Laser resurfacing uses a laser to improve the appearance of skin, or to treat minor facial flaws, by removing layers of skin.1 The American Society for Dermatologic Surgery (ASDS) names two common types: carbon dioxide (CO2) and erbium.1
Here is what each is used for, who the ASDS says is not a candidate, how healing goes and what can go wrong. It gives no settings and no results figures. Whether to have it is for you and a clinician.
The two common lasers
The ASDS says CO2 is used to treat wrinkles, scars, warts and other conditions. Erbium is used to remove superficial and moderately deep lines and wrinkles on the face, hands, neck and chest, and it causes fewer side effects than CO2.1 The ASDS lists these uses.1
What laser resurfacing can be used for, per the ASDS
- Acne scars
- Age spots
- Crow's feet
- Droopy eyelids
- Sagging skin
- Scars
- Sun-damaged skin
- Wrinkles
Who is not a candidate
The ASDS says patients with active acne or very dark skin usually are not good candidates.1 Ask your provider what they know about results in your skin type, and which laser they would choose.
Myth
Laser resurfacing is suitable for every skin type.
Fact
The ASDS says patients with active acne or very dark skin usually are not good candidates for laser resurfacing.
Before, during and healing
Before the procedure, a dermatologist reviews your medical history, examines you and discusses what you expect. If you have had herpes infections you are prescribed an antiviral before and after treatment, and an oral antibiotic may be prescribed. You may be asked to apply a topical retinoid for about four weeks before, and to avoid excessive sun.1
Medication is often given to help you relax and to reduce pain. Topical anesthetics numb small areas, and a nerve block or conscious sedation may be used for larger ones.1
Treated areas are usually dressed. Each day you soak the area, apply ointment and re-dress it. Healing takes three to 10 days, depending on the depth of the resurfacing and the type of laser.1

Who does it
Medical lasers are covered by the FDA's medical device regulations as well as the laser radiation rules.2 Which licensed people may operate one depends on your state. See our guide to who may inject. The ASDS, a society of dermatologic surgeons, says an ASDS member dermatologist reviews your history and expectations first.1
