One of the latest trending pain-free anesthesia methods is the technique known as Comfort-in. This technique is a variation of the FUE hair transplantation method. This method is generally preferred by those with a needle phobia (trypanophobia). The practical mechanism of the Comfort-in method involves spraying anesthesia fluid under the skin by pressure on the target area of the needle, thus providing local anesthesia. This both frees the patient from needle pain and assures the medication is dispersed on an area larger than the needle profile.
