Use high-power laser to shave hairs, reduce hair length to 1/8 inches. If the hair is too long, it may produce carbon dust, so the handpiece should be cleaned regularly.Put the handpiece above the skin, turn on the switch,move laser around until all hairs are carbonized. Carbon reagent can be used to improve heat switch reaction.Notice that the handpiece may cause danger even when it is away from skin.
2.Laser Radiation
After the hairs are shaved by razor, this step starts laser radiation. The skin should be fully cleaned, if there exists dirt, it can cause danger as well as reduce the efficacy. Put the handpiece above the skin, (the laser output should not touch the skin and hair, or it may damage the laser). Set laser pulse to 10 pulse/sec and turn on the laser move handpiece around, but do not repeat over ten times on one tissue(1/2 inch circle), 30 or more pulses on one tissue can cause serious burn hurt. Reactions can be seen from the beginning, it is various on different patients.
Pain management during Laser Tattoo Removal treatment
Laser tattoo removal can be uncomfortable but is very tolerable in most cases. The pain is often described to be similar to that of hot oil on the skin, or a 'slap' from an elastic band. Depending on the patient's pain threshold, and while some patients may forgo anesthesia altogether, most patients will require some form of local anesthesia. Pre-treatment might include the application of an anesthetic cream under occlusion for 45 to 90 minutes prior to the laser treatment session. In very rare cases, if complete anesthesia is necessary, it can be administered locally by injections of 1% to 2% lidocaine with epinephrine.
Anecdotal reports have noted that patients receiving anesthesia by local injection will require additional treatments as the injection causes mechanical edema, spreading out the tattoo ink, which in turn makes it more difficult for the laser light to act on specific ink particles. It has been reported that infiltration of local anesthesia will add an additional treatment or two.
