There’s not much you can do about a tomato-toned face post-workout, but your skin is another matter. ‘One of the biggest causes of activity-induced skin irritation is when people don’t wash their faces post-gym,’ says cosmetic dermatologist Dr Mervyn Patterson. ‘We assume sweat is clean, but that’s not the case.’ Sweat carries with it the grime that’s built up in our pores and, when left on our skin for prolonged periods, it settles back in, creating a prime breeding ground for breakouts. So why are 51 per cent of women not cleansing their face after exercise? Put simply, we don’t know what to do. More than three quarters of us are unaware of which products to use before and after exercise. Developed for active women, Pretty Athletic skincare targets concerns such as clogged pores, irritation and inflammation. Refresh with a spritz of Pretty Athletic Workout Glow Hyaluronic Vitamin Tonic (£17.49 for 100ml) pre- or post-workout, and combine with Pretty Athletic Cool Down Purifying Gel Cleanser (£17.99 for 100ml) afterwards. It’s skincare that works as hard as you do.
