The procedure, being simple, can be done at home. However, dermatologists advice against it, as there is risk of infection and scarring.
Devices used for Micro-needling
In the procedure, the skin is punctured using fine needles; those needles can either be on a roller, which has wheels of needles, or pens, having a cluster of needles at the tip. The models used by doctors may vary; it can be motorized, which allows control of the needle depth. There are other models, which uses micro-needles, as well as radio-frequency energy. The radio- frequency is used to produce heat, which according to some publications helps grow collagen. However, radio-frequency procedure
