What is sensiLight™
The sensiLight™ device is an over-the-
counter device intended for the removal of
unwanted hair. sensiLight™ is also intended
for permanent reduction in hair regrowth,
defined as a long-term, stable reduction
in the number of hairs regrowing when
measured at 6, 9, and 12 months after the
completion of treatment regimen.
RPL™ (Reactive Pulsed Light)
how does it work?
sensiLight™ is based on the scientific
principle of selective photothermolysis.
sensiLight™ RPL™ (Reactive Pulsed Light)
advanced technology uses IPL technology
along with a combination of unique skin
condition sensors. The light penetrates the
epidermis to the dermis and is absorbed
by the melanin in the hair shaft. The heat
is generated by the absorbed light then
dissipates into the follicle and generates
local thermal damage, causing a reduction
in hair growth.
Long-term hair reduction – hair
growth cycle
Two factors play an important role in
optimal long-term hair reduction:
• Hair growth cycle 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 during the
Anagen phase.
• Skin types (according to the Fitzpatrick
scale) are illustrated on the diagram
at the back cover: darker skin contains
more melanin, which competes with the
targeted hair for energy light absorption.
When more light energy is absorbed
into the skin, there is a greater risk of
adverse effects, and the epidermis may be
damaged.

Who should use and how to
decide to use sensiLight™
• sensiLight™ is intended for women and men
who desire to remove unwanted hair.
• sensiLight™ is intended for use on the
legs, underarms, bikini line, back and arms.
• sensiLight™ is intended for use on skin
tone type 1 to 4 according to Fitzpatrick
skin chart below (see also colored
Fitzpatrick chart at the back cover).
12345 6
The use of sensiLight™ on naturally dark
skin is forbidden.
• sensiLight™ works best on dark hair or hair
that contains more melanin. Brown and
light brown hair will respond, but typically
will require more treatment sessions. Red
hair may show some response. White,
grey or blond hair shows a more limited
response. Nevertheless, some users
have noted hair reduction after multiple
treatment sessions.

Possible side effects
When using sensiLight™ according to
the instructions for use, side effects are
rare. However, every aesthetic procedure
including the usage of home use devices
may cause some degree of side effects.
Therefore, it is important that you
understand and accept the risks and
complications that can occur with pulsed
light hair removal system:

10
• Skin irritation - The use of pulsed light
hair removal system is generally very
well-tolerated, the majority of users do
feel a sensation of warmth and a mild
stinging sensation during treatment or a
few minutes after. Anything beyond this
skin irritation discomfort is abnormal and
means that either the energy level is too
high, or you shouldn’t continue using
sensiLight™ as you are unable to tolerate
the hair reduction application.
• Skin redness - Redness on the treated area
may appear right after using the application
or within 24 hours of using sensiLight™.
Consult your physician in case the redness
does not disappear within 2 to 3 days.
• Skin sensitivity - You may feel that your
skin in the treated area is more sensitive
so you may encounter dryness or flaking
of the skin.
• Skin burns - Rarely, burns on the treated
area can occur following the use of the
hair removal system. The burns can require
a few weeks to heal and, extremely rarely,
may leave a visible permanent scar.
• Scarring - In rare cases, permanent
scarring may occur. Usually when scarring
occurs it is in the form of a flat and white
lesion on the skin (hypotrophic). However,
it can be large and red (hypertrophic) or
large and extend beyond the margins
of the injury itself (keloid). Subsequent
aesthetic treatments may be required to
improve the appearance of the scar.
• Pigment changes - Use of sensiLight™
may cause temporary skin
hyperpigmentation (increased pigment or
brown discoloration) or hypopigmentation
(whitening) to the surrounding skin.
The risk is higher for people with darker
skin tones. Usually discoloration or
changes to skin pigment are temporary
and permanent hyperpigmentation or
hypopigmentation rarely occur.
• Excessive redness and swelling - Very
rarely, the treated area skin may become
very red and swollen. This side effect is
very common in sensitive areas of the
body. The redness and swelling should be
decreased after 2 to 7 days and you should
treat the area by applying ice. You should
avoid exposure to sun.

11
• Infection- In rare cases, infection of the
skin is a possible risk following a skin
burns caused by the application.
• Bruising - Blue-purple bruising is
exceedingly rare by using sensiLight™ and
can last 5 to 10 days. As the bruising fades,
there may be a rust-brown discoloration of
the skin (hyperpigmentation) that can be
permanent.
Benefits
sensiLight™ features an automatic built-in
skin color sensor that is designed to provide
you with complete safety and reassurance.
The sensor continually evaluates your skin
tone and allows sensiLight™ to perform only
on suitable areas. This smart safety feature
also automatically disables treatment if your
skin is too dark or too tanned.
As an extra precaution, sensiLight™ has
been designed to only emit a light pulse
when it is in a full contact with your skin.
Response to sensiLight™ hair reduction
differs between individuals depending on
biological factors and how closely treatment
instructions are followed.
Based on the treatment regime followed
in the User Guide you should expect to see
some improvement in 3-4 weeks.
The hair will continue to grow up to two
weeks after a hair reduction session.
However, thereafter as the hair grows in
three different stages the hairs will naturally
and gradually fall out depending on the hair
growth stage in during which the treatment
was done (only hairs in the active growth
phase will be affected). Some hair may not
be affected by sensiLight™ because of the
different hair growth phases.
For permanent reduction in hair regrowth,
defined as a long-term, stable reduction
in the number of hairs regrowing when
measured at 6, 9, and 12 months, you should
follow treatment regimen.

12
User instructions
sensiLight™ is intended for use on the legs,
underarms, bikini line, back and arms.
Device set-up
1. Remove all components from the box
(handheld device and power supply).
2. Before beginning the treatment, make
sure the device is clean, dry and intact.
3. Plug the power supply end into an
electrical outlet and the cord end into the
device socket (see image - item 6).
sensiLight™ is now ready to be used.
How to prepare yourself
1. Prior to use, make sure your skin is
shaved, clean and dry (free of any residue
such as powders, creams, makeup,
antiperspirants or deodorants).
2. Between treatments, you can shave but
don’t wax or pluck hair.
3. Never use flammable liquids such as
alcohol (including perfumes, sanitizers, or
other applications containing alcohol) or
acetone to clean the skin one hour before
using sensiLight™ as it may cause burning
of the skin.
Remember! sensiLight™ comes with a built-
in skin-tone sensor, enabling the application
only on a suitable skin range. This unique
safety feature will not let you treat areas
where your skin is too dark or too tanned,
even if your general skin type is lighter.
4. For sensiLight™ maintenance and prolong
use, device cleaning is a must (Cleaning
chapter).
5. Do a preliminary test on a small patch of
skin in the intended treatment area 48
hours prior to first use of sensiLight™ to
determine energy level settings for your
treatment (as depicted in the preliminary
test section).
6. sensiLight™ is suitable for men. However,
male body hair, especially on the chest,
will require more hair reduction sessions.

13
Preliminary test
The preliminary test is intended to
determine your skin reaction to sensiLight™
treatment and help you set the optimal
energy level for each treatment area.
Do a preliminary test on each area you
intend to treat 48 hours prior to the full
treatment.
Note:
Do not treat full areas with energy levels
that you have not tested before!
Do not treat the tested area for at least 1
week after the preliminary test is done.
1. Select the lowest energy level and deliver
a pulse on the selected preliminary test
skin area.
2. If you feel comfortable with the energy
level, increase it to level 2 and perform an
additional pulse on the next spot.
3. Only if you feel comfortable, you may
reach the maximum energy level of 3.
4. Stop the test once you do not feel
comfortable, as increasing the energy
level increases the risk of adverse effects.
5. If you see adverse effects such as severe
redness or blistering stop the test
immediately.
6. Wait 48 hours and examine the tested area.
If the skin in the test area seems normal
(no response or mild redness), you can
proceed with a full treatment in the highest
comfortable energy level that you have tested.
How to use sensiLight™ device
Note:
A preliminary test should be conducted
before proceeding to a full treatment. See
“preliminary test” section above.
1. To turn sensiLight™ on, press the ON/OFF
button (see image - item
1
). Energy level
1 green indicator will light on.
2. The device sets itself on the lowest energy

3. You may decrease or increase the energy
level according to your convenience
(to reach the level determined in the
preliminary test section). The energy level
lights will light up green on the level scale
according to the selected energy level.
4. Place sensiLight™ treatment window (see
image - item 7) on the desired body area

14
with full contact to the skin. If sensiLight™
is not properly applied or your skin tone
is too dark/tanned, the indicator light will
be“blinking” red. In this case, sensiLight™
will not trigger a pulse in that area of skin.
5. Press the trigger button (see image
- item 2) and hold it pressed for
continuous pulsing.
6. Press the trigger button once for single
pulse.
7. While pressing the trigger button, you
will see a bright flash, you will hear a
popping noise, and you may feel a mild
stinging and/or heat sensation.
8. Keep the trigger button pressed and start
moving the device with each pulse to
the next spot without detaching it from
the skin. The device will immediately
recharge and will be ready for the next
pulse. Repeat process until the entire
treatment area has been covered.
9. After the treatment, turn off the device
by pressing the“ON/OFF”button; an
orange indicator will light up while the
device is in the shutdown mode. Unplug
the unit after each treatment session.
Important notes:
• Try not to overlap pulses on the same
spot. Repeated pulses on the same spot
may cause burns.
• Do not treat the same area of skin more
than once per treatment as it may cause
skin irritation.
• sensiLight™ will not trigger a pulse if:
• There is no full contact of the
treatment window with the body skin.
• Your skin tone is too dark or tanned.
Recommended treatment
protocol
Typical sensiLight™ treatment
interval
While treating with sensiLight™, do not
overlap pulses on the same spot of skin.
• The first 1-4 hair removal treatments will
be approximately two weeks apart.
• The next 5-7 hair removal treatments will
be four weeks apart.
• Treatment 8+ hair removal treatments
will be as needed, until desire results are
achieved.

15
Plan your sensiLight™ treatment
Energy level should primarily be chosen
based on your own comfort.
The energy levels vary from level 1 to level 3
with a light fluence of 3-5 [J/cm].
Each treatment pulse should be applied
on different skin spot with no repetition
or overlap. The entire treatment area (legs,
arms, underarms, bikini lines, back) will be
determined by the user.
Notes:
1. Response to sensiLight™ hair reduction
differs between individuals, depending
on biological factors.
2. It may take up to 3-4 weeks before the full
results of sensiLight™ treatment can be
seen. The hair will continue to grow up to
two weeks after a hair reduction session.
However, thereafter as the hair grows
in three different stages the hairs will
naturally and gradually fall out depending
on the hair growth stage in during
which the treatment was done (only
hairs in the active growth phase will be
affected). Some hair may not be affected
by sensiLight™ because of the different
hair growth phases. To remove this hair
multiple treatment sessions are required
to reach the desired result.
3. The number of sessions required for
achieving long term results is different for
every treatment area and changing for
every user, as it is effected by type of skin,
hair and hormonal changes.
4. Maintenance will be needed from time to
time if growth is still visible.
5. You may use the treatment log at the end
of this User Guide, in order to assist you
with recording your specific treatments
areas, dates and duration.

16
What to expect when using
sensiLight™
During your hair removal treatment it is
normal to experience:
• A flash of light on each press of the
activation button. The light will not harm
the eyes when the device is applied
with full contact to the skin on the
recommended treatment areas.
• A pop noise with each pulse - occurs
whenever a pulse is activated.
• A sensation of warmth - radiates from the
light energy after each pulse.
• A mild stinging sensation - can be felt,
similar to being snapped with a rubber
band.
• Some mild red or pink color - appears
during and just after the treatment.
Post-treatment care
• Apply a calming lotion such as Aloe Vera.
• Avoid using peeling and bleaching creams
or products for at least 24 hours as this
irritates the treated skin.
• Avoid direct sun exposure for at least 2
weeks post treatment. If recently treated
skin is exposed to sunlight in this time
period, make sure to apply SPF 30 or
higher sunscreen.
• Do not wax or pluck hairs from treated areas.
Remember! It may take up to 2 weeks for
the hair to grow and be fully out if the hair
follicle is still active.
Cleaning and
troubleshooting
Cleaning
• Make sure to turn off and unplug unit
before cleaning.
• It is recommended to clean the treatment
window after every session by using a dry,
clean cloth to gently wipe the device.
• Keep sensiLight™ dry. Never place, store or
use sensiLight™ near bathtubs, showers,
basins or other vessels containing water as

Troubleshooting
If you experience any problems with
sensiLight™, please refer to below
information to try to resolve it.
• If sensiLight™ does not turn on:
• Make sure that the power supply is
plugged properly into sensiLight™
device and the electrical outlet.
• Make sure that the power outlet has
power.
• If sensiLight™ does not trigger a pulse:
• Verify there is full contact with the skin.
The trigger button will activate a flash
pulse only when the device is in full
contact with the skin.
• Verify that the area you are trying to
treat is not too small, curved or bony
to treat. You should get the whole
treatment window to touch the
treatment area (try to pull the skin flat).
• If the skin color level identified by
sensiLight™ is too dark, the flash
activation will be blocked.
• In case of safety issue or when the lamp
has reached its end, a steady red light
will come on. The device will shut down.
• General error:
• In case of dirt or debris is stuck on the
treatment window, you should clean
the treatment window according to the
cleaning section. If you can’t get the area
clean, contact our customer service.
• In case of delay in pulse readiness, you
should consider working on cooler
environment. The device may pulse at a
slower rate in a warm environment.
• In case of a general error, reset the
device – unplug the power cord from the
electrical outlet on the wall, wait 10 sec
and then reconnect it.
