Speaking on behalf of Witch Skincare, Professor Justine Hextall gives this advice: €A thorough cleanse starts from within €“ it's not just about tackling the skin, it's about tackling the diet too. Kick-start a skin detox with a week of eating well and keeping hydrated, focusing on fruit, vegetables, fatty acid-rich avocado, nuts, plenty of water and not too much alcohol.

Those with spots are often very keen on strong washes, which can strip the skin and damage its protective barrier. A skin detox does not need to be harsh. Facial steaming is a fantastic way of opening up pores. Alternatively, customers can get the same effect by going to a steam room. After opening the pores, follow with a gentle exfoliation and apply a moisturiser before bed.€
