The Clarity II Effect
Patients will notice thin & thick hair bursting during the session & a reduction in count after the 1st session.
Alexandrite & Nd:YAG laser wavelengths have high absorption on melanin, when laser is absorbed, the energy thermally damages bulge & bulb cells, these cells are responsible for hair growth and removing them prevents future hair regrowth.
The hair is rich in melanin & has a life cycle of 3 stages:
- Anagen: this growing stage is the ideal target of laser hair removal, the hair is fully attached to the bulge & bulb cells which can be thermally damaged by burning the hair.
- Catagen & Telogen: hair in this stage stops growing and is not attached to the bulge & bulb cells, hence burning hair by laser doesn't remove bulge & bulb cells. These cells can be removed once the hair cycle returns to anagen stage, which explains the need for multiple sessions.
Hair removal lasers target melanin which is present in both hair & skin, hence a protection of skin from the thermal effect is needed. Hair removal lasers use different cooling technologies to cancel the thermal effect of laser & protect skin.
Clarity's proprietary Intelligent Cooling Device (ICD) cools the skin precisely & consistently in a way that prevents under-cooling of skin that may cause burns, and over-cooling that may leak to hair itself & affect results.
Efficacy of hair removal necessitates using a pulse duration shorter than the Thermal Relaxation Time (TRT) of hair, when achieved, the hair gains temperature faster than losing it till it reaches the burning point.
The TRT of the hair depends on its size, smaller hairs have low TRT which needs low pulse duration to reach the burning point.
Clarity II avails 1 msec ,the lowest pulse duration in hair removal supported by the high protection by the patent ICD cooling, which makes it effective in thick thin & resistant hair.
Oxyhemoglobin absorbs a portion of Nd:YAG laser energy, when laser is used with high enough energy, the vessels supplying the lesion with blood can be targeted and destroyed. Over few treatments the vascular lesion disappears, and the skin appearance improves.
Clarity II provides 2 & 3 mm spot sizes that enable treating small vascular lesions & blue veins with high accuracy & efficacy.
