Question
What causes blister-like bumps to appear on and above my 9-month-old's lips?
Answer
The answers to your questions really depend on the cause of these bumps. If they are truly blisters (bumps filled with clear fluid), and if they tend to occur in the same place each time, she may have cold sores, which are caused by a virus. This infection is quite common in older children and adults, and less common in
infants. It can be treated with topical or oral medications, if necessary. There are several other causes of skin bumps around the mouth, including simple irritation, bacterial infection, and something called perioral dermatitis. Regardless of cause, you can rest assured that none of these is a predictor of future acne for your daughter. However, if she continues to develop new bumps, have her evaluated by her pediatrician.
