How Philips’ Intense Pulsed Light technology works
Hair growth
Hair growth differs from person to person, depending on age, metabolism
and other factors. However, everyone’s hair normally grows in 3 phases.
1 Growing phase (anagen phase)
The hair grows actively from the root. In this phase the concentration of
melanin is highest. Melanin is responsible for the colour of the hair. Melanin
concentration is also the determining factor for the efficacy of the Intense
Pulsed Light technology. Only hairs in the growing phase are susceptible to
treatment with light.
2 Degradation phase (catagen phase)
Hair growth stops and the root shrinks before the hair sheds.
3 Resting phase (telogen phase)
The old hair is shed. The follicle remains at rest until the biological clock
tells it to become active again and grow a new hair.
Working principle
- The appliance works by heating up the hair and root beneath the skin.
The melanin in the hair and hair root absorbs the energy from the
light pulses. The darker the colour of the hair, the more light will be
absorbed. This process stimulates the hair to go into the resting phase.
- In between treatments, hair sheds naturally and regrowth is inhibited.
After the treatment, i t can take one or two weeks for the hair to shed.
- Optimal hair reduction cannot be obtained with a single session, since
only hairs in the growing phase are susceptible to treatment with light.
During a treatment, hairs on the treated area are usually in different
stages of the hair growth cycle. To effectively treat all hairs you have to
repeat the treatment once every two weeks for the first two months.
An integrated optical filter ensures that no UV light reaches the skin
and ensures that the appliance is safe for the skin when used according to
the guidelines.
