What is i-Light?
i-Light is a home-use device for the removal of body hair using Intense Pulsed Light (IPL) technology. This is
the same technology used in professional hair removal salons and clinics. If used correctly it can provide
long-lasting hair reduction.
What is Intense Pulse Light (IPL) and how does the i-Light work?
i-Light works by directing an extremely short, intense pulse of light into the skin. The light energy is
absorbed by the melanin in the hair follicle temporarily disabling the growth mechanism in the hair and
delaying hair growth.
Hair follicles typically pass through three phases throughout the hair growth cycle. These phases are:
Anagen Phase (growing phase)
– the active growth phase of the hair follicles. Melanin concentration is at
its highest as it is responsible for pigmentation of the hair. Only hairs in the anagen phase are susceptible to
treatment with IPL (fig. 2).
Catagen Phase (degradation phase)
– this is a short transition stage, which follows the anagen phase and
signals the end of active growth of hair. It typically lasts 2-3 weeks (fig. 3).
Telogen Phase (resting phase)
– the hair follicle is completely at rest during this phase, which is the
longest phase and lasts about 100 days. During this time, the new hairs push out the old hairs, allowing the
growth cycle to begin again (fig. 4).
What to expect from i-Light
Our studies have shown significant hair reduction after only a single treatment. However, optimal results are
generally not obtained with a single session. For best results, repeat a treatment session whenever you
notice hair starting to regrow. Results vary by individual, however, most will re-treat areas every two weeks
for three treatments until desired results are achieved.
A few days after the first treatment you may start to notice hair has fallen out.
Some hair growth will occur that is less dense, finer and lighter in colour than the than the original hair.
This regrowth is perfectly normal and should be expected.
