Describe the term "fractional laser."

• A. A laser that uses continuous light
• B. A laser delivering energy in a grid pattern
• C. A laser that only works on hair follicles
• D. A laser that does not penetrate the skin

Answer: (B)

The term "fractional laser" describes a technology that delivers laser energy in a grid pattern, targeting specific areas of the skin while leaving surrounding tissue unharmed. This selective approach promotes faster healing and reduces downtime, as only a fraction of the skin is treated at any given time. This technique is particularly beneficial for skin rejuvenation and treating issues such as scars, wrinkles, and pigmentation, as it stimulates the surrounding untreated areas to aid in healing and regenerate new skin. The grid pattern also aids in more uniform results, as it creates micro-injuries in the epidermis that trigger the body's natural healing response without affecting total skin layers. Other options are less accurate in defining fractional laser technology, as they either describe different types of lasers or fail to capture the essential mechanism of treating a fractional area of the skin.
