CO2 laser treatment aims to improve the appearance of the skin by removing the top layer and stimulating the formation of new skin cells.

Dermatologists, plastic surgeons, and other healthcare professionals may use carbon dioxide (CO2) lasers in skin resurfacing therapies.

A person may seek CO2 laser treatment to treat skin conditions, such as acne scars, fine lines or wrinkles, and skin aging.

This article explores how CO2 lasers work, different types of CO2 lasers, and the potential benefits. It also discusses the potential side effects of this treatment, the length of recovery, and alternative options.

A CO2 laser is a tool that healthcare professionals may use for various skin conditions.

CO2 lasers are part of a laser resurfacing process. The laser emits energy at a wavelength of 10,600 nanometersTrusted Source. Water within the skin cells absorbs this type of wavelength, resulting in the ablation of the superficial layer of the skin.

This treatment causes skin collagen to contract and remodel. Collagen is a protein in the body that providesTrusted Source a tightly organized fiber network and contributes to the skin’s elasticity.

When the skin starts healing after laser treatment, new skin starts to form that may be smoother, tighter, and more elastic.

Laser treatment times depend on a person’s skin type, skin concern, and the manufacturer of the laser’s instructions.
