red (hypertrophic) or large and extended beyond the injured area (keloid). More advanced
cosmetic treatment may be required to improve the appearance.
Change in pigmentation
This appliance targets the hair roots, in particular the pigmented cells of the bulb.
Nonetheless, there is a risk of temporary hyperpigmentation (increase in the brown
pigmentation or discolouration) or hypopigmentation (whitening) of the surrounding skin.
The risk of change in pigmentation is higher among people with darker skin.
Generally, the change in pigmentation and the discolouration are temporary. Cases of
permanent hyperpigmentation or hypopigmentation are rare.
Excessive redness and swelling
In some rare cases, treated skin may become very red and swollen. This reaction is more
common on sensitive areas of the body. The redness and the swelling should disappear
within 2 to 7 days during which you should apply ice to the affected area/s regularly. Gentle
cleaning does not pose a problem, but you should avoid any exposure to the sun.
Infection
A skin infection is extremely rare, but may occur after a burn or a lesion of the skin caused
by the appliance.
Bruising
Very rarely, using the appliance may cause some blue or purple bruising which could last 5
to 10 days. As the blue disappears, the skin may take on a rusty colour (hyperpigmentation)
that could be permanent.
