What is a potential side effect of laser therapy?

Hyperpigmentation is a potential side effect of laser therapy due to the way lasers interact with the skin and stimulate the melanin-producing cells. When laser energy is applied to the skin, it can provoke an inflammatory response, which may lead to increased melanin production in some individuals, particularly those with darker skin types. This increased pigmentation often manifests as darker patches on the skin following treatment.

It is important to note that the risk of hyperpigmentation can be influenced by several factors, including the type of laser used, the settings of the treatment, the patient's skin type, and pre-existing conditions. Proper post-treatment care, including sun protection and following up with a dermatologist, can help manage or minimize this side effect.

Other options such as scarring, infection, and swelling can occur with laser therapy as well, but hyperpigmentation specifically pertains to the changes in skin color due to melanin activity following the treatment.
