What is microneedling? 

Collagen Induction Therapy (CIT) is also known as microneedling. This treatment involves pricking the skin multiple times using a specialty device that induces the regeneration of the collagen lattice. 

There are several ways that microneedling is done. The two most popular methods are manual rolling and the second is automated needling. Both of these methods have the same objective but there are advantages and disadvantages to each method. 

Advantages of dermarollers

  • The device is single use and therefore reduces the risk of cross contamination. 
  • The treatment time is short for larger areas. 
  • the rollers typically do not need any lubrication. 

Advantages of automated needling

  • The needles can be adjusted for length. This allows to change the treatment parameters. 
  • less chance of blood splatter
  • more affordable

Cosmetic CIT and Medical CIT

CIT is generally divided into two categories, which are cosmetic and medical. The difference is based on the length of the needles and the depth reaching in the skin. 

Cosmetic rollers needles typically range between 0.2 mm and 0.3mm. They micro injure the epidermis and stimulate keratinocytes to release growth factors and promote upregulation of epidermal growth factors. These rollers can be used by aestheticians. 

Medical dermarollers needles range from 0.5 mm - 3.0 mm and trigger the wound healing process to stimulate keratinocytes and fibroblasts. These CIT devices are strictly used by healthcare professionals. 

Medical Microneedling Treatment Details

The CIT devices that are considered medical use surgical stainless steel needles to make channels into the epidermis and dermis to release growth factors. This promotes scar less healing and the deposition of normal woven collagen versus scar collagen.

How does CIT and microneedling help with skin laxity and wrinkles? 

Increase availability of cell nutrients and the triggering of the wound healing cascade brings platelets, fibroblasts, epithelial, and immune cells together to facilitate wound healing.
