The effects of environmental pollution have been the subject of countless health and anti-ageing studies. Apart from causing damage to our respiratory health, urban pollution like UV rays and air pollution particles also accelerate the ageing process of our skin. When our skin is exposed to UV radiation and air pollution particles, free radicals are set off a chain reaction within skin cells as they are highly reactive. As a result, inflammation occurs which are in turn presented as dullness, hyperpigmentation, weakening of skin’s barrier function, a loss of elasticity and wrinkles. To neutralise these hazardous effects, your first line of defence is sun protection, which is why sunscreens are widely regarded by dermatologists as the most important anti-ageing investment.
However, according to research conducted by SkinCeuticals, sunscreens are only able to negate about 50 per cent of damage done by free radicals, leaving our skin to do the rest of the work. And while healthy skin is able to do so naturally, this ability also decreases with age. This, in turns means that your skin needs additional help in the form of antioxidants.
