Yes, stomach acid can indeed burn skin.
Cells in your stomach produce hydrochloric acid, which is a potent acid used to break down food. While your stomach is lined with a protective mucus layer that shields it from the acid's corrosive effects, your skin lacks this protection. Because of this, direct contact with stomach acid can cause chemical burns. The severity of the burn depends on the concentration of the acid and the duration of exposure.
In summary, while stomach acid is safely contained within your stomach thanks to a protective lining, it poses a burn risk if it comes into contact with your skin.
