Hair removal with light is one of the most effective methods to get
rid of unwanted body hair with longer lasting results. It is completely
different from current home hair removal methods and Philips has been
investigating this method together with leading dermatologists for almost
10 years. You can now use this innovative technology comfortably in the
privacy of your own home, whenever you want.
This appliance is intended for removing women’s body hair on areas below
the neck:
underarms
bikini area
legs
The appliance is not intended for:
persons with a too light body hair colour (light blond, red, grey or
white body hair) or a very dark skin. See chapter ‘Preparing for use’,
section ‘Setting the light intensity’.

how photo-epilation works
hair growth
Depending on age, metabolism and other factors, everyone’s hair grows
differently, but hair normally grows in three phases:
1 Anagen phase (growing phase)
The hair grows actively from the root. In this phase the concentration
of melanin is highest. Melanin is responsible for the pigmentation of the
hair. The more melanin there is in the root, the darker the hair is. Melanin
concentration is also the determining factor for the efficacy of this method.
Only hairs in the anagen phase are susceptible to treatment with light.
2 Catagen phase (degradation phase)
The hair growth stops and the root shrinks before the hair sheds.
3 Telogen phase (resting phase)
The old hair separates from the root and the new hair slowly pushes out
the old hair. The root remains at rest until the biological clock tells it to
become active again and grow a new hair (4). Hairs on an area of skin are
usually in different stages of the cycle of hair growth.
Working principle
The appliance removes hair by heating up the hair and root beneath the
skin. The melanin in the hair and hair root absorbs the released light pulses.
The darker the colour of the hair, the more heat can be produced. This
process stimulates the hair to go into the resting phase.
The hair now sheds naturally and the hair growth is inhibited.
Optimal hair removal cannot be obtained with a single session, since only
hairs in the anagen phase are susceptible to treatment with light. During
a treatment, hairs on the treated area are usually in different stages of the
cycle of hair growth.
To treat all hairs successfully and to prevent the hair root from becoming
active again, the treatments have to be repeated once every two weeks.
