What type of laser is commonly used for skin rejuvenation?

The CO2 laser is commonly used for skin rejuvenation due to its ability to remove outer layers of damaged skin while promoting collagen production in deeper skin layers. This laser operates at a specific wavelength that effectively targets water molecules in the skin, resulting in precise ablation and vaporization of skin tissue. The controlled nature of the CO2 laser allows for significant improvements in skin texture, tone, and overall appearance, making it a favored choice for various cosmetic procedures.

Erbium lasers, while also useful in skin resurfacing, primarily target a shallower depth in the skin, which may not be as effective for more severe skin issues. Diode lasers are typically employed for hair removal and vascular treatments rather than skin rejuvenation, and the Nd:YAG laser is primarily used for deeper tissue treatments, such as tattoo removal and vascular lesions, rather than for surface-level skin rejuvenation.
