Laser
Resurfacing
Overview
Laser resurfacing is a
facial rejuvenation procedure that uses a laser to improve the skin's
appearance or treat minor facial flaws. It can be done with:
Ablative laser.
This type of laser removes the thin outer layer of skin (epidermis) and heats
the underlying skin (dermis), which stimulates the growth of collagen — a
protein that improves skin firmness and texture. As the epidermis heals and
regrows, the treated area appears smoother and tighter. Types of ablative
therapy include a carbon dioxide (CO2) laser, an erbium laser and combination
systems.
Nonablative laser or
light source. This approach also stimulates collagen
growth. It's a less aggressive approach than an ablative laser and has a
shorter recovery time. But the results are less noticeable. Types include
pulsed-dye laser, erbium (Er:YAG) and intense pulsed light (IPL) therapy.
Both methods can be
delivered with a fractional laser, which leaves microscopic columns of
untreated tissue throughout the treatment area. Fractional lasers were
developed to shorten recovery time and reduce the risk of side effects.
Laser resurfacing can lessen
the appearance of fine lines in the face. It can also treat loss of skin tone
and improve your complexion. Laser resurfacing can't eliminate excessive or
sagging skin.
Why it's done
Laser resurfacing can be
used to treat:
Fine wrinkles
Age spots
Uneven skin tone or texture
Sun-damaged skin
Mild to moderate acne
scars
Risks
Laser resurfacing can cause
side effects. Side effects are milder and less likely with nonablative
approaches than with ablative laser resurfacing.
Redness, swelling,
itching and pain. Treated skin may swell, itch or have a
burning sensation. Redness may be intense and might last for several months.
Acne.
Applying thick creams and bandages to your face after treatment can worsen acne
or cause you to temporarily develop tiny white bumps (milia) on treated skin.
Infection.
Laser resurfacing can lead to a bacterial, viral or fungal infection. The most
common infection is a flare-up of the herpes virus — the virus that causes cold
sores. In most cases, the herpes virus is already present but dormant in the
skin.
Changes in skin
color. Laser resurfacing can cause treated skin to
become darker than it was before treatment (hyperpigmentation) or lighter
(hypopigmentation). Permanent changes in skin color are more common in people
with dark brown or Black skin. Talk with your doctor about which laser
resurfacing technique reduces this risk.
Scarring.
Ablative laser resurfacing poses a slight risk of scarring.
Laser resurfacing isn't for
everyone. Your doctor might caution against laser resurfacing if you:
Have taken the acne
medication isotretinoin (Amnesteem) during the past year
Have a connective tissue or
autoimmune disease or a weak immune system
Have a history of keloid
scars
Have had radiation therapy
to the face
Have a
history of previous laser resurfacing
Are prone to cold sores or
have had a recent outbreak of cold sores or herpes virus
Have darker brown or Black
skin or are very tanned
Are pregnant or
breastfeeding
Have a history of an
outward-turning eyelid (ectropion)
How you prepare
Before you have laser
resurfacing, your doctor will likely:
Ask about your
medical history. Be prepared to answer questions about
current and past medical conditions and any medications you are taking or have
taken recently. Your doctor might also ask about previous cosmetic procedures
you've had and how you react to sun exposure — for example, do you burn easily?
rarely?
Do a physical exam.
Your doctor will inspect your skin and the area that will be treated. This
helps determine what changes can be made and how your physical features — for
example, the tone and thickness of your skin — might affect your results.
Discuss your
expectations. Talk with your doctor about your
motivations, expectations and the potential risks. Together, you can decide
whether laser resurfacing is right for you and, if so, which approach to use.
Make sure you understand how long it'll take to heal and what your results
might be.
Before laser resurfacing,
you might also need to:
Take medication to
prevent complications. If you're having ablative
laser resurfacing — or nonablative laser resurfacing and you have a history of
herpes infections around your mouth — your doctor will prescribe an antiviral
medication before and after treatment to prevent a viral infection. Depending
on your medical history, your doctor might recommend other medications before
your procedure.
Avoid unprotected sun
exposure. Too much sun up to two months before the
procedure can cause permanent irregular pigmentation in treated areas. Discuss
sun protection and acceptable sun exposure with your doctor.
Stop smoking. If
you smoke, try to stop at least two weeks before and after your treatment. This
improves your chance of avoiding complications and helps your body heal.
Arrange for a ride
home. If you're going to be sedated during laser can
expect resurfacing, you'll need help getting home after the procedure.
What you can expect.
During the procedure
How laser resurfacing
is done
Your doctor may do laser
resurfacing as an outpatient procedure. Your care team will numb skin with
medication. For extensive resurfacing, such as treatment to your whole face,
you might be sedated.
During ablative laser
resurfacing, an intense beam of light energy (laser) is directed at your skin.
The laser beam destroys the outer layer of skin (epidermis). At the same time,
the laser heats the underlying skin (dermis), which stimulates collagen
production over time, resulting in better skin tone and texture. Ablative laser
resurfacing typically takes between 30 minutes and two hours, depending on the
technique used and the size of the area treated. This approach usually needs
only one treatment.
If you're undergoing
nonablative laser treatment or fractional Er:YAG laser resurfacing, you'll
likely need 1 to 3 treatments scheduled over weeks or months to get the results
you're looking for.
After the procedure
After ablative laser
resurfacing, the treated skin will be raw, swollen and itchy. Your doctor will
apply a thick ointment to the treated skin and might cover the area with an
airtight and watertight dressing. You may take a pain reliever and use ice
packs. New skin usually covers the area in one or two weeks and full recovery
takes at least a month. During this time do not use products that may irritate
your face, such as cosmetics. And avoid situations that increase your risk of
infection, such as public whirlpools. Always use sun protection following laser
resurfacing.
After nonablative laser
resurfacing, recovery time is minimal. Your skin might be swollen or inflamed
for a few hours. Use ice packs as needed. Typically, you can resume your usual
activities and skin routine immediately.
Results
After ablative laser
resurfacing, your skin might stay inflamed for up to several months. But once
the treatment area begins to heal, you'll notice a difference in your skin
quality and appearance. The effects can last for years.
Results after nonablative
laser resurfacing tend to be gradual and progressive. You're more likely to
notice improvements in skin texture and pigment than in wrinkles.
After laser resurfacing,
always use sun protection. As you age, you'll continue to get lines by
squinting and smiling. New sun damage also can reverse your results. Every day,
use a moisturizer and a sunscreen with an SPF of at least 30.
