What is the Erbium:Yag laser?

SharpLight Erbium:Yag Fractional Laser 2940 and Spectrum Erbium:Yag Fully Ablative Laser 2940 produce energy in a 2,940 nm wavelength which then gently penetrates the skin and is readily absorbed by water, scattering the heat effects of the laser light. It stimulates skin cell turnover and promotes the formation of collagen and elastin fibers that will strengthen the skin. The laser can remove both superficial and medium depth lines, including some scarring. It intensively treats old epidermal pigment cells and promotes the skin’s natural process for creating new, healthier tissue to replace the damaged cells.

How does Erbium: Yag work?

The erbium:Yag laser targets water in the skin leading to controlled vaporization of superficial cells and thermal injury in the dermis that results in collagen remodeling and healing. The thermal injury in the dermis stimulates the production of collagen, which can significantly reduce visible wrinkling and scars. In addition, the water vaporization results in a skin-peeling effect in the epidermal layer, improving the appearance of photo-damaged skin.

What does Erbium: Yag 2940 treat?

Laser skin resurfacing is used to reduce skin imperfections. Superficial sun damage, fine lines/wrinkles, skin laxity, brown/age spots, blotchiness, scars and certain precancerous growths can be addressed with the erbium:Yag.
