The laser hair removal and pulsed light hair removal are methods of permanent hair removal. The methods based on laser or light are sometimes called photo-depilation.
Some machines use a lamp called xenon flash lamp that emits a spectrum of light (intense pulsed light or IPL).
Treatments with the lamp flash are sometimes referred to as laser hair removal but don't really have the results as laser.
The basic principle of laser hair removal is the "selective thermolysis". The laser causes damage in localized areas by burning and emitting black hair without burning the rest of the skin. The light is absorbed by the black areas called chromophores.
The laser hair removal targets melanin mainly. There are two types of melanin: eumelanin (which gives black hair) and pheomelanine (which gives red hair, the color of Asian skin and freckles).
If the hair contains less melanin, the laser is less effective. It is for this reason that people with gray, red or blonde hair are not good indications for laser hair treatments.
On the other hand, if the skin contains more melanin, the chances are lower that the laser can make the difference between the skin and hair.
For this reason, black people can not use this technique.
A light skin and dark hair is the best combination for laser removal.
For other photo types, the only solution is the electric depilation.
Laser technology is used for a growing number of beauty treatments including hair removal, the relissage of the skin to reduce wrinkles or treat scars caused by acne, removing blemishes and pigment processing vascular lesions. It also uses laser to remove tattoos.
If you plan to use one of these techniques, it is important that you examine the risks and potential benefits.
The hazards and the effects of laser hair treatment:
Even when the laser is chosen for a given treatment, there is a risk of temporary as an immediate pain, reddening of the skin, bruising and swelling. Some lasers are equipped with cooling devices to reduce the risk.
Other side effects may also occur as the formation of blisters, burns and infection. In some cases the skin may become lighter or darker, but these complications are rarely permanent.
If the laser is not well chosen or that the technique is not well done, the results could not be obtained and a permanent scar may form. There is also a risk of eye damage if you do not protect adequately the eyes during the laser treatment.
For hair removal, the laser targets the melanin of the hair follicle. For the reduction of wrinkles and the treatment of scars caused by acne, the target device damages the cells that are near the surface of the skin. The results are similar to the tightening of the skin obtained with conventional techniques for relissage of the skin, such as chemical peeling and mechanical abrasion.
The main side effect is the risk of burns if you are tanned when the laser heats the surface area of skin rich in melanin. That is why it is not right to follow the laser treatment sessions without sun protection.
Our advice to limit the dangers of your laser hair removal:
• Make sure that the person operating the laser has the training and experience required for the efficient and safe removal.
• If you use laser hair removal, no tan before and after treatment.
• Make sure you protect your eyes, and ask questions about cooling the skin during laser treatments.
• Make the right choice of hair removal according to your skin and the area.
• Check the wavelength of the beam of energy that targets the tissue and the power setting of the device.
This technique is also not recommended for people with hormonal imbalance.
The results of laser treatments are not guaranteed:
The aesthetic laser techniques can be costly and you may be disappointed with the result if you are not a good candidate or if you have unrealistic expectations. For example, hair removal is more effective in people who have fair skin and dark hairs. This technique is not so effective in people with blonde, red, gray or white hair or the ones with dark skin. Most people must pay for multiple sessions to get good results. According to the operator and the type of laser used, the hair removal could be permanent (30%), but there is no guarantee that the technique will work for everyone or all parts of the body.
