Perifollicular Edema

Laser hair removal causes perifollicular edema, an irritation that looks like tiny bumps around the treated area. There may even appear to be a collection of fluid. This is a mild side effect that is not only common, it’s an expected reaction. On average, bumps last several hours but can take up to a few days to heal. Rubbing the area with an ice cube or patting it with a cold washcloth will help soothe any irritation.

Knowing what side effects to expect and which ones you should find alarming is important. Some common yet temporary side effects of laser hair removal include:

  • Tingling or numbness
  • Itching
  • Redness and slight irritation
  • Swelling around the hair follicle

Most side effects can be treated with a cool compress and some moisturizer, but if you suffer any of the following, consider finding a new location to undergo laser hair removal treatments.

  • Bruising of the treated area
  • Temporary hyperpigmentation, or a change in the pigment color of the skin
  • Purpura, or a purple undertone of the skin
  • Scabs around the treated area
