What is a potential risk of laser treatment on an active acne lesion?

Using lasers on active acne lesions can pose a significant risk of worsening the inflammation associated with the existing acne. This is because laser treatments often generate heat and can exacerbate the inflammatory processes already present in an active lesion. Additionally, increasing inflammation can lead to complications such as scarring. When the skin undergoes laser treatment, it may not respond favorably if the acne is still active; the disruption caused by the laser can lead to a more severe inflammatory response, increasing the likelihood of post-inflammatory hyperpigmentation or even scarring.

While lasers do have beneficial applications for acne lesions, especially when they are dormant or in the scarring phase, applying them on active lesions carries a considerable risk of adverse reactions, which is why selecting the right timing and considering the lesion's condition is crucial in treatment planning.
