Ultrasonic hair removal is a unique way to treat hair follicles that produces lasting results. The advantage of this procedure is that it can be used for hair removal among blonds, redheads and people with grey or lighter hair tones.
With a special device, ultrasound energy is directly channeled over the hair shaft to the root, where it is converted into heat and affects only the hair follicle. As a result, the temperature inhibits the hair's re-growth without damaging the skin which remains unaffected since the energy is applied directly on the hair shaft. This new-found ultrasonic hair removal procedure involves the use of ultrasonic energy, a hand piece and a needle. As intimidating as these tools appear, the patient undergoing the ultrasonic hair removal procedure experiences minimal pain and irritation.
This hair removal technique ultrasonic generating device creates waves of vibration which disturb the placement of the hair follicle, causing the follicle to become detached from the epidermis which is the skin's outer layer. The process is requires treatment of each hair follicle individually. Though ultrasonic hair removal procedure causes minimal pain, an anesthetics or a topical numbing ointment can be administered at the site of unwanted hair.
The ultrasonic hair removal treatment works by selectively targeting the melanin pigment inside the hair follicle. The laser emits a pulse, which travels through the skin and is absorbed by the pigment (melanin) in the hair; the light skin around it reflects the light. The laser then heats up the hair's shaft and root, destroying it without affecting the skin or follicle. Then the hair is prevented to regrow any further. This method may employ a wide beam, so that many hairs can be treated at once.
