What is Microneedling and what does it do?
Skin needling is a procedure that involves puncturing the skin multiple times with small needles attached to a cylindrical roller (Dermaroller) or mechanical dermal pen to induce collagen growth and improve atrophic (depressed) acne scarring.
Pioneered by Dr. Andre Camirand in the late 1990s as an evolutionary step from scar Subcision®, it simply involves the use of fine surgical steel needles attached to the roller mechanism. It’s applied directly to the skin in a crisscross motion.
The objective is to stimulate or puncture the skin to stimulate collagen and elastin production, smooth skin and promote scar or stretch mark reduction through the skins natural wound healing process.
For the medical grade level application of skin needling, the target of the needles and penetration is the upper dermis called the intermediate reticular dermis.
The effects of skin needling differ according to needle gauge, length and the manual pressure that’s used with the roller. Therefore the level of skin invasion and subsequent inflammation on the skin can vary from gentle stimulation to piercing the skin and drawing fluids, i.e., blood and lymph.
In order to achieve the best possible results, 2 to 3 treatments should be considered. As neo-collagenesis and neo-angiogenesis needs time to mature, the treatment intervals should be at least 4 – 6 weeks apart.
- Active acne.
- Infected skin.
- Tendency to keloids.
According to our experience in micro-needling with the Dermaroller, negative side effects have not been reported.
CASE 1: The scar on the pictures below was treated for 1 minute. The patient refused an anaesthetisation. Each part of the scar, as well as the scar edges, were punctured about 15 to 20 times until petechial showed up on the scar edges. After the procedure the treated area was cleaned with sterile saline solution. Further wound dressing was not necessary. One month later the patient returned for follow-up pictures. An improvement of 70% was noticeable. (A second treatment may result in an additional 10% to 15% improvement).
The pictures clearly indicate that the former depressive scar was filled with new collagen formation and the micro-needling induced new capillaries that migrated into the previous scar. The increased blood supply harmonised the old scar tissue with the surrounding pigmentation. (Pictures by Ivan Safonov and Horst Liebl)
