What type of laser is typically used for non-ablative skin rejuvenation?

1. CO2 laser

2. Fractional laser

3. Erbium laser

4. Diode laser

The correct answer is: Fractional laser

For non-ablative skin rejuvenation, the fractional laser is typically used because it selectively targets skin tissue without completely ablating the surface layer. This method stimulates collagen production and promotes skin tightening while minimizing downtime. Fractional lasers work by delivering energy in a grid-like pattern, affecting a fraction of the skin at a time, which allows the surrounding tissue to heal and supports quicker recovery compared to ablative lasers. In contrast, CO2 and Erbium lasers are considered ablative, as they remove layers of skin tissue and are used for more dramatic results but often require longer recovery periods. Diode lasers are primarily used for hair removal and can also work for skin issues but are not typically classified under non-ablative rejuvenation techniques. Therefore, fractional lasers are recognized for their effectiveness in offering rejuvenation with significantly less disruption to the skin’s surface, making them the preferred option for non-ablative procedures.
