The most common side effects are minor and last 1 to 3 days. These side effects include:
- Discomfort
- Swelling
- Redness
Other possible side effects are rare when laser hair removal is performed by registered medical doctors or under the medical doctor's direct supervision. Other possible side effects include:
- Blistering
- Herpes simplex (cold sores) outbreaks
- Infections
- Scarring
- Skin lightening or darkening
In time, skin color tends to return to normal. Some changes to skin color, however, are permanent. This is why seeing a medical doctor who is skilled in laser treatments and has in-depth knowledge of the skin is so important.
It is also important to follow your laser technician instructions. Following both the before-treatment instructions and after-treatment instructions will greatly reduce your risk of side effects.
