Dermaroller

A treatment tool with micro-needles arranged on a cylinder. A dermaroller has a total of 192 micro-needles in 8 rows, each 0.1 mm in diameter and varying in length from 0.5 to 2.0 mm. This cylinder is moved vertically and horizontally across the skin to create micro-channels. Another tool used for micro-needling is the Dermastamp. In a Dermastamp, the needles are arranged on a round head instead of a cylinder. It has fewer and shorter needles compared to the dermaroller. Important criteria to consider in dermaroller treatment include needle symmetry, the material used, needle depth, needle count, and sterility.

What is Dermaroller Treatment?

With a dermaroller, an average of 6-10 star-shaped applications are performed on each area. Repeatedly passing over the same area creates 250-300 micro-channels. These micro-channels close naturally within approximately 20 minutes with the skin’s own elasticity, leaving no marks. Because the channels created by the dermaroller are perceived by the skin as wounds, the skin activates its own growth factors, triggering its wound repair mechanism. However, since there is no actual wound, the collagen, hyaluronic acid, elastin fibers, and new cell structures produced provide an anti-aging effect.

The micro-needles on the dermaroller are 0.5 to 2.0 mm long. During treatment, these needles create micro-channels on the skin without causing any peeling or tearing. The main effect of these micro-channels on the skin is to increase the absorption of substances that are difficult to absorb through the skin, thus enhancing the effectiveness of the treatment. The formation of micro-channels is perceived by the skin as if a wound has formed. When a wound occurs in our skin, tissue factors are released. Thanks to these tissue factors, the synthesis of collagen and elastin, which make up our connective tissue, increases.

Furthermore, microvascular synthesis occurs, similar to the wound healing process. This results in much tighter and firmer skin, and a significant improvement is observed, especially in acne scars. How long does the effect of Dermaroller last and how many sessions are needed? The channels created by the Dermaroller close quickly. Complete closure takes 12 to 18 hours. Depending on the skin type and the treatment, it is repeated every two or four weeks. In any case, at least 4 treatment sessions are required.

On the other hand, thanks to the micro-channels opened, topical growth factors and stem cell extracts are delivered under the skin more quickly. Dermaroller treatment can be safely applied in anti-aging, general skin rejuvenation, acne scar treatment, stretch marks, dark spots, cellulite, under-eye circles, and hair loss.
