Our skin ages due to the constant exposure to sunlight as ultraviolet radiation from the sun penetrates cells and increases the number of damaging free radicals, especially the reactive oxygen species. Too many reactive oxygen species can be harmful because they can damage the DNA within our cells. Over time, this can lead to the accumulation of mutations which speed up ageing and destroy the skins supportive fibres, collagen and elastin, causing wrinkles. Recent studies strongly suggest the damage caused by reactive oxygen species may also initiate and exacerbate the development of skin cancers. A new Antioxidant, Tiron, offered 100% protection against UVA radiation and 100% protection against oxidative stress. As comparison NAC, a frequently used laboratory-based anti-oxidant, offered 20% protection against oxidative stress and 8% against UVA.
