Laser Hair Removal Fact!

Laser hair removal

No patient or operation is quite the same and so you may find that not everything below will apply to you. Nonetheless we hope that these answers to common questions and worries are helpful. Please ask you doctor or nurse if you are unclear about anything.

How does the laser treatment work?

The laser we use for hair removal is called an Alexandrite laser. Lasers work by delivering an intense beam of light that is absorbed by the skin. This light is converted to heat and is absorbed by the cells being targeted (hair follicle), while leaving the surrounding tissue unaffected. Laser is used to control hair growth, but the results are never permanent.

Due to the cycles of hair growth multiple laser treatments are required to provide long lasting reduction in hair growth, as the laser will only damage the follicles in the growth phase. It is difficult to predict individual responses as many factors are involved: the thickness of hairs, different sites on the body, hormonal differences, darkness of hairs and how strong laser light can be tolerated. However, in general the hair-free intervals gradually lengthen and the regrowth becomes sparser and finer.

What are the risks and benefits of having laser treatment?

Laser treatment may make the underlying skin colour darker or lighter. Any darkening (due to formation of brown pigment) usually fades over 6-12 months. If the skin is made paler, this may be permanent. The risk of pigmentation is greater with darker skin tones and tanned skin, which is why we can only offer laser hair removal to lighter skin types with no tan. Blistering and crusting of skin sometimes occurs. If this happens, you must not pick or scratch the area to avoid permanent scarring.
The laser beam will damage eyes if viewed directly without protection.

Is there any preparation I need to know about?

You must avoid bleaching, plucking or waxing the hair for 4-6 weeks before treatment. The melanin containing hair must be present in the follicle as it is the ‘target’ for the laser light. We know this may be difficult for you, but it is important for good results. If you shave, it is best to shave 2 days before treatment. Avoid the sun for 4-6 weeks before and after treatment, and during any treatment courses. You may develop hypopigmentation (white spots) after treatment if skin is tanned. The use of selftanning products must be discontinued one week before treatment. If you wear make up on the treatment area, please bring along the lotions to remove it. Treated skin must be clean and dry.
