RPL™ (Reactive
Pulsed Light)
Technology - How
does it work?
RPL™ (Reactive Pulsed Light)
is an advanced technology
which uses clinically proven
IPL (Intense Pulsed Light)
technology in conjunction with
a skin tone and skin contact
sensor. The light emitted from
the device penetrates the
skin and is then absorbed by
the melanin pigment in the
hair shaft. The heat produced
by this light goes into the
follicle and generates a local
thermal effect, also known as
selective photothermolysis.
The thermal effect disables
the hair follicle which causes
a reduction in hair growth
while leaving the surrounding
skin unaffected and cool.
Long-term hair reduction–
Hair growth cycle
Two factors play an
important role in optimal
long-term hair reduction:
• Hair growth cycle.
Hair
growth involves three
phases: Anagen, Catagen,
and Telogen. Anagen is the
growth phase, while Catagen
and Telogen are the resting
phases. Permanent hair
reduction can only occur
in the Anagen phase, the
phase of growth. Since hair
growth is not synchronized, it
is recommended to complete
the full treatment protocol
to ensure every hair will
be exposed to treatment
during its Anagen phase.
• Skin tones (according to the
Fitzpatrick scale).
Darker
skin contains more melanin,
which competes with the
targeted hair for energy
absorption. When more
energy is absorbed into
the skin, there is a greater
risk of adverse effects.
Phase 1 - Anagen
(growth phase)
Phase 2 - Catagen
(regression phase)
Phase 3 - Telogen
(shedding phase)
