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 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 ...

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 ...

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.

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.

Skin Carotenoids: A Biomarker of Fruit and Vegetable Intake in Children
Journal of the Academy of Nutrition and Dietetics, 2014Studies of adult subjects have found a strong correlation between serum carotenoids and skin carotenoids measured by resonance Raman spectroscopy (RRS). No published studies have examined correlations between skin and serum carotenoids among children.We aimed to validate skin RRS methodology against serum carotenoid measurements by high-performance ...

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 ...

Validation model for Raman based skin carotenoid detection
Archives of Biochemistry and Biophysics, 2010Raman spectroscopy holds promise as a rapid objective non-invasive optical method for the detection of carotenoid compounds in human tissue in vivo. Carotenoids are of interest due to their functions as antioxidants and/or optical absorbers of phototoxic light at deep blue and near UV wavelengths.

Carotenoids in the skin of certain species of birds
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1979Abstract 1. 1. The author has investigated the carotenoids in the skin of certain species of domestic and wild birds. 2. 2. By means of columnar and thin-layer chromatography, the following carotenoids were found to be present. 3. 3. In domestic birds: β-carotene, ϵ-carotene, canthaxanthin, β-cryptoxanthin, lutein-epoxide, zeaxanthin ...
