The "deodorant challenge" is a dangerous viral trend, mainly among young people, that involves spraying aerosol deodorant on bare skin for as long as possible, typically as a test of courage. The challenge can cause severe skin damage because the compressed propellant in the spray rapidly cools the skin, potentially lowering the temperature to as low as -30 °C within seconds. This extreme cold can cause frostbite-like "cold burns," damaging skin cells and proteins, leading to pain, blisters, peeling, and in severe cases, necrosis (skin tissue death) that may require skin grafts
. There is also a more hazardous version of the challenge that involves inhaling deodorant aerosols, which can be life-threatening. Inhaling the spray can cause oxygen deficiency, heart failure, respiratory paralysis, loss of consciousness, seizures, and even death due to toxic effects on the heart and brain
. Medical experts warn that the burns from this challenge can be first-, second-, or third-degree and may leave permanent scars. Immediate medical attention is advised if burns occur, including washing the area with warm water and consulting a doctor. Mild burns may only require moisturizing and protection, but severe burns might need surgical intervention
. Despite media coverage, the actual prevalence of the challenge is unclear and may be limited to small groups. However, health authorities strongly advise against participating due to the serious health risks involved
. In summary, the deodorant challenge is a risky social media dare that can cause severe skin burns and potentially fatal health consequences, especially when inhaling the spray. It should be avoided entirely
