Which of the following is a potential side effect of laser hair removal?

Hyperpigmentation can occur as a potential side effect of laser hair removal due to the way lasers target hair follicles. The laser emits energy that is absorbed by the pigment within the hair and skin. If the surrounding skin has more melanin or pigment and absorbs more energy than the hair follicles, it can lead to an increase in pigmentation in those areas. This is particularly more likely in individuals with darker skin tones, where there is more melanin present.

In addition, factors such as sun exposure before or after treatment can exacerbate this risk, emphasizing the importance of aftercare and protective measures post-treatment. By contrast, increased hair growth and hair loss in unwanted areas are not typical outcomes of the procedure; rather, they can be atypical or rare reactions to the treatment process. Lower self-esteem is more subjective and not a direct physiological side effect, making hyperpigmentation the more appropriate choice within the context of common side effects experienced following laser hair removal procedures.
