Perioral dermatitis

[Vania]

Perioral dermatitis is a red, bumpy rash around the mouth and on the chin that resembles acne, rosacea, or both.
Although the exact cause of perioral dermatitis is unknown, exposure to corticosteroids that are applied to the skin, use of water or toothpaste that has fluoride in it, or both have been proposed as possible causes.
The disorder mainly affects children and women of childbearing age. The rash typically starts in the folds of skin on the sides of the nose (nasolabial folds) and spreads around the mouth (the perioral area). The rash can also spread around the eyes and to the forehead.
