What is it? 
Toasted Skin Syndrome, medically known as Erythema Ab Igne, is a skin condition characterised by a mottled, reddish-brown discolouration resulting from prolonged exposure to low heat levels.
 
It’s often associated with electronic devices like laptops or heating pads.
 
It typically manifests as a net-like red/brown pattern resembling a mild burn on the affected area.
What causes it? 
It’s caused by the consistent application of low-grade heat to the skin, so is more prevalent in the colder months when the use of heaters, electric blankets, hot water bottles etc are more frequently used. It often affects the shins of elderly people from sitting in front of a fire for long periods too. 
 
How can you prevent it? 
Toasted Skin Syndrome can be prevented by maintaining a safe distance from heat-emitting devices, using laptop cooling pads, as well as taking regular breaks to allow the skin to cool. 
What causes toasted Skin Syndrome?
Can it cause long-term damage? 
While Toasted Skin Syndrome is generally considered a benign condition, repeated exposure may lead to more persistent discolouration. 
 
How do you treat it? 
If Toasted Skin Syndrome becomes sore or uncomfortable, it is essential to discontinue the source of heat exposure immediately. Additionally, applying cool compresses and over-the-counter topical creams containing soothing ingredients like aloe vera can help alleviate discomfort. If you don’t see an improvement then I would recommend booking in with a Consultant Dermatologist who can diagnose (to make sure it is indeed toasted skin syndrome) and help you devise an action plan.
