Comparison Laser Hair Removal & Ultrasonic - 1
Ultrasonic hair removal is a fairly recent method to eliminate unwanted hair, It has the fundamentally different to Laser Hair Removal. Next, let us know what they are different.
How Does It Works
Ultrasonic Hair Removal : With a special applicator ultrasound energy is directly channelled over the hair shaft to the root, where it is converted into heat and damages the follicle. As a result, the temperature inhibits the hair's re-growth. The skin is unaffected since the energy is applied directly on the hair shaft. The hair will be treated by Ultrasonic one by one so it enables precise eyebrow contouring.
Laser Hair Removal : The laser 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.
Good Candidate
Ultrasonic Hair Removal : Since the Ultrasonic energy is accurately applied through the hair shaft, the surrounding skin is not affected. So the Ultrasonic is applicable to all hair colors (such as white, black, blond, red and grey) and all skin tones. And it can be used safely for almost all body areas or for shaping those delicate areas such as eyebrows or bikini line.
At the same time, due to the selectiveness of the energy transfer, safety is expected to be significantly better and pain significantly lower.
Laser Hair Removal : Caucasian and European (Fitzpatrick skin type I, II, III) are the Best candidates for laser hair removal treatment. African descent (Fitzpatrick skin type VI) with dark brown skin or poor candidates for laser hair removal. Up until now, blonds, redheads and people with grey or lighter hair tones couldn't avail of laser treatment simply because lasers cannot detect the pigment in lighter hair.
Most individuals experience a slight stinging sensation as the laser pulses are applied. Some parts of the body do tend to be more sensitive than others, and sometimes redness or swelling will occur for a few hours afterwards.
