What is Micro-needling?
Micro-needling or Collagen induction therapy is an excellent treatment for acne scar repair, fine lines and wrinkle reduction. It is a treatment which resurfaces the skin without laser or surgery with a minimal downtime. Micro-needling means the use of needles or ‘micro-needles’ to achieve a therapeutic effect on skin. Micro-needling is relatively new minimally invasive procedure which involves superficial and controlled puncturing of the skin by miniature fine needles. Micro-needling, originally was known as collagen induction therapy but now it is a well-known treatment option in atrophic acne scars and skin rejuvenation, Hair loss (Alopecia) treatment, transdermal drug delivery and treatment of stretch marks.
What is mechanism of action of Microneedling?
Micro-punctures are created using micro-needles which produce a controlled skin injury without actually damaging the epidermis. The penetration of micro needles makes a micro injury with pinpoint bleeding in superficial layer of the skin. This results in induction of wound healing cascade by making new collagen and
neovascularization as a result of the release of growth factors following penetration of needle into stratum corneum which is outer layer of skin.
Therefore, this procedure stimulates the body's own physiologic wound healing and maintain natural functions in the skin, ultimately skin tightening and improvement of atrophic scars with an overall better aesthetic appearance. Your body treats a small wound the exact same way as a large wound, and sends fibroblasts to create more collagen in the affected area. We are basically tricking your skin into thinking it has been wounded, but as a result, we're thickening the skin and improving the texture with this procedure.
What does the procedure of Microneedling look like?
Microneedling is a simple office-based procedure lasting 10 to 20 minutes depending on the area and reason of treatment. The patients must be counseled prior to the procedure explaining the expected outcomes, delayed response, and need for multiple sessions. Microneedling is usually performed under topical numbing cream. The cream is applied for a 30- 45 minutes before the procedure is started.
After achieving adequate anesthesia, the area to be treated is washed with saline and then ethanol solution to obtain an aseptic field. name of the instrument is Dermaroller or Dermapen or Rejuvapen, which has many super-tiny needles in the very tip to penetrate the stratum cornea, or the superficial layer of skin .The length of the needles can be adjusted by your practitioner between 0.5 to 2.5 millimeters.
The treatment creates micro-punctures from the needles in your skin. Uniform formation of small pinpoint bleeding on the area, mark the treatment endpoint. The pinpoint bleeding may simply be washed off with saline solution. The procedure is well-tolerated by the patients and there are usually no post-treatment sequel except slight erythema and edema lasting for 2–3 days. Sun avoidance and regular sunscreen use is crucial in the post-treatment period. The small pinpoint injuries on the treated skin heal within 2–3 days with no post-treatment sequel.
Depending on your problem, your practitioner decides what kind of serum is appropriate for you to be applied during the procedure. Usually the Microneedling procedure is being completed by applying Hyaluronic acid mask which acts as a deep moisturizer for the skin. It soothes and helps with repair of skin right after the job.
