The informations about laser hair removal treatment.
Laser hair removal is a medical procedure that uses a concentrated beam of light (laser) to remove unwanted hair.
During laser hair removal, a laser emits a light that is absorbed by the pigment (melanin) in the hair. The light energy is converted to heat, which damages the tube-shaped sacs within the skin (hair follicles) that produce hairs. This damage inhibits or delays future hair growth.
Although laser hair removal effectively delays hair growth for long periods, it usually doesn't result in permanent hair removal. Multiple laser hair removal treatments are needed for initial hair removal, and maintenance treatments might be needed as well. Laser hair removal is most effective for people who have light skin and dark hair, but it can be successfully used on all skin types.
How you prepare
Before laser hair removal, schedule a consultation with the doctor to determine if this is an appropriate treatment option for you. Your doctor will likely do the following:
Review your medical history, including medication use, history of skin disorders or scarring, and past hair removal procedures
Discuss risks, benefits and expectations, including what laser hair removal can and can't do for you
Take photos to be used for before-and-after assessments and long-term reviews
At the consultation, discuss a treatment plan and related costs. Laser hair removal is usually an out-of-pocket expense.
The doctor will also offer specific instructions to prepare for laser hair removal. These might include:
Staying out of the sun. Follow your doctor's advice for avoiding sun exposure before and after treatment. Whenever you go out, apply a broad-spectrum, SPF30 sunscreen.
Lightening your skin. Avoid any sunless skin creams that darken your skin. Your doctor might also prescribe a skin bleaching cream if you have a recent tan or darker skin.
Avoiding other hair removal methods. Plucking, waxing and electrolysis can disturb the hair follicle and should be avoided at least four weeks before treatment.
Avoiding blood-thinning medications. Ask your doctor about what medications, such as aspirin or anti-inflammatory drugs, to avoid before the procedure.
Shaving treatment area. Trimming and shaving is recommended the day before laser treatment. It removes hair above the skin that can result in surface skin damage from burnt hairs, but it leaves the hair shaft intact below the surface.
What you can expect
Laser hair removal usually requires two to six treatments. The interval between treatments will vary depending on the location. On areas where hair grows quickly, such as the upper lip, the treatment might be repeated in four to eight weeks. On areas of slow hair growth, such as the back, the treatment might be every 12 to 16 weeks.
For each treatment you'll wear special goggles to protect your eyes from the laser beam. An assistant might shave the site again if necessary.
