Frequently Asked Questions
The energy from the light source is taken up by the pigments (melanin and Haemoglobin) in the skin, hairs and blood vessels. Selective filtration makes the energy uptake specific for melanin (600 to 950 nanometers) or haemoglobin (530 to 950 nanometers); thus the system can be used for hair removal, vascular lesions and pigmented lesions. Hair removal is accomplished by the generation of heat from light in the melanin, which is then transferred to the hair follicle (root).
Pulse times of this applied light have been chosen to destroy the hair follicle by heating for at least 1 millisecond (one thousandth of a second) to 70 degrees centigrade.
Hair removal:
Dark hairs are most easily treated due to the large concentration of dark melanin
in these, which gives maximum absorption and conversion of light energy to heat.
Very fair hair has less melanin and consequently less heat is produced making it
slightly less certain of permanent destruction of the hair follicles. Grey (white)
hair has almost no melanin and cannot be efficiently treated. The upper skin layer,
of the epidermis, also contains melanin and the concentration increases when the
skin is exposed to UV light. It is therefore necessary to treat dark skinned and
tanned individuals with less energy to avoid generation of excess heat and pain in
the skin. The Pulsar computer has pre-
It is necessary to apply a thin layer of gel to the skin prior to treatment to assure an optimal optical transmission of light from the applicator to the skin.
How is the treatment carried out?
The Applicator (hand-
As the light energy is absorbed by the pigments (melanin and haemoglobin), the pain depends upon the concentration of melanin in the epidermis and the hairs combined. Consequently it hurts more in dark skinned people and those with dense, dark hairs. No anesthesia is required and most patients describe the pain as moderate and acceptable (as if a rubber band is snapped against the skin).
Does the patient need to shave prior to treatment?
Hairs should be 1 to 2mm long when the patient comes in for treatment so it is possible to mark out the treatment area. Long hairs take up the energy and prevent all of it reaching the hair follicle. Therefore hair is trimmed just before treatment for maximum transmission of the energy. If the hair is normally shaved and can be seen when shaven then patients can shave right up to the day of treatment although plucking and bleaching should not be done. By avoiding epilation and waxing 4 weeks before treatment it ensures as many follicles as possible contain a hair and thus can be destroyed by the light.
Why do hairs 'grow' after treatment?
Contrary to other treatments, hairs are not vaporized by the Pulsar treatment the hair follicles are killed by the heat but the hairs remain in the skin and often become attached to the epidermis. They will fall out after 1 to 3 weeks as the epidermis is renewed. During this period it will seem that the hairs are growing as the epidermis pushes them out.
How can you tell if the treatment has worked when the hairs are not removed immediately?
After treatment the hairs are often loose within the follicle and can easily be pulled
out with tweezers. A red ring around each follicle is often seen a few minutes after
treatment. These two things are good indications that sufficient heating of the follicles
has taken place. Unfortunately they are not always seen and we have seen many patients
with successful treatment results without the post-
The facial treatment usually takes 10 minutes whereas both legs and/or an entire back take approximately 1.5 to 2 hours.
The visible light is completely safe so no special precautions are needed apart from glasses for the brightness. The skin of some patients becomes quite red immediately after treatment and very rarely small blisters as from excessive sun exposure can occur. However, most patients experience no side effects at all and the described skin reactions above usually disappear within hours to a few days.
Unlike electrolysis the Pulsar treatment is non-
How many treatments are necessary?
Only hair in the growth phase can be treated. The number of hairs in this phase varies
from 10 to 70% depending on the body site. The lengths of the growth cycles also
vary. For most patients (unless there is a hormone imbalance) up to eight treatments
with a two to three month interval is sufficient to remove virtually all hairs on
the body. Facial hair may require more treatments. After the first treatment most
patients get a significant reduction in hair density also new grown hairs tend to
become finer. It is important to know that the first treatment is believed to synchronize
the anagen (growth) phase of the non-
How do I prepare for treatment?
Patients should avoid tanning 1 month ahead of and during the entire treatment scenario
to avoid excessive discomfort from excessive light absorption in the epidermis. Immediately
after the treatment the skin is particularly sensitive to UV light and strong sunlight
should be avoided for 4-
Please do not apply Deodorant, Perfumed products or Aromatherapy products on treatment day.
Most authorities would agree that by using intense pulsed light technology it is possible to permanently remove hair. Histology studies have found destroyed and denatured hair follicle cells post treatment. A recent study showed that the percentage reduction in hairs after one treatment at 9 weeks was 52.6%.
