How Microneedling Smooths Your Wrinkles

Weigh the benefits, risks and costs


You’ve probably seen ads for microneedling in beauty or health magazines. They promise youthful and rejuvenated skin. But can hundreds of tiny needle pricks really make your skin look better?

The short answer is yes. It can offer benefits if you’re looking to refresh skin damaged from sun exposure, smooth out wrinkles or make scars from acne less noticeable.

Dermatologist Amy Kassouf, MD, answers six questions on what you should know about this popular cosmetic procedure.

Q: How does microneedling work?

A: Also known as collagen induction therapy, microneedling involves either a fine-needle roller or pen device that creates tiny holes in the top layer of the skin. An application of skin cream or serum is often added after the procedure.

This “controlled injury” process opens up your skin with tiny tears. Then, healing promotes collagen production, which helps fill in and smooth out wrinkles and fine lines, Dr. Kassouf says.

Q: What skin conditions does it treat?

A: In addition to treating wrinkled and sun-damaged skin, microneedling can improve scars from acne and other abnormalities. It is most commonly used on the face. But dermatologists also may use it on other parts of the body — to smooth out thighs or stomach stretch marks, for instance.

It can help smooth and rejuvenate your skin, but Dr. Kassouf always cautions her patients: If you have damaged skin, no procedure can make it look perfect again.

Q: What are the risks associated with microneedling?

A: Minor pain. A topical numbing agent helps control the “pokey” sensation you might feel during the procedure. But some patients may experience minor pain afterward and the skin may remain red for a few days.

Infection. Though the needle holes are tiny, they are open wounds and can become irritated or infected. You’ll need to keep the skin clean and avoid irritating lotions, swimming pools, gyms and other possible exposure to infection. “I’ve only seen one infection,” Dr. Kassouf says.

Skin discoloration. Some light or dark discoloration may occur, especially for people of color. But it is usually temporary, she says.

Q: Will insurance cover the cost?

A: Microneedling is an elective cosmetic procedure, so insurance will not cover any of the cost. Typically, a person needs four to six treatments for the best outcome, Dr. Kassouf says.

Your doctor will determine how many treatments you’ll need and estimate their cost.

Q: What about using a less expensive home kit?

A: “I have not personally worked with them,” Dr. Kassouf says. “They are less aggressive, but you might get some minor benefits.”

If you use a home kit, the key is to make sure the instruments you use are clean.

She says some patients who have used a kit tell her they were not satisfied with the results. She has had several who sought a professionally administered procedure after using a home kit.

Q: Do dermatologists have any reservations about microneedling?

A: While the treatment is often beneficial, dermatologists generally agree that more expensive laser resurfacing will produce better results. However, doctors consider microneedling as a more affordable alternative to fractional laser treatments, Dr. Kassouf says.

Fractional laser treatments use thermal energy to produce the tiny skin tears that stimulate collagen production. They improve fine lines and skin texture and color. They also may remove a layer of dead skin to expose fresher, healthier-looking skin.

They cost about four times as much as microneedling treatments. Most patients need three to five laser treatments for optimal results.

Dr. Kassouf offers a few final tips:

Before undergoing any skin procedure, talk to your dermatologist about what you hope the treatment will accomplish. Make sure you understand all the risks involved.

Remember that sun protection is essential before and after any procedure for optimal results.

Also, check your calendar before scheduling to make sure you have time to heal before any upcoming important engagement or event.
