HAIR REMOVAL TREATMENTS WITH 1064 NM WAVELENGTH
• The purpose of the treatment is to selectively treat the hair follicle without causing thermal damage to the
surrounding tissue.
o The sapphire window provides epidermal cooling and protection.
• Permanent hair reduction is achieved by using heat to disable the hair follicle and prevent re-growth.
o The bulb and bulge of the hair follicle, which are responsible for hair re-growth, are targeted by the
excel V laser.
o Because the bulb and bulge of the hair follicle must be present, do not pluck or wax targeted hair in
between treatment sessions.
• The excel V laser targets the melanin in the hair bulb and bulge; therefore, hair must be brown or black.
o The excel V laser does not target and cannot be absorbed by white, gray, or red hair.
TREATMENT INTERVALS
• Only the hair follicle in the anagen growth phase can be effectively targeted and disabled.
• Each hair goes through the 3 growth phases independently of the neighboring hairs, so not all hairs will be in
the same phase at the same time. Therefore, multiple treatments are required to achieve sufficient reduction
in hair growth.
• Treatment Interval recommendations are a general guideline only and are a compilation of intervals used by
successful operators.
o Facial hair: 6-8 week intervals between treatments
o Body hair: 8-10 week intervals between treatments
o Back or Leg hair: 10-12 week intervals between treatments
• Hormones, diseases, medication, and other factors can affect the treatment outcome.
• Treatments that are spaced too closely together may appear to be more successful within the first few
treatments. However, more treatment sessions may be required for the desired final outcome, because a
smaller percentage of regrown hairs may be available as targets.
• Patients should be assessed before each treatment to determine treatment intervals and settings.
o Hair may grow back lighter and finer, and settings may need to be adjusted to target this new hair.
• If the patient returns for treatment and there is minimal hair, it may be in a transitional or resting phase.
o Wait until hair is actively growing to resume treatment cycle.
• Facial skin has significantly more hair follicles per cm² than the body, which is why you can see results within
the first three to four treatments with shorter interval times.
• When in doubt, it is better to space the treatments farther apart than closer together.
