Shihōin Cursed Seal: Release

After storing large amounts of chakra within the cursed seal, the user releases the seal, causing striped lines to appear on the user's face. The seal regenerates any wounds the user may have and also gives a boost to their medical ninjutsu for a short amount of time. After wearing off, however, the cursed seal itself vanishes from the user's forehead. Releasing the seal also has the downside of causing the user to age faster than natural; resulting in an early death.
