Dermabrasion is a skin-resurfacing procedure that uses a rapidly rotating device to remove the outer layer of skin.
Dermabrasion can decrease the appearance of fine facial lines and improve the look of many skin flaws, including acne scars, scars from surgery, age spots and wrinkles. Dermabrasion can be done alone or in combination with other cosmetic procedures
During dermabrasion, your doctor numbs your skin with anesthetics
Skin treated with dermabrasion will be sensitive and blotchy for several weeks. It might take about three months for your skin tone to return to normal
Dermabrasion can be used to treat or remove:
Scars caused by acne, surgery or injuries
Fine wrinkles, especially those around the mouth
Sun-damaged skin, including age spots
Redness and swelling. After dermabrasion, treated skin will be red and swollen. Swelling will begin to decrease within a few days to one week, but might last for weeks or even months.
Your new skin will be sensitive and blotchy for several weeks. It might take about three months for your skin tone to return to normal.
Acne. You might notice tiny white bumps (milia) on treated skin. These bumps usually disappear on their own or with the use of soap or an abrasive pad.
Enlarged pores. Dermabrasion might cause your pores to grow larger.
Changes in skin color. Dermabrasion often causes treated skin to temporarily become darker than normal (hyperpigmentation), lighter than normal (hypopigmentation) or blotchy. These problems are more common in people with skin of color and can sometimes be permanent.
Infection. Rarely, dermabrasion can lead to a bacterial, fungal or viral infection, such as a flare-up of the herpes virus, the virus that causes cold sores.
Scarring. Dermabrasion that's done too deeply can cause scarring. Steroid medications can be used to soften the appearance of these scars.
Other skin reactions. If you often develop allergic skin rashes or other skin reactions, dermabrasion might cause these reactions to flare up.
Dermabrasion isn't for everyone. Your doctor might caution against dermabrasion if you:
Have taken the oral acne medication isotretinoin (Myorisan, Claravis, others) during the past year
Have a personal or family history of ridged areas caused by an overgrowth of scar tissue (keloids)
Have acne or another pus-filled skin condition
Have frequent or severe outbreaks of cold sores
Have burn scars or skin that's been damaged by radiation treatments
Before dermabrasion, you might also need to:
Stop using certain medications. Before having dermabrasion, your doctor might recommend not taking aspirin, blood thinners and certain other medications.
Stop smoking. If you smoke, your doctor might ask you to stop smoking for a week or two before and after dermabrasion. Smoking decreases blood flow in the skin and can slow the healing process.
Take an antiviral medication. Your doctor will likely prescribe an antiviral medication before and after treatment to help prevent a viral infection.
Take an oral antibiotic. If you have acne, your doctor might recommend taking an oral antibiotic around the time of the procedure to help prevent a bacterial infection.
Have onabotulinumtoxinA (Botox) injections. These are usually given at least three days before the procedure and help most people achieve better results.
Use a retinoid cream. Your doctor might recommend using a retinoid cream such as tretinoin (Renova, Retin-A, others) for a few weeks before treatment to help with healing.
Avoid unprotected sun exposure. Too much sun exposure before the procedure can cause permanent irregular pigmentation in treated areas. Discuss sun protection and acceptable sun exposure with your doctor.
Arrange for a ride home. If you'll be sedated or receive a general anesthetic during the procedure, arrange for a ride home.
On the day of your procedure, wash your face. Do not apply any makeup or facial creams. Wear clothes that you don't have to pull over your head because you'll have a facial dressing after your procedure.
Your care team will give you anesthesia or sedation to decrease sensation. If you have questions about this, ask a member of your care team.
During the procedure, the doctor moves a small motorized device across the skin with constant, gentle pressure. The device has an abrasive wheel or brush for a tip that removes the outer skin layers.
Dermabrasion can take a few minutes to more than an hour, depending on how much skin is being treated. If you have deep scarring or you're having a large amount of skin treated, you might have dermabrasion done more than once or in stages.
After the procedure
After dermabrasion, treated skin will be covered with a moist, nonstick dressing. You will receive self-care instructions to follow at home and you might be given prescription pain medication.
You'll likely need to schedule a checkup soon after treatment so that your doctor can examine your skin and change your dressing.
At home, change your dressing as directed by your doctor. Your doctor will also let you know when you can begin regularly cleaning the treated area and applying protective ointments. Your self-care instructions will vary depending on the extent of your procedure.
While you're healing:
Treated skin will be red and swollen
You'll likely feel some burning, tingling or aching
A scab or crust will form over treated skin as it begins to heal
The growth of new skin might be itchy
To relieve pain after the procedure, take prescribed pain medication or an over-the-counter pain reliever, such as aspirin, ibuprofen
After dermabrasion, your new skin will be sensitive and red. Swelling will begin to decrease within a few days to a week, but can last for weeks or even months. It might take about three months for your skin tone to return to normal.
Once the treated area begins to heal, you'll notice that your skin looks smoother. Protect your skin from the sun for six to 12 months to prevent permanent skin color changes.
