Health Microneedling in Aesthetic Medicine

By Dr. Harsha Jayakody 

Microneedling is a minimally invasive safe aesthetic treatment method, which uses very short and thin needles to puncture the outermost layer of the skin, called the epidermis. This treatment method was introduced a few decades back in the early ‘90’s. Microneedling can be used on all types of skin and it gives clinical results almost immediately. It is commonly used for skin rejuvenation in anti-ageing treatments, acne and other scarring, pore treatments, melasma, pigmentations, hair loss, and many other cosmetic related skin conditions. Microneedles only make micro-puncturing on the thin epidermis without ever piercing the next layer of the skin - the dermis layer. 

This action of micro-puncturing stimulates the wound healing mechanisms in the body and at the same time initiating the natural growth of brandnew cells. Various growth factors and connective tissueactivating proteins are released to the affected area following the treatment. It also increases the number of fibroblast cells, effectively regenerating a new connective tissue layer. Ultimately, the microneedle treatment leads to healthy skin with an enhanced texture. Physicians advise 3-4 treatments to be done one month apart. 

Microneedling utilises specialised devices such as Derma rollers, Electric Derma Pens and also devices with specific techniques such as Derma-stamping and Dermafrac equipment. The ‘needles’ used with methods are only 0.2 mm to 3.0 mm long, as they are only intended to slightly puncture the thin outermost layer of the skin. Derma rollers use fine gauged needles attached to a cylindrical surface. They pierce the skin at an angle when the roller is pushed over the skin. The quality of the derma rollers depends on the materials used, needle length, needle diameter, and the number of needles attached to the roller. 

The diameter of stainless-steel needles used in derma rollers is less than 0.15 mm. Too much pressure, speed, and incorrect technique may cause tearing of the epidermis skin layer. Comparatively, electric derma pens are easier to handle and can be used around all facial contours. It has adjustable settings to control the speed and the depth of needle penetration. Derma pen causes negligible pain compared to derma roller because of the vertical angle of penetration. 

In Derma-stamping, microneedles are used with a serum, enzyme, or chemical solution especially to treat wrinkles, scars, and stretch marks. Derma Frac is a combination of Microneedling with microdermabrasion, serum infusion, and phototherapy. The treatment time with Derma Frac is a bit longer compared to other methods as it consists of a combination of different modalities. Microneedling is becoming a popular aesthetic treatment modality because of its safety, minimal invasiveness, and rapid effectiveness when performed by a qualified and experienced medical physician.
