A carbon dioxide laser (CO2 laser) resurfaces skin with targeted beams of light. As the first type of laser designed for skin resurfacing, itβs been a popular choice since the 1980s for the rejuvenation of aging and damaged skin.
So how does a CO2 laser work? Electricity runs through a gas-filled tube to produce a specific wavelength of light. The light is emitted in short, concentrated beams, which target water molecules and vaporize skin cells. The laser removes surface cells of the epidermis, making way for fresh, clear new skin.
At the same time, it penetrates the skin's deeper dermis layer to stimulate new collagen production, which firms and smooths skin over time.
CO2 laser treatments can address fine lines and wrinkles; discoloration (including sun damage and age spots); acne scars; stretch marks; and uneven skin texture on the face, neck, and chest.
CO2 lasers are one of the most effective treatments for wrinkles, sun damage, age spots, scars, and more. Learn about how they work, the risks, the costs, ...
