Laser skin resurfacing uses a wavelength of light to produce changes at the surface of the skin. The specific wavelength of light will determine what part of the skin is affected. In addition to wavelength, lasers can be confusing because of the terms fractional, non-fractional, ablative and non-ablative.
Non-fractional lasers are like a brush that paints all the skin. All the skin in a target zone is covered. A fractional laser affects only a part of the skin. Think of fractional lasers as the impressionist artist Monet using his paintbrush to place dots on parts of the canvas. A non-fractional laser is like a roller paint brush, covering the entire area without gaps in between. Fractional lasers have an advantage of allowing faster healing.
Non-ablative lasers heat parts of the skin without vaporizing the skin. Think of a non-ablative laser like a warming pad. An ablative laser removes parts of the skin. Think of an ablative laser like a microscopic drill (fractional ablative laser) or sandpaper (non-fractional ablative laser).
To add to the mix, there is also a technology called intense pulsed light (IPL). This is not a laser because multiple wavelengths of light are used. IPL is used to add energy to the skin at various depths to enhance collagen remodeling and rejuvenation.
Finally, various aesthetic laser manufacturers use their own proprietary names that have little resemblance to the underlying physics. This causes confusion for both practitioners and patients alike.
