Is there any part of your body that is beset with excessive hair growth where it should not be? Do you wish to save up on time (plus money!) and skip plucking, shaving, or waxing on a regular basis? If only that can be done!
No more wishful thinking because, thanks to aesthetic treatments and technology, hair growth can be radically reduced and removed with finality.
Let’s talk about lasers.
Lasers are powerful machines that are manufactured for a specific purpose. It is widely used in the aesthetic and medical industry to treat various conditions and diseases affecting the body.
For hair removal, lasers work selectively to remove hair by releasing a single energy-charged light beam that is focused on a specific area where unwanted hair is present. The energy from the light beam penetrates through the hair shaft, which eventually breaks down as its tinted pigment absorbs the concentrated light. As a result, hair is removed while leaving its follicle and the untreated surfaces of the skin undamaged.
Currently, there are 3 kinds of laser technology in use:
- Alexandrite Laser (755 nm)
- Diode Laser (800 – 810 nm)
- ND: YAG Laser (1,064 nm)
Each type of laser is designed to address hair removal basing on the skin tone and hair composition.
|Type of Laser||Hair Composition||Skin Tone|
|Alexandrite Laser||Dark hair, medium to coarse||Fair to mid-toned skin|
|Diode Laser||Dark, fine hair||Fair to mid-toned skin|
|ND: YAG Laser||Dark, coarse hair||Darker skin|
An Alexandrite laser uses an alexandrite crystal in emitting its red light beam. It is able to produce a specific wavelength of light that measures 755 nm long. The beam’s length is the measurement of how deep the laser light can penetrate into the skin.
Diode lasers generate light beams with the use of a semiconductor. Its reach ranges from 800 to 810 nm.
Short for Neodymium-doped yttrium aluminium garnet, ND: YAG is a type of laser that uses a crystal as a medium for light radiation emission. This laser is able to penetrate deeper into the skin’s layers, measuring up to 1,064 nm.
Using a laser as a means to remove hair has its advantages. These are:
- Its ability to remove hair selectively without damaging the surrounding areas of the skin.
- Its ability to significantly and permanently reduce hair growth of up to 90% with repeated treatments (6 to 8 sessions recommended).
- Its ability to let patients save on time, effort, and costs.
With advantages also come to the disadvantages. Lasers, unfortunately, are not perfect. These are some things that they could not do perfectly well:
- Completely eradicate hair growth after an initial session
- Get rid of lighter coloured hair (white or blonde)
Complications are rare but nevertheless may arise following laser treatment for hair removal. An example of which is skin discolouration or changes with pigmentation.
Lasers are generally safe when administered by an experienced and licensed doctor. Under no circumstance shall these powerful devices be handled by someone not trained for its use as its mishandling can cause serious damage to the skin.
The following areas of the body can be treated by laser to remove unwanted hair:
- Bikini line
- Brazilian area
Laser hair removal is safe for both men and women. On Edwin Lim Medical Aesthetic Clinic you can see how laser hair removal works and the differences from IPL treatment.
On average, the cost of a session of laser hair removal in Singapore ranges from $350 to $700.
Now that we have tackled the basics of lasers, let us move on to how a procedure is performed.
Before the start your laser hair removal treatment, the areas for treatment will be cleansed thoroughly and numbed with a topical anaesthetic. This is to ensure that the patient remains comfortable during the laser procedure. Once the anaesthetic takes effect, the laser device will be applied to the target areas. Patients may feel a slight tingling or prickling sensation when the laser touches the skin. The entire session is fairly quick. Depending on the size of the treatment area, the procedure may be done in 15 minutes to an hour. Patients are able to return back to their activities right after the procedure.
Following the procedure, you may notice some irregularities on the treatment sites. Your skin may appear bumpy or there may be slight inflammation and redness, but these should subside in a few days. Remember that your skin has been exposed to intense heat, so these are normal consequences.
Taking good care of your skin is essential after a laser hair removal procedure. Be sure to always clean the treated area with gentle cleansers, use proper sun protection and sunscreen (stronger SPFs are better) when you are out in the daylight. Your doctor may also prescribe medications for you to take as your skin heals.
Lastly, it is important to set proper expectations with the results of your laser hair removal.
I’ve mentioned earlier that not all of the hair will be removed entirely in just one session. Aside from that, there are also cases when the hair is not completely gone even after undergoing repeated treatments. Even though the hair is not fully removed, you can expect to see the lighter and thinner in composition, making them barely visible to the eye.
So, before committing yourself to a laser hair removal session, remember to discuss the process with your doctor thoroughly in order to avoid disappointments once your laser hair removal journey is finished.
