In a nutshell, in winter, your skin is not at the top of your body's priority list. It is more prone to being damaged by pollution and external factors because the body will inherently source and spend its energy levels differently in order to keep warm. To detoxify the skin and help reduce the damaging factors caused by pollution, try a facial steam. Hold your face over a bowl of hot water for ten minutes with a towel wrapped around your head to help flush out toxins that have accumulated in your pores. Add a drop or two of a purifying essential oil, such as tea tree or rosemary, to help purify the skin. An added bonus: this will also help you to breathe more easily, perfect for easing the symptoms of a stuffy cold.
