Advantage one: more thorough hair removal Laser hair removal must meet two important conditions, first: the laser can be fully absorbed by the hair follicle tissue; second, the laser can effectively cross the skin to reach the location of the hair follicle. The wavelength of the semiconductor laser is 800nm, which is in the near infrared region of the spectrum, where melanin is well absorbed, and can penetrate deep into the dermis and subcutaneous fatty tissue, acting on different parts and depths of the hair follicles, effectively removing hair from any part of the body and at any depth. The laser pulse time required for the best hair removal effect is related to the thickness of the hair, the thicker the hair, the longer the laser action time required Semiconductor hair removal laser laser pulse time from 5 milliseconds to 100 milliseconds, to obtain the ideal hair removal effect while effectively protecting the epidermis from thermal damage. Advantage two: no pigmentation is most suitable for Asian skin When the laser crosses the epidermis and acts on the hair follicle, the melanin in the basal cell layer of the epidermis absorbs the laser energy and produces an inflammatory reaction, causing postoperative skin pigmentation, which will last for ten days and will seriously affect the cosmetic effect. Asians are colored people. The melanin content in the epidermis is larger. This inflammation is particularly noticeable with traditional laser hair removal, such as the ruby or emerald laser. The semiconductor laser penetrates deeper and the epidermis absorbs very little laser energy, so there is no pigmentation, and the long pulse width ensures that the epidermis is effectively cooled during treatment to maximize the temperature drop of the hair follicle. Advantage 3: Safe without damaging skin How to avoid epidermal thermal damage in laser hair removal is the key to the success of the treatment, using sapphire contact cooling device, before, during and after laser irradiation, effectively reduce the epidermal temperature, so that the treatment and epidermal cooling are synchronized, allowing the doctor to use the maximum laser energy, not only to remove hair with good long-term effect, but also to protect normal skin tissue. The contact cooling system allows the affected skin to receive the laser treatment under pressure to prevent the laser energy from damaging the capillary tissue. At the same time, research shows that this compression force can make the light energy irradiated to the base of the hair follicle increased by 30-40%. Advantage 4: Fast treatment speed The new semiconductor hair removal laser spot is designed as a large 9mm square spot. When performing large area skin hair removal. It is not only efficient and fast, but also can eliminate the overlapping dead zone formed by the traditional laser round spot. Advantage 5: Combined with pressure operation during treatment Effectively maintains skin whitening and brings hair follicles closer to the laser.
