Cultured UV-induced human keratinocytes were treated with EGCG, and the effects on inflammatory pathways and nuclear translocation of the transcription factor NF-κB were assessed.
EGCG inhibited UVB- and UVA-induced inflammatory pathways and apoptosis in cultured human keratinocytes Xia et al. Research is underway to produce biological and functional cosmetics using the natural anti-microbial properties of catechins. Human epithelial KB cells cell experiments show thatflavanols and proanthocyanidin from Limonium brasiliense L.
brasiliense interact with gingipains to inhibit the adhesion of Porphyromonas gingivalis P. gingivalis to epithelial host cells de Oliveira et al. In studies of the anti-microbial activity of fullerene and its hydroxylated derivatives, C60 OH 44 was as potent and broadly effective as catechin, which was used as a control for evaluation Aoshima et al.
Green tea extracts significantly reduced the levels of Streptococcus mutans S. mutans in saliva and dental plaques of children Goyal et al. Allergies are caused by an over active immune system reaction, producing itching and inflammation. Contact with certain allergens leads to a sensitive condition.
Studies have been conducted on the anti-allergenic activity of catechins. The anti-allergenic components of the oolong tea tree and the inhibitory activity of catechins on histamine released from rat peritoneal mast cells passively sensitised with the anti-egg albumin IgE antibody were investigated.
GCG was the most potent anti-allergenic component among tea catechins Ohmori et al. Extracts of Acerola bagasse A. bagasse can modulate the activity of proteases that act on coagulant, anti-coagulant, and thrombolytic activities as well as the destruction of phospholipids, thereby decreasing inflammation and platelet aggregation Marques et al.

Some matrix metallo protease inhibitors may be a preventative measure to prevent dentin erosion-abrasion Magalhães et al. Many studies have been conducted on the prevention and treatment of viral infections measles, AIDS, chicken pox, SARS, MERS, Ebola, etc.
An experimental study demonstrated the anti-influenza virus activity of green tea catechins Ide et al. In clinical trials, gargling with green tea three times a day did not alter the rate of contracting the influenza virus.
The researchers suggested that further study of catechin anti-viral activities are needed Ide et al. Studies have found anti-cancer substances in plants that inhibit cancer cell proliferation, including catechins. Polyphenol-rich extracts from Lawsonia inermis L.
inermis L. Henna inhibit oxidative radicals and cancer cell proliferation Kumar et al. Catechins have excellent anti-oxidant activity, but their high molecular weight and binding to the lipid bilayer of the skin are obstacles to passing the skin barrier.
There have been numerous attempts to overcome this problem. Microneedle-mediated intradermal delivery enables EGCG to penetrate to deeper skin layers. Skin microporation with maltose microneedles facilitates the penetration of EGCG across the stratum corneum into the deeper skin layers, including the viable epidermis and dermis Puri et al.
Based on the use of oil-water emulsions with different oil contents, a mixture of polyphenols containing catechins using Franz-type diffusion cells permeated the epidermis and dermis in pig skin in vitro Zillich et al. Hydrophilic additives reduce the activity of flavonoids by increasing their solubility.

EGCG, quercetin, EGCG, and Ginkgo biloba extracts show excellent skin penetration in fresh white skin obtained from abdominal surgery on static Franz-type diffusion cells dal Belo et al.
Monoglycerol Ester MGE -liquid crystal LC -forming lipid and glycerol monoolate GMO -LC formulations have improved skin penetration from various physico-chemical properties of the drug. MGE formulations have lower viscosity, faster drug release, and better skin permeability than GMO formulations.
The low viscosity of the MGE-LC-preparations might affect drug diffusion and permeability through the skin Kadhum et al. Liposomes can actively pass skin layers through artificial phosphor lipid membranes.
Phospholipids have an outstanding affinity for certain groups of flavonoids, and a mixture of catechins and phytosomes, a complex of naturally active components and phospholipids mainly lecithinenhances skin elasticity Bombardelli The interaction between fish collagen peptide FCP and EGCG was analysed using spectroscopic techniques, such as fluorescence spectres copy circular dichroism and Fourier-transform infrared spectroscopy FTIR.
More exposure of proline was found when FCP-EGCG complexes formed. FCP acts as an enhancer of EGCG and increases the absorption of EGCG into the skin and the body Yang et al.
Chitosan microparticles containing green tea extracts show permeation of catechins into subcutaneous tissues, and metabolism studies show that chitosan microparticles improve subcutaneous delivery of catechins while limiting their degradation by skin enzymes Wisuitiprot et al.
The effects of natural extracts, including catechins, on cell activity have been studied extensively. Extracts of black, green, and white tea have anti-melanogenic activities in immortalised melanocytes.
Fermented tea leaves have the lowest cytotoxicity and the highest anti-melanogenic activities Kim et al. EGCG reduced the secretion and production of melanin in human melanoma cells in a mechanistic study promoting skin hydration that measured anti-oxidant and pigmentation properties.
EGCG increases hyaluronic acid synthase gene expression and cell proliferation Kim et al.
: Mood enhancement catechins| Tea Ingredients | Catechin | Catechins have been used in the tissue biopsy culture model to achieve optimised effects like those in an in vivo application. The anti-oxidant properties of EpiDerm are like those of living organisms, and the stability and anti-inflammatory effects of catechins in HaCaT cells and RBL-2H3 cells were objectively proven. In safety tests for human applications, propionidinB-2 epicatechin was nontoxic and nonmutagenic. The anti-oxidant properties of catechins make them suitable for use in hair dyes and containers for medicines and cosmetics to reduce oxidation of the contents. All these studies and achievements suggest that the anti-oxidant activities of catechins will contribute significantly to the development of cosmetics and to human health.

Increased glucose and cytokines in serum abnormally phosphorylate the residue of insulin receptor substrate-1 IRS-1 that regulates insulin signaling Alipourfard et al. The molecular pathology of Alzheimer's disease. Tea catechins and polyphenols: Health effects, metabolism, and antioxidant functions. |
| Activity of catechins and their applications | A review found that while experimental research shows a modest beneficial effect, scientists could not conclude any consistent effects of green tea on overall cancer likelihood. Studies have found anti-cancer substances in plants that inhibit cancer cell proliferation, including catechins. From the mechanism, deficiency of eNOS cofactor tetrahydrobiopterin BH4 may be likely to be one of the main causes for the uncoupling of eNOS Förstermann and Münzel, ; Li and Förstermann, ; Forstermann et al. EGCG, quercetin, EGCG, and Ginkgo biloba extracts show excellent skin penetration in fresh white skin obtained from abdominal surgery on static Franz-type diffusion cells dal Belo et al. Therefore, improving abnormal lipid metabolism and alleviating oxidative stress is vital in the prevention and treatment of AS. |
