How long do jellyfish marks last?

Jellyfish stings can leave marks that typically last from a few days to several weeks, depending on the severity of the sting and individual skin sensitivity. The initial redness and swelling may subside within a few days, but discoloration or irritation can persist longer. In some cases, more severe stings can lead to lasting scars. Proper care and treatment can help minimize the duration and intensity of the marks.
