Cara looked worse-for-wear leaving the London Edition Hotel after a crazy weekend of partying, Pride, and guest appearances with gal pal Taylor Swift. Going au natural, the beautiful and stylish 22-year-old supermodel revealed the effects that hard partying, heavy makeup and a lack of sleep has had on her skin. Dressed sporty chic and rocking a sleek pony tail, Cara concealed her eyes behind a pair of shades. Her light complexion is marked with small blemishes that can be caused by a wild weekend out. Cara has also been spotted smoking cigarettes, drinking and eating some particularly greasy food recently as she celebrated London's Gay Pride festivities and jamming out at the Glastonbury Festival. Being one of the most sought-after models in the world right now, Cara deserves to take some time off and indulge. But smoking and excessive alcohol can play a part in premature aging, accelerated wrinkle development and the restriction your skin layers from receiving nutrients. These habits, coupled with an unhealthy diet, can reek havoc on your skin's appearance. Cara has been open about not sticking to a very solid exercise routine, or taking diet and nutrition very seriously. Her excessive consumption of fatty fast foods and love of pizza is very well known, and a bit of a struggle for her personal trainer to contend with. While the model is naturally slim, her habits can catch up to her in other ways, such as her complexion or her overall health. What do you think of Cara Delevingne's anti-fitness approach?
