Which of the following patient conditions is a contraindication for laser treatments?

Active skin infections or severe acne serves as a contraindication for laser treatments due to the potential for exacerbating the infection and the risk of complications. When laser energy is applied to the skin, it can introduce heat and create micro-injuries, which may worsen an ongoing infection or inflamed acne. Additionally, treating already compromised skin can lead to further irritation, scarring, or spread of the infection, compromising the healing process and safety of the treatment.

In contrast, conditions like dry skin, recent sun exposure, and stretched skin may lead to adjustments in treatment protocols or additional precautions but do not outright prevent the use of laser therapies. Each of them can be managed appropriately, allowing for the safe administration of laser treatments when necessary.
