Microneedling, also called medical needling, collagen induction therapy (CIT) or percutaneous collagen induction (PCI), is a skin treatment used to treat:
- fine lines
- scars (including acne scarring)
- stretch marks
- large pores
- hair loss
Microneedling uses multiple fine, sterile needles to puncture the skin with microscopic channels.
This intentional, controlled injury initiates a skin healing response, resulting in the increased production of collagen and elastin. The end result is thicker, plumper, firmer, smoother skin. Additionally, skincare products are able to penetrate more deeply into the skin, making them more effective.
Microneedling can be done in one of two ways:
One option is using a dermaroller. A cylinder with many fine, sharp needles is rolled over the target area. The needles are of various lengths, depending on the qualification level of the practitioner, the area to be treated and type of skin issue.
Alternatively, your practitioner may use a microneedling pen. These are handheld pen-like devices (e.g. Dermapen®) which have around 12 fine needles on the tip. Once switched on, these needles move rapidly in and out of the skin, at a depth set by the practitioner.
You can use dermarollers at home, however, medically qualified practitioners can use dermarollers and/or microneedling pens, which penetrate deeper into the skin, giving much better results. Additionally, you are at increased risk of infection due to poor sterilisation and storage, and increased risk of track marks due to needles being blunt.
Common brands include:
Microneedling can also be combined with other treatments such as PRP (platelet-rich plasma) therapy and mesotherapy.
