Dermaroller is a way to treat scars left by acne or injuiry. It can also be used for reduction of wrinkles and stretch marks. Dermaroller works by way of inducing collagen in depressed acne scars, thereby "filling them up".
How does dermaroller work?
Dermaroller needles are 0.5-1.5 mm in length. The needles pierce the surface of the skin and create really tiny holes without damaging the skin. This pricking of skin stimulates the formation of new collagen and elastin in the skin. Collagen is the structural protein in the body and inducing collagen at the site of a scar can sort of "fill it up" and smoothen its appearance.
Mild discomfort and pain during derma roller application is common. This can be minimized by application of topical anesthesia before the procedure.
Skin can appear red with milt swelling that, usually subsides in 12-24 hours. Rarely, hyperpigmentation can occur at the area of application that gradually fades away on its own.
The results are visible within 3-6weeks. It required multiple settings of 3-6 treatments at regular intervals. The number of treatments depends on the indication that is used for.
