Permanent Epilation: The PermaYag^TM laser emits a luminous beam at a unique wavelength (1064 nanometers) that is mainly absorbed by the high melanin (pigment) concentration in hair. Laser energy thus absorbed by hair, down to the deepest part of its bulb (up to 7 mm into the skin), allows temperatures to rise beyond 160 degrees centigrade enabling destruction to occur.

This destruction becomes PERMANENT when hair is treated during its active growth phase. During activity, the dermal papilla (principal source of hair production) is attached to the hair. Laser energy absorbed by the hair bulb is delivered to the papilla this cauterizing it. Hair follicles successfully treated can no longer regenerate.

These hairs are therefore gone forever.

BIOPSIES PERFORMED 3 MONTHS AFTER TREATMENTS SHOW THE DISAPPEARANCE OF HAIR FOLLICLES.
Superficial and deep dermal tissues are left intact.

The duration of the alternating rest periods (catagen and telogen stage) can last up to six months depending on the body site. Gradually, these follicles reactivate.

Regular monthly treatments are necessary in order to progressively target hair in the growth phase.

Permanency is ultimately achieved.

Other Lasers: The shorter wavelengths (600-810 nanometers) of a Ruby, Alexandrite, and Diode laser are strongly absorbed by pigment (melanin) in skin.

As the laser beam is filtered by skin, absorption occurs mainly at the epidermal level thus limiting penetration to a mere 2-3 mm in depth.

Inadequately damaged, deeper follicles temporarily slow down hair growth. Since only the top two-third (2/3) of the follicle is targeted, complete follicular regeneration is inevitable.

Further, significant risk of pigment change, blistering, burns, prolonged redness and excessive discomfort exceeds the too short-termed expected benefits.

Not all ND: YAG Lasers are created equal!!!
