The erbium-doped yttrium aluminium garnet or Er:YAG laser can target superficial fine lines, freckles, and other skin discoloration. Depending on the extent of the treatment, the laser resurfacing can range from superficial to somewhat deeper. It’s considered ablative, but it generally doesn’t cause the deeper wounding that results from a CO2 laser.
Before undergoing an Er:YAG treatment, specialized skincare may be recommended. Doctors typically use topical anesthesia for less sensitive areas or a nerve block in areas prone to pain (like around the mouth). You may feel the warmth of the laser, and you’ll sense skin turning powdery.
After treatment, you’ll be red and a little raw, but crusting is uncommon. Skin must be treated very gently in the week or two following the treatment, and it may have redness for up to two months.
