Correlations Between Macular, Skin, and Serum Carotenoids
Investigative Opthalmology & Visual Science, 2017 Ocular and systemic measurement and imaging of the macular carotenoids lutein and zeaxanthin have been employed extensively as potential biomarkers of AMD risk. In this study, we systematically compare dual wavelength retinal autofluorescence imaging (AFI) of macular pigment with skin resonance Raman spectroscopy (RRS) and serum carotenoid levels in a ...

Photoprotection and Skin Coloring by Oral Carotenoids
Dermatologica, 2009A new combination of β-carotene (25 mg) and canthaxanthin (35 mg) was clinically investigated in 74 patients with various photodermatoses and Ill patients with pigmentation disorders. The photoprotective action of this combination was ascertained in clinical experiments.

Optical detection methods for carotenoids in human skin
Archives of Biochemistry and Biophysics, 2015Resonance Raman spectroscopy and reflection spectroscopy are non-invasive optical quantitative methods for the measurement of carotenoid antioxidant levels in human skin in vivo. Since all tissue carotenoids are derived from the diet, optical monitoring in skin may serve as an objective indicator for fruit and vegetable intake, and more broadly also as

Dietary carotenoid bioavailability is rather low in comparison to other macronutrients. However, they are absorbed and distributed to hepatic and some extrahepatic tissues, including skin. Co-consumption of dietary fat is essential for carotenoid bioavailability.

Bioavailability of natural carotenoids in human skin compared to blood
European Journal of Pharmaceutics and Biopharmaceutics, 2010Skin functions and structure are significantly influenced by nutrients. Antioxidants protect the supportive layer of the skin against any damaging irradiation effects and the action of free radicals. A lack of suitable methods means that the pharmacokinetic properties of systemically applied carotenoids transferred into the skin remain poorly ...

Skin Photoprotection by Carotenoids
2009In Western populations, a lifestyle favouring tanned skin leads to increased exposure to natural and artificial sources of UV-radiation (UVR). To keep the adverse effects of this exposure, such as sunburn, immunosuppression, photoaging and photocarcinogenesis, to a minimum, nutritional manipulation of the basic endogenous protective properties of skin ...

Skin carotenoid levels in adult patients with psoriasis
Journal of the European Academy of Dermatology and Venereology, 2010AbstractBackground Psoriasis is an inflammatory disease that not only affects the skin but can also have systemic implications such as obesity and nutritional deficiencies. Carotenoids are vitamin A provitamins with anti‐oxidant properties that are present in human tissues including skin.Objectives To determine whether psoriasis is associated with ...

Influence of dietary carotenoids on radical scavenging capacity of the skin and skin lipids
European Journal of Pharmaceutics and Biopharmaceutics, 2013Nutrition rich in carotenoids is well known to prevent cell damage, premature skin aging, and skin cancer. Cutaneous carotenoids can be enriched in the skin by nutrition and topically applied antioxidants have shown an increase in radical protection after VIS/NIR irradiation.

AbstractSkin carotenoid status (SCS) measured by resonance Raman spectroscopy (RRS) may serve as an emerging alternative measurement for dietary carotenoid, fruit and vegetable (FV) intake although its application had not been assessed in a middle-aged and older population in Asia.

The Relation Between Carotenoids Measured in the Skin and Eye
The Journal of NutritionCarotenoid amounts measured in the skin and retina are increasingly being used as biomarkers of general health, function, and disease. However, whether they are directly interchangeable is not clear. Several previous studies comparing the measures in adults and children have found inconsistent results.The objective of this observational study is to ...
