What does "laser-induced acne" refer to?

"Laser-induced acne" specifically refers to the phenomenon where acneic lesions appear following laser treatment. This can happen due to a variety of reasons related to the skin's reaction to the laser technology, such as the stimulation of the sebaceous glands, the irritation of the skin, or the disruption of the skin's natural barrier.

In certain cases, the healing process post-treatment can lead to an inflammatory response that exacerbates existing acne or results in new breakouts. Understanding this concept is crucial as it highlights the importance of patient assessment and management following laser treatments, especially for those with acne-prone skin.

The other options focus on different factors that can influence acne but do not accurately define "laser-induced acne." Hormonal changes and external irritants may contribute to acne but are unrelated to the effects of laser treatments. Additionally, while laser therapy can reduce acne in some cases, this does not pertain to the concept of acne that arises as a consequence of the treatment itself.
