After ablative laser resurfacing, the treated skin will likely be swollen and itchy. The skin may change color. Your healthcare team applies a thick ointment to the treated skin and may cover it with an airtight and watertight dressing. You may take a pain reliever and use ice packs. New skin usually covers the area in 7 to 10 days. Full recovery takes at least a month.

Once the treatment area begins to heal, you'll notice that your skin looks and feels better than it did before the treatment. The effect may last for years.

Laser resurfacing can cause side effects, though they're milder and less likely with nonablative approaches than with ablative methods.

How manytypes of laser

Both ablative and nonablative methods can be done with a fractional laser, which creates microscopic columns of treated tissue. Fractional lasers shorten recovery time and reduce the risk of side effects. You'll likely need more than one treatment session. Use of fractional devices has become the widely preferred method.

Ablative laser resurfacing typically takes between 30 minutes and two hours, depending on the technique used and the size of the area treated. When done without a fractional laser, this approach usually needs only one treatment. If you're undergoing nonablative laser treatment or fractional Er:YAG laser resurfacing, you'll likely need 2 to 4 treatments scheduled over weeks or months to get the results you're looking for.

With fractional nonablative and fractional ablative procedures, you'll need 2 to 4 treatments to get noticeable results. These sessions are usually scheduled over weeks or months.

Laser resurfacing is often done in a clinic. This is sometimes referred to as an outpatient procedure because it's not done in a hospital. Your care team numbs the skin with medicine. For treatment to the whole face, your care team might give you a medicine to help you feel calm or less anxious. This is called sedation.

Types of laserin Physics

During ablative laser resurfacing, an intense beam of light energy is directed at your skin. This laser beam destroys the outer layer of skin, also called the epidermis. At the same time, the laser heats the underlying skin, called the dermis. This stimulates collagen production over time, resulting in smoother skin.

The recovery time after nonablative laser resurfacing is very short. Your skin might be swollen or change color for a few hours. Use ice packs as needed. Typically, you can resume your usual activities and skin routine right away.

As you age, you'll continue to get lines from squinting and smiling. New sun damage also can reverse your results. After laser resurfacing, always use sun protection. Every day, use a moisturizer and a sunscreen with an SPF of at least 30. Tinted sunscreens with iron oxide and titanium dioxide are useful for people with brown or Black skin. These products help protect against melasma and postinflammatory hyperpigmentation.
