What happens when you spray deodrant up close to your skin?

When you spray deodorant up close to your skin, the concentrated aerosol can cause irritation, redness, or a burning sensation due to the high concentration of chemicals and fragrances. Additionally, the propellants in the spray may lead to a cooling effect that can feel uncomfortable. It's generally recommended to hold the can at a distance to ensure even distribution and minimize skin irritation. Always check the product instructions for the best application practices.
