An instrument, such as a diode laser is employed for destroying the hair follicles. The results of laser hair removal last much longer than any temporary hair removal method available in the market.
How Does Laser Hair Removal Work?
Laser hair removal heats melanin, which is the color pigment of the hair. Heating melanin damages the growing region of the skin. A numbing cream is massaged onto the skin before the process starts.
Although the success of laser hair removal depends largely on the expertise and skill of the laser operator and the availability and preference for various laser technologies, it is gaining great popularity because of its effectiveness and speed.
Side Effects To Be Aware Off
Laser hair removal is actually a very comfortable process as there are very little side effects associated with it. It does not damage the skin in any way. Before undergoing laser hair removal, a person should not wax, pluck or shave any hair from the desired area for weeks. One should refrain from applying any lotion or cosmetic on the skin on the day of getting the procedure done as it might cause unfavorable reactions.
Laser hair removal can make the skin red and sore for some days. This can be treated by applying cold compresses or ice packs to the skin. Although most people do not get bruised, it does happen in a few rare cases. However, the pain is not excruciating. Bruising is minimal and usually happens when tanned areas are being treated. This is because it becomes difficult for the laser to differentiate between the skin and the hair follicles.
Greater the difference in the color of the two, the easier it would be to undergo the process. Laser hair removal works better on people with light skin and dark hair than on people with brown or golden hair as dark colors absorb light. People with tanned skin should wait till their tan wear away.
Some people can experience pain during and after the procedure. However, this can be treated by using topical anesthetics. There is a possibility of the treated area getting swelled up for a few days. Applying ice to the skin after laser hair removal reduces the probability and intensity of side effects. Mild cleansers can be used to clean the treated area and it is best to avoid strong soaps. Sun exposure causes skin irritation.
One should always apply a sun screen on the treated area before venturing out in the sun. Repeated or over use of alexandrite or long-pulsed ruby lasers may lead to crusting but this can be treated with proper care after the procedure.
Precautions That Should Be Taken
Both the patient and the laser operator must wear safety goggles to prevent injuring the eyes. Tattoos darken the skin and so one should always consult a dermatologist before undergoing laser hair removal on a tattooed area.
Hyper pigmentation, which refers to darkening of the skin due to prolonged laser exposures, can be cured just by bleaching the area.
Most people can fearlessly undergo laser hair removal treatments but the ones with sensitive skin, allergies, having herpes or pacemakers implanted in them, should steer clear of the process. One should avoid laser hair removal during pregnancy.
A person should provide the treating professional with proper information about his or her medical history so that the latter gets to know of the former’s illnesses or allergies and can recommend medications accordingly. A cooling device cools the affected area by a contact chill tip during the entire laser hair removal process. A freezing spray protects the dermis.
Number Of Sessions Required
Hair grows in many phases such as catagen, telogen and anagen. Laser is effective only on the presently active hair follicles, i.e. anagen. That is why a number of sessions are necessary to get rid of hair in various phases of its growth. It takes four to eight laser hair removal sessions for a person to reduce unwanted hair but sometimes, one can require a minimum of seven sessions.
Clinicians usually recommend a gap of three to eight weeks between each session. The total number of sessions that a person must undergo is determined by parameters such as the roughness of hair, the color of the skin, the region of the body which is being treated, and the gender of the person. Since multiple sessions of laser hair removal are required to get the desired result, one should be disciplined enough to turn up for the sessions, timely.
Where And By Whom Should One Get It Done From?
Side effects of laser hair removal, although rare or minimal, do exist and it is the duty of the staff at the clinic to inform a person of the possible side effects of the treatment. If a clinic declares that there are no side effects involved in laser hair removal, then it is best not to undergo the procedure at that clinic.
An experienced laser operator can help prevent scars, burns and hyper pigmentation which can otherwise last for a lifetime. Based on the roughness of hair and the color of the skin, the proper source of laser with the appropriate wavelength must be employed.
A professional will understand the optimum level of light for each person. Too little or too much light can bring about side effects or unsatisfactory results. It is always advisable to consult a dermatologist before enrolling in a laser hair removal program.
Reason Behind Its Growing Popularity
Laser hair removal has been in vogue for a decade. With the development of technology, the procedure has now become very safe. Although some minor side effects can arise, a lifetime of good looking skin can undoubtedly be worth a few days of soreness. It would be wise for a person to do a bit of research and visit a certified clinic for laser hair removal which is well equipped with modern machines and facilities and has a well-behaved and experienced staff.
