What Is Microneedling?

Microneedling is a minimally invasive procedure that uses fine sterile needles to create controlled micro-injuries in the skin or scalp. The treatment is sometimes referred to as collagen induction therapy because it stimulates the body’s natural wound-healing response, encouraging the production of structural proteins such as collagen and elastin.

The procedure can be performed using a variety of devices, including automated microneedling pens, dermal rollers and dermal stamps. Depending on the treatment area and concern being addressed, needle depths may vary significantly between professional and at-home protocols.

For the skin, microneedling is commonly used to improve the appearance of:

• Fine lines and wrinkles
• Uneven skin texture
• Enlarged pores
• Acne scars
• Surgical scars
• Stretch marks

For the scalp, microneedling is increasingly incorporated into hair restoration protocols where the goal is to support scalp health, improve the delivery of topical treatments and create an environment that is more favorable for healthy hair growth.

Published Perspective

The American Academy of Dermatology describes microneedling as a procedure that stimulates the skin’s natural healing process, helping to generate new collagen and elastin. This process may improve the appearance of scars, fine lines, enlarged pores and overall skin quality.

The American Society for Dermatologic Surgery similarly recognizes microneedling as a collagen-induction procedure that can be used across a variety of skin concerns with relatively little downtime compared with more aggressive resurfacing treatments.

Clinical Perspective

According to Dr Carlos Escobar, a physician who regularly incorporates microneedling into aesthetic protocols:

“Microneedling is a very popular clinic modality as it is a simple and effective procedure for improving skin texture and fine lines. With the addition of PTT-6, healing is optimized and there is enhanced production of collagen and elastin, leading to firmer, more supple skin.”

This reflects an increasingly common clinical approach in which microneedling is paired with regenerative skincare technologies designed to support the skin during the recovery process.
