What Is Microneedling? 2 Dermatologists Explain

What Is Microneedling?

In the most basic terms, microneedling procedures involve applying tiny needles to the skin. "The needles penetrate into the skin, creating a controlled wound and taking advantage of the skin's ability to heal itself afterward," Dr. Zeichner tells POPSUGAR. In other words, these small wounds — known as "microinjuries" — trigger the body to create new collagen. This is why microneedling is also called Collagen Induction Therapy.

How Does Microneedling Work?

When it comes to the application method (and who's behind the device), you've got options. Both Dr. Zeichner and Dr. Bhanusali note that aestheticians can perform microneedling treatments, but they're limited to the superficial improvements you might also achieve with at-home tools. Board-certified dermatologists, on the other hand, are able to perform treatments that penetrate deeper into the skin — and use it to maximum efficiency. "In our clinics, we [can] combine microneedling with a laser treatment as a combo, getting both deep and superficial improvement for patients," Dr. Bhanusali says.

The Benefits of Microneedling

Collagen is key when it comes to microneedling. The amount that's produced can minimize the appearance of fine lines, wrinkles, and acne scars, making it a popular choice for a variety of people. It can also address hyperpigmentation and improve the skin's overall tone and texture. But that's not all. Dr. Bhanusali looks to microneedling to treat scars on darker skin types, too. "Many lasers aren't appropriate due to risk of complication," he says.

How Much Does Microneedling Cost?

If you're planning on visiting a dermatologist for your microneedling treatment, it'll most likely be performed with a pen-like device that punctures the outer layer of the skin in a stamping motion. Some options even include adding energy-based radiofrequency to tighten the skin. The cost can vary based on a number of factors — location and intensity, for example — but typically runs between $500 and $1000 per treatment.

Microneedling Results

Results are typically seen within a few weeks (or four to six weeks for scar treatments), and even just one treatment can be effective. "Many experts agree that a single treatment will give about a 25 percent improvement of skin tone and texture," Dr. Zeichner says. For optimal results, rejuvenation purposes, or scars, more treatments can be necessary.
