What is a common risk associated with laser treatments if the skin is overheated?

When the skin is overheated during laser treatments, one of the most notable risks is hypo/hyper-pigmentation. This occurs due to the laser's effect on the skin's melanin production. Overheating can disrupt the normal pigment distribution, leading to areas of either reduced pigmentation (hypopigmentation) or increased pigmentation (hyperpigmentation).

Individuals with darker skin tones are particularly susceptible to these pigmentary changes, as the laser may stimulate excess melanin production in some areas while causing damage in others. Therefore, understanding the thermal effects of laser treatments and implementing proper cooling techniques and settings is crucial to minimizing these risks and ensuring even skin tone post-treatment.
