’s response to ultraviolet radiation and may contribute to the defense against some of the deleterious effects of solar radiation.
Beneficial Long-Term Effects Of Combined Oral/Topical Antioxidant Treatment With The Carotenoids Lutein And Zeaxanthin On Human Skin: A Double-Blind, Placebo-Controlled Study
Combined oral and topical administration of lutein and zeaxanthin provides the highest degree of antioxidant protection. However, oral and topical administration of these antioxidants individually also provides significant activity in the skin. In addition, oral administration of lutein may provide better protection than that afforded by topical application of this antioxidant when measured by changes in lipid peroxidation and photoprotective activity in the skin following UV light irradiation.
Also a naturally-occurring xanthophyll, zeaxanthin is structurally very similar to lutein. Zeaxanthin is an important component of the macular area of the retina of the eye and, along with lutein, may help protect the skin and eyes from blue and ultraviolet light. Zeaxanthin is found in egg yolks and many of the same leafy green vegetables and plants as lutein; paprika and saffron also contain zeaxanthin.
Lutein And Zeaxanthin In Eye And Skin Health
In the eye, lutein and zeaxanthin have been shown to filter high-energy wavelengths of visible light and act as antioxidants to protect against the formation of reactive oxygen species and subsequent free radicals. Human studies have demonstrated that lutein and zeaxanthin are present in the skin, and animal studies have provided evidence of significant efficacy against light-induced skin damage, especially the ultraviolet wavelengths. This article reviews the scientific literature pertaining to the effects that lutein and zeaxanthin exhibit in the human eye and skin.
