Lasers are typically not used to treat which of the following conditions?

Lasers are generally not used to treat active infections because their application can exacerbate the situation rather than provide a therapeutic benefit. Using lasers on infected tissue can cause increased inflammation, promote the spread of bacteria, and potentially worsen the infection. On the other hand, lasers are widely utilized for cosmetic and dermatological procedures, such as reducing wrinkles, removing unwanted hair, and treating age spots. These conditions are primarily non-infectious and can benefit from the targeted energy delivered by lasers to either stimulate collagen production, destroy hair follicles, or break down pigmentation. Hence, when considering the safety and efficacy of laser treatments, active infections are a contraindication, making this the correct answer for the question posed.
