Microneedling (micro needling), also known as skin needling or transdermal therapy, collagen induction therapy (CIT), and percutaneous collagen induction (PCI), is a procedure for skin resurfacing that involves the use of fine needles to create micro dermal wounds. Tiny needles break collagen bundles in the superficial layer of the dermis that are responsible for scars with subsequent induction of more collagen immediately under the epidermis. It is currently used in the cosmetic art to treat several skin conditions, such as pigmentary disorders, wrinkles, post-acne atrophic scars, burn-related scars, and big pores. Microneedling is minimally invasive, penetrating the skin microscopically, stimulating the production of elastin and collagen, which results in the reduction in appearance of fine lines and wrinkles, skin laxity, and scarring.

This procedure is considered a safe skin resurfacing treatment due to minimal damage induced to the skin, resulting in much less epidermal injury than seen with laser ablation. There is also a lower risk of hyperpigmentation and scarring, making it a suitable therapy choice for people with thin, sensitive, or ethnic skin types.

Recent studies have demonstrated success using microneedling treatments to improve skin appearance and reduce wrinkles and aging, also around the neck region. The studies also confirmed that fractionated injury from skin needling has an immediate effect on improving multiple scars types as well as wrinkles and may be an effective treatment option in their management.

Treatment of acne scarring is always a challenge. Microneedling though can be a simple and inexpensive office treatment option for the management of post-acne atrophic scars. Multiple minimally invasive sessions of skin microneedling are an effective treatment for post-acne atrophic scars as it stimulates the repair processes with the advantage of being a relatively risk-free, in-office procedure with minimal patient recovery time.

How does Micro-Needling work?

Microneedling works by stimulating the skin’s natural healing, which increases the production of collagen and elastin in the skin. The normal healing response begins the moment of tissue injury by the perforations of the micro needles.

What conditions can be treated or improved with Medical Micro-Needling?

  • Mild to moderate acne scarring; any new or old scars;
  • Fine lines and wrinkles;
  • Loose skin;
  • Skin texture and pore size;
  • Stretch marks
