Abstract Epigallocatechin gallate EGCG has the effect to protect skin from ultraviolet B UVB induced damages, but it is unstable under ambient conditions, being susceptible to become brown in color.

Introduction Skin is the body's first line of defense and it acts as a shield to protect the body from environmental stress. Materials and methods Reagents and equipment Medical vaseline was purchased from Zhengmao Petrochemical Co. Drug application and UVB irradiation GCG and EGCG were mixed with vaseline according to the above designed concentrations.

Transmission electron microscopy TEM The above fixed skin samples were washed in the phosphate buffer 0. Figure 1. Full size image. Results Effect of GCG on skin damage induced by UVB Testing results of skin quality indicators by skin analyzer show that compared to the blank control BC , UVB irradiation NC, negative control induced an increase in levels of skin oil, moisture and pigmentation, accompanying with a decrease in elasticity and collagen fibers in hairless mice skin.

Full size table. Figure 2. Figure 3. Table 2 Effect of various treatments on UVB-induced formation of melanosomes. Figure 4. Figure 5. Table 3 Mitochondria damage index of various treatments.

Discussion Skin photoaging is a complex process involving light stress like UVB. Conclusion GCG protected hairless mice from UVB-induced skin photodamages by improving skin elasticity and collagen fibers, and inhibiting aberrations in mitochondria and formation of melanosomes.

Moreover, based on the extensive laboratory evidence supporting the antioxidant and anticarcinogenic properties of green tea, many skin care products supplemented with polyphenols from green tea are sold to consumers reviewed in ref.

It is unlikely that these skin care products have been tested in controlled clinical trials and the concentration of GTP within these preparations is not uniform. Therefore, on the basis of available data concerning the antioxidant and anticarcinogenic potential of green tea, appropriate clinical trials should be designed to translate animal data to human subjects.

Time-dependent effect of UV exposure on GPx and catalase activities and GSH level in epidermis of human skin and effect of pretreatment with EGCG on UV-induced effects on these parameters a.

Inhibition of time-dependent UV-induced H 2 O 2 production by EGCG in the epidermis A and dermis B of human skin. Epidermal and dermal single cell suspensions were prepared from the different treatment groups. One million cells from each treatment group were loaded into each well of a well culture plate in triplicate.

Details of the method for determination of UV-induced intracellular production of H 2 O 2 using DHR as a fluorescent dye probe are described in Materials and methods. Data are presented as means ± SD of values from four different individuals where each sample was assayed in duplicate or triplicate.

Inhibition of UV-induced H 2 O 2 production by EGCG treatment in human skin cells. Immunohistochemical detection of H 2 O 2 -producing cells was performed using the DAB—peroxidase reaction as detailed in Materials and methods.

Normal skin non-UV exposed did not show H 2 O 2 -producing cells A. UV-exposed skin showed the presence of H 2 O 2 -producing cells at 24 B and 48 h C after UV exposure. EGCG treatment prior to UV exposure inhibits UV-induced production of H 2 O 2 D. Representative data are shown from similar experiments performed in three different individuals with identical results.

Representative data are shown from similar experiments performed in four different individuals with identical results.

Scale bar: 50 μm. Inhibition of time-dependent UV-induced nitric oxide production by EGCG in the epidermis A and dermis B of human skin. Nitric oxide production was measured in the form of its stable degradation product, nitrite, in the cytosolic fraction of epidermis and dermis separately.

Details of the method employed are provided in Materials and methods. Inhibition of time-dependent UV-induced epidermal LPO by EGCG in human skin. LPO was measured in the microsomal fraction of the epidermis.

Generation of MDA was used as a marker of LPO. Details of the methods are provided in Materials and methods. Data are presented as means ± SD of values from four different individuals where each sample was assayed in triplicate.
