Birthmark removal treatments, whether laser or surgical, can have side effects. Here's what you should know:Common Side Effects:Redness and Swelling: These are typical immediately following the procedure and usually subside within a few days to a week.Pain or Discomfort: You might experience mild pain or discomfort at the treatment site, which can often be managed with over-the-counter pain relievers as recommended by your dermatologist.Itching: Itching is a common part of the healing process.Crusting or Scabbing: The treated area may form crusts or scabs as it heals. It is crucial not to pick at these to prevent scarring.Less Common Side Effects:Changes in Pigmentation:Hyperpigmentation: The treated area may become darker than the surrounding skin.Hypopigmentation: The treated area may become lighter than the surrounding skin.Scarring: There's a risk of scarring, especially with surgical removal. The extent of scarring can vary depending on the size and location of the birthmark, as well as individual healing factors.Infection: Any procedure that involves breaking the skin carries a risk of infection. Your dermatologist will provide instructions on how to care for the wound to minimize this risk.Textural Changes: The skin texture in the treated area may change slightly, becoming either smoother or rougher.Rare Side Effects:Allergic Reactions: Although rare, allergic reactions to topical creams or other materials used during the procedure are possible.Nerve Damage: In very rare cases, nerve damage can occur, particularly with surgical removal if nerves are in the area of the birthmark.It's important to note that most side effects are temporary and resolve on their own. However, if you experience any severe or persistent side effects, such as signs of infection (increased pain, swelling, redness, pus) or unusual changes in sensation, contact your dermatologist immediately.
