Which of the following lasers is commonly used for skin resurfacing?

The Erbium laser is commonly used for skin resurfacing due to its specific wavelength and ability to precisely target the water in the skin's tissues. This characteristic allows it to remove the outer layers of the skin effectively, promoting collagen production and encouraging the regeneration of new skin cells. Consequently, this laser is often employed for various skin concerns such as wrinkles, fine lines, and texture irregularities.

In addition, the Erbium laser is favored for its minimal thermal damage to surrounding tissues, which helps to reduce recovery time and improve overall patient comfort during the healing process. This makes it a highly effective choice for those seeking skin rejuvenation and resurfacing treatments, allowing for significant improvements with a relatively lower risk of complications compared to other laser types.

While other lasers also have their applications in aesthetic treatments, such as the Ruby and Alexander lasers, they are not primarily known for skin resurfacing. The YAG laser, although versatile and used for various procedures, is generally more focused on deeper tissue treatments rather than surface-level correction, making the Erbium laser the most suitable option for this particular application.
