Hello, Following treatment of Exilis Elite, patients can experience mild erythema and swelling due to heat which has been applied during treatment. This should quickly subside and many patients enjoy having slight swelling for lax skin as it gives them an indication of their results. However if redness or heat persists please contact your practitioner and attend for a review. In a very few cases there is a condition called panniculitis which can be triggered when Exilis is used to treat superficial fat. Your practitioner would be able to advise you on this, whilst this can be uncomfortable it is easily treated once diagnosed, with topical NSAID. I hope this helps but please seek reassurance with your original practitioner who will be happy to see you. Cavendish Clinic
