Tata Harper Purifying Mask is a detoxifying kaolin clay mask that has been designed to combat the effects that exposure to environmental toxins have on the skin. Environmental toxins cause side effects such as tissue damage, oxidative stress and cell mutation. The damage caused by free radicals and chemical pollution causes degradation of collagen and elastin fibres, making it one of the biggest causes for premature skin ageing. This intensive skin treatment contains 23 high performance ingredients which work to restore balance and reverse the effects of environmental pollution on the skin.
