Frequently Asked Questions
What treatments does the CoolTouch VARIA™ laser provide?
The CoolTouch VARIA is used for the treatment of surface veins and for the treatment
of unwanted hair. In addition, the VARIA has
a new continuous mode that is used for
skin tightening. Plus, when skin cooling is desired, the VARIA uses a cryogen
spray to provide cooling and protection to the skin.
Who performs the treatment?
That depends on state regulations and standards of practice in your area. However,
with proper training, treatments can be performed by ancillary heath care staff
under physician supervision, where allowed.
Can the CoolTouch VARIA treat all hair colors?
The Nd:YAG wavelength penetrates deeply to the base of the hair follicle to produce
a thermal injury that reduces hair growth. Melanin absorption plays a key role in
targeting the hair follicle. Therefore, hair that is white (little or no melanin)
cannot be treated effectively. Gray, blonde and red hair will often times not respond
as well as darker, coarser hair to laser light treatment of any wavelength.
How many treatments does it take for hair removal?
Hair growth occurs in cycles. The anagen phase (most active growth) is when hair
is thought to be most susceptible to laser treatments. Because follicles in a given
area can be in different growth stages, multiple treatments are required to achieve
significant reduction in hair growth.
How long does it take to do a treatment?
Treatment sessions for veins are generally set for a fixed amount of time, usually
20-30 minute sessions. Hair removal treatment times depend on the treatment area
size and can range from 15-30 minutes for small areas and up to an hour or more
for large treatment areas such as a man’s back.
