What is a potential side effect of laser treatment?

Skin irritation is a recognized potential side effect of laser treatment. This can manifest as redness, swelling, or a mild burning sensation in the treated area, which is a response of the skin to the heat generated by the laser. It is a common reaction as the skin is exposed to intense light and heat during the procedure.

While skin irritation usually resolves on its own within a few hours to days following treatment, it is essential for practitioners to inform patients about this possibility so they can prepare accordingly. Managing aftercare properly can help alleviate discomfort and prevent complications.

The other options do hold some truth in certain contexts. For instance, excessive hair growth can happen in rare cases, particularly if the laser settings are not appropriately calibrated for the individual's skin type and hair color. Sunburn could also be a concern if patients do not take proper precautions regarding sun exposure before and after treatment. However, skin irritation is the most direct and common side effect commonly reported by patients post-treatment.
