What should you know about er yag 2940?

The wavelength is strongly absorbed by water, a major component of skin. Depending on the settings, the clinician can remove very thin surface layers or create controlled heat with less removal. This can support treatment of uneven texture, some scars, pigmentation concerns and selected lesions, but suitability depends on skin type, the target problem and healing history. The device and settings are not interchangeable with every resurfacing laser.

During a consultation, discuss active infection, cold-sore history, medicines, tanning, pigment changes after injury and previous procedures. After treatment, the skin may be red, swollen, tender or flaky while it repairs. Follow the prescribed cleansing and moisturising plan, do not pick peeling skin, and protect the area from sunlight as directed. The [Erbium YAG Laser](/technology/erbium-yag-laser/) page offers more technical context.

Contact the treating clinic for increasing pain, spreading warmth, pus, fever, blistering, unexpected bleeding, worsening swelling or a delayed healing area. Prompt advice matters more when treatment is close to the eyes or on a large area. Do not restart exfoliating products or active creams until the clinician confirms that the skin barrier has recovered.

What problem is this laser expected to improve? Will treatment remove surface skin or mainly heat it? What preparation, downtime and pigment precautions apply to my skin, and what signs should prompt a review?
