Know All About Permanent Laser Hair Removal

Know All About Permanent Laser Hair Removal by Sarah Buchanan

Today permanent laser hair removal is now the second most common cosmetic procedure in the world. It has been used to help both those who are experiencing excessive hair growth because of illness, and those who are genetically predisposed to it. Actually laser hair removal is a technique that uses to remove unwanted hair form your body and face. The laser hair removal technique comes in use in 1990. Newer lasers remove hair from your body safely, affordably and effectively. It's not an issue what type of skin you have. The common philosophy about laser hair removal is that it is permanent to remove hair, but doesn’t work on every body

The hair removal method like waxing, shaving and plucking from your body are not permanent and also these are uncomfortable, time consuming and expensive. After a day later they return back so you may be interested in laser hair removal. There are a wide variety of laser technologies out there, and they are not all created equal. There are Alexandrite lasers, Ruby lasers, nd: YAG lasers, Diode Lasers, and Intense Pulse Light systems, which are not lasers at all but approach the problem in a similar manner. Some systems are better or worse for different skin types or hair colors, so be sure to ask your laser skin care professional in the equipment they use is well suited to give you the result you are looking for.

Lasers are designed to target the cells of the hair follicles without causing harm to any nearby tissues. Short pulse lasers will heat the target cells less than long pulse ones, and are less likely to cause thermally-induced skin scarring, one of the possible effects of laser hair removal on the skin. There are also lasers controlled by automatic scanning which limit the range of the pulses to the correct areas.

The aim is to destroy the target cells while avoiding harm to the surrounding tissue. Short pulses reduce the amount that the damaged cells heat up, thereby reducing thermal injury that could result in scarring. Automated scanners aim to reduce the chance of overlapping treatment areas.

If you have dark skin, laser hair removal can cause discoloration unless you use a specific machine created for dark skin. Lasers use pulse light to break down and target the dark pigment in your hair referred to as melanin. Lasers target the melanin in dark skin, which can cause discoloration. Hair growth progresses in three phases, growing, resting and shedding. Lasers and pulsed light target hair in the growth phase.

Some Possible Effects of Permanent Laser Hair Removal Technique:
1) The new hair growth after laser is may be thinner and the color is different from the original hairs. New hair may be growing in the area near by to the treated areas.
2) Redness for up to 1-4 days. Swelling and feel pain for up to 2- 3 days. Infection, scab formatting and crusting is also the type of side effects which a person faces after laser hair removal.
3) Laser hair removal can cause a temporary increase in skin-darkening pigments, especially in those who have naturally dark complexions or tan frequently. But the darkening can be lightened easily with skin bleaching products.
4) One of the more serious effects of laser hair removal on the skin is blistering. Blistering most often occurs in patients with the darker skin which demands higher laser exposure. To prevent blistering these patients should have their treated skin tissues cooled with a contact chill tip. Blistering, thanks to various new cooling techniques, is almost non-existent.
