All UV irradiations were delivered through Westinghouse FS20 bulbs Westinghouse, Pittsburgh, PA that emit a spectrum with high irradiance in the UVB region and a peak at nm.
First, MED was determined in each recruited individual. To determine MED, for each volunteer five to eight skin sites 1×2 cm in a row were exposed to UV radiation at gradually increasing exposure times with an increment of 30 s.
The lowest UV dose that induced a just perceptible pinkness at the exposure site after 24 h was identified as the MED. In all experiments in this study solar UV-protected buttock skin sites were used because it is easier to obtain skin punch and keratome biopsies from the covered area of the body of human volunteers.
Our experience indicates that volunteers are not receptive to providing skin samples from other parts of the body. After determining the MED in individual volunteers, in a follow-up visit the buttock skin area was exposed to the predetermined 4× MED dose of UV irradiation.
This UV dose was selected based upon our previous observations and studies in human skin 28 , Skin punch biopsies 4 mm diameter, 0. Keratome biopsies 1. Skin biopsies were taken either from normal buttock skin non-UV exposed or at 6, 24 and 48 h after 4× MED UV irradiation with or without topical treatment with EGCG.
According to the protocol approved by the Institutional Review Board for Human Investigation, to avoid inconvenience to human subjects we should not take more than six skin punch biopsies or four keratome biopsies from a single human subject.
However, each data point is derived from at least three to four individuals treated at different time points. To maintain a similar treatment regimen, vehicle was also topically applied to control non-UV exposed and UV-alone exposed skin sites.
Immunostaining was performed on at least three to four different individuals of each group as described below. Immunohistochemical detection of H 2 O 2 in normal as well as UV-irradiated skin was performed following the procedure as described earlier Briefly, 6 μm thick frozen skin sections were incubated with 0.
The DAB—peroxidase reaction gave a brown reaction product and methyl green a blue nuclear counterstain. Thereafter, sections were incubated with anti-human CD11b anti-Mac-1 or its isotype control IgG 1. Bound anti-human CD11b was detected by incubation with biotinylated goat anti-mouse IgG 1 followed by peroxidase-labeled streptavidin.
Images from immunostained slides were obtained using a Zeiss Axiophot microscope Thornwood, NY and Kodak Ektachrome T film Rochester, NJ.
These were scanned using SprintScan software and formatted as tiff images in Adobe Photoshop and Microsoft Powerpoint in order to make composite figures. The epidermal and dermal skin layers were separated using the enzyme dispase as described earlier Thereafter, the epidermal layer was easily separated from the dermal layer using forceps.
Intracellular levels of H 2 O 2 were determined using dihydrorhodamine DHR as a specific fluorescent dye probe as described by Peus et al. Epidermal and dermal single cell suspensions from the skin keratome biopsies obtained from different treatment groups were prepared as described previously For estimation of intracellular H 2 O 2 , 1 epidermal or dermal cells from different treatment groups UV-exposed and non-UV-exposed were placed in each well of a well tissue culture plate in triplicate.
These cells were treated with DHR 5 μM for 45 min. Reduced DHR is irreversibly oxidized and converted to the red fluorescent compound rhodamine 32 by UVB-induced intracellular release of H 2 O 2.
Plates were read on a Cytofluor II fluorescence plate reader with an excitation wavelength of nm and an emission wavelength of nm. In aqueous solution nitric oxide NO rapidly degrades to nitrate and nitrite. In this procedure NO formation is determined spectrophotometrically by measuring its stable degradation product nitrite.
For accurate assessment of the total nitric oxide generated we considered it essential to monitor both nitrate and nitrite. In this procedure nitrate is enzymatically converted into nitrite by the enzyme nitrate reductase, followed by quantitation of nitrite using Griess reagent.
Thus nitric oxide was estimated in the cytosolic fraction of both epidermis and dermis in the form of total nitrite formed using a colorimetric nitric oxide assay kit Oxford Biomedical Research following the manufacturer's protocol.
The LPO assay was performed in epidermal microsomal fractions obtained from the different treatment groups. The generation of malondialdehyde MDA was employed as a marker of LPO and estimated by the method of Wright et al.
Briefly, epidermal microsomal protein 2. The reaction was terminated by addition of 0. The mixture was heated for 20 min at 90°C in a water bath.
After cooling, the MDA levels were measured in the clear supernatant by recording absorbance at nm. The final concentration of MDA generated during the reaction was calculated using a molar extinction coefficient of 1.
Skin keratome biopsies were obtained at the desired time points after UV exposure. GPx activity EC 1. The assay mixture consisted of 0. Catalase EC 1. Change in absorbance was recorded at nm at 15 s intervals for 2 min.
GSH level in epidermal cytosolic fractions was estimated by the traditional method of Sedlack and Lindsay The assay mixture consisted of 20—30 μg cytosolic fraction, 0.
After filtering the solution, 1. The color intensity was immediately read at nm in a spectrophotometer. All experiments were performed on at least three or four individuals with each assay conducted in duplicate or triplicate.
The results are expressed as means ± SD. We found that skin exposure to UV induces significant intracellular release of H 2 O 2 in the epidermis when measured at 6, 24 and 48 h post-irradiation Figure 1A. As shown in Figure 1B , a significant increase in release of H 2 O 2 was found at 48 h after UV exposure in dermis.
These data clearly indicate that pretreatment with EGCG of human skin inhibits UV-induced H 2 O 2 production. Because UV-induced H 2 O 2 -producing infiltrating cells reached up to the epidermis, the amount of H 2 O 2 is also increased therein 48 h post-UV irradiation. This confirms the notion that infiltrating cells are the major source of H 2 O 2 production.
This suggests that UV-induced infiltrating leukocytes may result in secondary injury to UV-exposed epidermis. This injury may result in further damage to keratinocytes and a breakdown in the structure of UV-exposed epidermis. Thus, inhibition of UV-induced production of H 2 O 2 by EGCG suggests an antioxidant potential of EGCG.
Further, it is important to mention that EGCG treatment most likely inhibits UV-induced oxidative stress in two ways, directly and indirectly. Direct effects include inhibition of UV-induced oxidative stress before induction of infiltration of leukocytes and is measured at 6 h after UV exposure.
The indirect effect is due to UV-induced infiltration of leukocytes, which are also the major source of ROS, and is measured at 24 and 48 h after UV exposure. Forty-eight hours after UV exposure of skin, infiltrating leukocytes were found in higher numbers, particularly in the dermis Figure 3B , compared with control, non-UV-exposed skin Figure 3A.
Although these cells are responsible for damage to and removal of infectious microorganisms through generation of ROS, excess production of ROS by these cells under the influence of UV exposure is considered to produce oxidative stress. Higher production of H 2 O 2 may generate higher levels of singlet oxygen and hydroxyl radicals and thus may produce oxidative stress.
Inhibition of UV-induced oxidative stress by EGCG treatment may therefore ameliorate UV-induced skin disorders. Although all three forms of nitric oxide synthase nNOS, iNOS and eNOS catalyze the production of NO by the same biochemical pathway, they vary in their tissue expression and activational requirements.
Activated macrophages are an important source of iNOS expression and the production of NO is central to the function of macrophages in infection and inflammation. We found that UV exposure of skin induces the production of NO, particularly in the cytosolic fraction of the epidermis Figure 4A.
The generation of NO at sites exposed to UV at 6, 24 and 48 h was ± 12, ± 14 and ± 21 μM, respectively, as compared with 16 ± 4 in the control non-UV-exposed sites Figure 4A. EGCG treatment was also found to inhibit UV-induced NO production in the dermis, as shown in Figure 4B.
ROS are highly reactive and can oxidize nucleic acids, proteins and lipid-rich cellular membranes and may lead to genetic alterations LPO is thus used as a marker of oxidative damage. In our present study we found that UV exposure of skin increases the level of epidermal LPO at all time points studied when measured in the form of MDA production Figure 5.
GPx is responsible for catalyzing the conversion of H 2 O 2 into water and oxygen. During this conversion GSH is converted to its oxidized form GSSG , with a concomitant decrease in GSH levels. GPx is also depleted. In this situation it is believed that GSH spontaneously oxidizes to GSSG utilizing H 2 O 2 molecules.
UV exposure of human skin was found to result in a lowering of GSH levels examined at 6—48 h after UV exposure Table I. Catalase, which is another antioxidant enzyme also responsible for catalyzing the conversion of UV-induced H 2 O 2 to water and oxygen, is slightly elevated at 24 and 48 h after a single UV exposure.
The elevated level of catalase after a single UV exposure also indicates conversion of the enhanced H 2 O 2 to water and oxygen. In the case of antioxidant enzymes, EGCG treatment before UV exposure was found to reverse the UV-induced activation or depletion of these enzymes.
These enzymic analyses were also performed in dermal cytosolic fractions of different treatment groups but did not provide a consistent pattern for any enzyme.
Our data demonstrate that a single exposure of human skin to UV 4× MED radiation is capable of generating ROS when measured using markers such as H 2 O 2 and NO production in both epidermis and dermis.
Changes in the levels of these parameters in the dermis also demonstrate the depth of penetration of UV radiation, as well as its damaging potential in deeper skin cells. At all time points studied UV exposure of the skin enhanced the levels of H 2 O 2 and NO production Figures 1 and 4.
Topical treatment with EGCG before UV exposure was found to inhibit UV-induced H 2 O 2 and NO production in both the epidermis and dermis, thus clearly demonstrating the protective potential of this antioxidant from green tea in human skin. EGCG treatment was also found to block UV-induced infiltration of leukocytes Figure 3 , which were shown to be the major source of ROS Figure 2.
UV-induced production of H 2 O 2 and NO is injurious and cytotoxic to target cells. Further, NO contains an unpaired electron and is paramagnetic, and thus may rapidly react with superoxide anions to form peroxynitrite anions in high yield. Peroxynitrite decomposition generates a strong oxidant with a reactivity similar to hydroxyl radicals.
Inhibition of both UV-induced H 2 O 2 and NO formation by EGCG is thus an additional antioxidant potential of this chemopreventive candidate.
Although under certain circumstances ROS help the host system to destroy invading microorganisms 37 , they also damage host tissues and create suitable conditions for various disease states 37 , The accumulation of UV-induced infiltrating cells is a characteristic feature of skin inflammation and further generation of ROS.
It is important to mention that EGCG shows a peak of absorption near nm in the UV range, which indicates that EGCG possibly does not absorb wavelengths within the UVB or UVA range. In our efforts to translate the chemopreventive effect of EGCG from murine skin to human skin we have found that treatment of human skin with EGCG before UV exposure significantly inhibited UV-induced epidermal LPO at every time point studied, i.
LPO in biological membranes is a free radical-mediated event and is regulated by the availability of substrates in the form of polyunsaturated fatty acids, prooxidants which promote peroxidation and antioxidant defences such as α-tocopherol, GSH, β-carotene and superoxide dismutase 38 — LPO is highly detrimental to cell membrane structure and function.
Elevated levels of LPO have been linked to injurious effects such as loss of fluidity, inactivation of membrane enzymes and receptors, increased permeability to ions and, eventually, rupture of the cell membrane leading to release of cell organelles 38 , 41 , Peroxidation products can also result in damage to crucial biomolecules, including DNA 43 , Thus inhibition of UV-induced elevated LPO levels by EGCG in human skin should reduce the risk factors related to the UV-induced, ROS-mediated tumor promoting effects of UV radiation in cutaneous inflammatory responses and malignancies.
In previous studies we have shown that topical application of EGCG to human skin before UV irradiation inhibits UV-induced epidermal prostaglandin synthesis through inhibition of cyclooxygenase activity It has been shown that enhanced cycloxygenase and lipoxygenase activity can trigger LPO in biological systems Indirectly, inhibition of UV induction of cyclooxygenase may reduce oxidative stress through inhibition of LPO.
The cellular concentration of ROS is determined by their rates of generation and detoxification. Antioxidant enzymes function cooperatively and any change in one of them may affect the equilibrium state, leading to excessive production of ROS, which may cause cellular damage and other biochemical alterations, such as inflammation, lipid peroxidation, DNA damage and enzyme activation or inactivation 45 , It is interesting to find that a single UV exposure of human skin to 4× MED enhances catalase activity, which demonstrates that skin cellular targets activated their defense system to protect the cells from UV-induced adverse effects.
In summary, we have demonstrated a potent inhibitory effect of EGCG against UV-induced ROS production and antioxidant enzyme expression in human skin. Other studies have verified that EGCG possesses several-fold higher antioxidant activity than vitamin C and α-tocopherol These effects of EGCG could be, at least in part, the mechanisms of action by which EGCG affords protection against UV-induced carcinogenesis.
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.

Cuppa anyone? The antioxidants build up under skin and protect it and they also protect the eyes! Green tea is truly amazing.
I read that drinking it without food is best for maximum absorption, but this is a habit I practice anyway as it can mildly interfere with some mineral absorption such as iron and I believe zinc when you're consuming these things with the tea. For me it is much more affordable to consume green tea than to buy extracts for topical use.
And the benefits are seemingly unlimited when ingested. And this is all just what science knows so far there's so much about antioxidants and the way foods work namely the amazing plant foods we should all be living off of in general, that's yet to be discovered by man and probably never quite will be.
