What is a common side effect of laser hair removal?

Hyperpigmentation is a common side effect of laser hair removal due to the way that lasers target melanin in the hair and skin. When the laser energy is absorbed, it can sometimes cause the surrounding skin to darken, especially in individuals with darker skin tones. This occurs because the laser can affect melanin production in the skin, leading to a temporary increase in pigmentation.

While other side effects may occur, such as a possibility of hair regrowth due to various factors including treatment efficiency or hair cycle timing, hyperpigmentation is particularly notable and can happen to a wide range of skin types following treatment. Understanding this side effect helps practitioners inform their patients about potential risks and the importance of post-treatment care, which can include sun protection to minimize the chance of pigmentation changes. This awareness is crucial for maintaining patient satisfaction and skin health after treatments.
