With fast changing climate, pollutants, depletion of the ozone layer, more and more people are looking to save their skin from these impacts. These factors also impact cell growth leading to premature ageing. Some researchers have found green tea even better than chemical products that protect skin from ageing.
In our previous posts, we have already discussed micronutrients called polyphenols naturally occurring in green tea. According to researchers at National Centre for Biotechnology Information, Epigallocatechin gallate (EGCG) has anti-oxidant, photoprotective and anti-inflammatory properties. In 2000, scientists lead by C.A. Elmets published their research in Journal of the American Academy of Dermatology in which they found that green tea extracts on skin reduces impact of ultraviolet (UV) rays of the sun. The scientists found that reddening of the skin due to sunburn reduced by more than 80 per cent and destruction of DNA due to UV exposure reduced by 45 per cent. Since EGCG does not absorb UV rays, it forms a protective layer on the outer skin. For the same reason, green tea extracts are also used by cancer patients going through chemotherapy.
Similarly, EGCG found in green tea also slows down the ageing of the cells. With the discovery of telomeres or tail of chromosome in the 1970s, scientists found that the length of the ‘tail’ was crucial for the life of the cell. During the process of cell division, the size of the tail keeps getting shorter due to oxidation. EGCG is an antioxidant that prevents the loss of the tail and helps it grow longer, thereby increasing the life of the cell and slowing the ageing process. At TeaOrb, we have varieties of green teas from Assam, rich in EGCG, which may bring back that healthy glow in your skin and protect you from harmful radiation.
