The Erbium : YAG Laser
Erbium: YAG lasers are used for laser resurfacing of human skin. Example uses include treating acne scarring, deep rhytides, and melasma. In addition to being absorbed by water, the output of Erbium: YAG lasers is also absorbed by hydroxyapatite, which makes it a good laser for cutting bone as well as soft tissue.
What are the benefits of Erbium: YAG laser?
- High-precision, tissue-selective treatment
- Intuitive, easy-to-use parameter selection
- Minimal residual thermal injury to the underlying tissue leading to less chance of persistent post-treatment redness and changes in pigmentation
- Low cost of consumables
- Less invasive than dermabrasion and chemical peeling
- Short downtime
What is E rbium : YAG laser used for?
- Atrophic acne scars
- Herpes simplex scars, smallpox scars
- Sun-damaged skin
- Mild to moderate facial wrinkles
- Uneven pigment (brown age spots, freckles, melasma)
- Seborrheic keratosis and other benign skin growth
- Some superficial non-melanoma skin cancers
- Some vascular birthmarks (capillary vascular malformations)
- All patients should be carefully examined before treatment.
- The eyes must be examined for scleral show (whites of eyes visible below the iris), lid lag (slow movement of eyelids), and ectropion (drooping of the lower eyelid) in patients desiring periorbital laser treatment.
- The presence of cutaneous disorders including seborrheic keratoses, solar lentigines, actinic keratoses, and skin cancers should be noted.
- Skin cancers must be treated adequately by other methods before any resurfacing procedure is performed.
- Laser skin resurfacing can lead to the reactivation of latent herpes simplex virus infection or predispose the patient to a primary herpes infection before the skin surface has healed.
- Little data exists to support the use of prophylactic antibiotics because of the relatively low incidence of bacterial infections reported.
