What is microneedling? Benefits and use

Microneedling is a method that some dermatologists use to treat different skin conditions. The technique involves using multiple tiny, sterile needles to puncture the skin and cause physical trauma.
This trauma prompts the derma, a deeper layer of skin, to rebuild.

Microneedling may help address many skin-related complaints, including:

• Wrinkles
• Scarring
• Acne
• Alopecia
• Skin pigmentation issues
• Stretch marks
• Rosacea
• Loose skin, such as after weight loss or liposuction

It may also help rejuvenate the skin.

In addition, professionals can use microneedling to deposit medication, such as topical tretinoin or vitamin C, deeper into the skin. This can boost the treatment of a variety of issues, including acne scarring.

How does microneedling work?

Microneedling increases the production of collagen and other healing factors by causing trauma to the skin.

Collagen is an essential protein that helps keep the skin looking youthful, with a firm, smooth, and stretchy texture.

Aging causes the decline of collagen in the skin, contributing to wrinkles and other signs of aging.

Skin can also lose collagen due to injuries, such as acne scarring, stretch marks, or other scars.

It is important to realize that microneedling is not a quick fix, as it involves the growth of new skin. It can take several months for a person to see the full results of the procedure.

What are the benefits?

A 2018 systematic review found that microneedling is a safe and effective way to rejuvenate skin and treat scars and wrinkles.

The researchers acknowledged, however, that determining whether microneedling is a viable treatment option in all cases will require further research.

A press release from the American Academy of Dermatology also states that people can expect a reduction in the “appearance of large pores, fine lines and wrinkles, scars, and stretch marks.”

What are the risks?

The medical community generally considers microneedling to be safe and effective, but there are still some risks.

The primary risk is skin irritation after the procedure. Other side effects could include:

• Swelling
• Discomfort at the site
• Redness
• Bruising
• Dryness
• Flaking of the skin

Bleeding is an uncommon reaction to microneedling, though it may be more likely to occur after a deeper treatment.

Bleeding may also be more of a risk for people who have bleeding disorders or who are taking blood-thinning medications. It is important to disclose this information to a doctor before receiving this treatment.

There is also a risk of more serious side effects, including:

• Infection
• Skin pigment changes
• Reaction to topical medications used during treatment
• Some devices involve additional risks.

Those that use energy or heat can increase the likelihood of burns.

Finally, some people are not candidates for microneedling treatment, including those with:

• An active skin infection
• Active acne
• Keloid scarring
• An unstable skin type

Seeing a dermatologist or medical skin care professional who is experienced in these types of procedures will help minimize the risks.
