Which of the following is a potential side effect of laser treatment?

Hyperpigmentation is a known potential side effect of laser treatment, particularly in individuals with darker skin types or those who have a history of pigmentation issues. Laser treatments work by targeting specific pigments in the skin or hair follicles, and in some cases, they can cause an increase in melanin production. This can lead to darkened patches or spots where the treatment was applied, especially if the skin is not properly prepped or if post-treatment care instructions are not followed.

Additionally, certain lasers and energy levels may increase the risk of this side effect, particularly if there is excessive sun exposure following the treatment, as UV rays can exacerbate pigmentation changes. Understanding this side effect is essential for practitioners to provide appropriate pre- and post-care guidance to minimize risks and ensure the best outcomes for their patients.

In contrast, increased skin elasticity, immediate skin lifting, and permanent hair removal are not typically categorized as side effects but rather as desired outcomes or benefits that can be achieved with certain laser treatments. While they may be positive results of a successful procedure, they do not reflect the potential adverse reactions that could arise during or after treatment.
