Micro needling is a very simple, effective and minimally invasive therapeutic technique. It was initially introduced for skin rejuvenation, however now it is being used for a wide range of indications including acne scar, post traumatic burn scars, androgenetic alopecia, skin tightening, pore reduction, hyperpigmentation, drug delivery, stretch marks and many more.
The micro needling technique is based on creating thousands of puncture channels into the skin , which are delivered by small, solid needles. These microscopic wounds produce a powerful stimulus that initiates regenerative wound healing.
The needle action is compared to an electric potential, increasing the fibroblast activity with formation of new collagen, improving blood supply along with growth factor stimulation.
Depending upon the desired action there are different types of stamps and rollers according to number, shape, and size of the needles. There are simple manual to electrical devices which can be chosen according to your dermatologists comfort and discretion.
With aging there is destruction of the elastic fibres and collagen fibres beginning from the superficial dermis involving with time the deep dermis. The consequence being a gradual decrease in the thickness and quality of the skin. With micro needling or the collagen induction therapy there is an overall increase in tissue firmness and skin thickness with histological studies showing massive growth rates of collagen and elastin in the skin.
A huge variety of mesococktails ranging from antioxidants like vitamin C, glutathione for skin lightening, to stem cells therapy like platelet rich plasma and nanofat for hair and skin rejuvenation can be used with micro needling to enhance the uptake into the desired target. Transdermal delivery of these medicines provide an attractive alternative route of drug administration when compared to oral intake or intra dermal needle injections, because of its ability to bypass the harsh gastrointestinal tract and deliver therapeutics non invasively.
For hair restoration, a combination of microneedling with peptides, vitamins, minoxidil, stem cells, platelet rich plasma and nanofat can be given along with medical management to maximise results.
In a safe working environment, the combination therapy of micro needling with the infusion of active substances significantly enhances positive patient results. Indications like hyperpigmentation, acne and alopecia may effortlessly be treated on all types of skin and ethnicities. Depending on the indication, several treatment sessions at intervals of a few weeks are required for best outcome.
