Laser Hair Removal Overview

Dr. Bhavesh Shah, Dermatologist
Laser hair removal has come a long way since the first laser for hair removal received FDA clearance in the mid 1990s. Older generation lasers were slow, very painful and worked only on individuals with very dark hair and very light skin. Now there are varieties of laser hair removal specially designed for different skin tones, hair types, etc. It usually takes a series of treatments for permanent hair removal, but there’s a treatment out there for just about everyone. Types of Lasers used for hair removalNo single laser is ideal for every individual. Depending on your skin and hair colour, some lasers will be more effective than others. Diode LaserLonger wavelength allows deep penetration into the skin and safety for darker skin typesNot effective for lighter and finer hair Smaller spot size, which results in longer treatment timeThe longer treatment time necessary for diode laser hair removal  Nd:YAG laserCan be used on all skin types, including tanned skin Large spot sizes and fast repetition rates allow large areas to be treated quickly Provides less effective treatment for fine and light hairs than some other hair removal lasers Ruby LaserFirst laser introduced for hair removal Laser beam is well absorbed by melanin pigment in hair, making it good for removing finer, lighter hair Should be used for hair removal on patients with fair skin, as it may burn those with dark or tan skin Slow repetition rate and relatively small spot size, which may mean a longer, more expensive treatment with greater discomfort Alexandrite LaserThe fastest hair removal laser Large spot size (up to 18mm) and high repetition rate Can rapidly treat large body areas - an entire back can be treated in less than 30 minutes Suitable for patients with fair to olive complexions Intense pulsed light (IPL)Used for hair removal, but primary use is to treat skin pigmentation problems Unlike lasers, IPL devices emit the full spectrum of light wavelengths Works best on patients with fair skin and dark hair

Laser Hair Removal - Frequently Asked Questions

Dr. Nithya Raghunath, Dermatologist
In the past, the usual remedies for unwanted hair were plucking, shaving, waxing, or chemical depilatories. Some are painful, some are messy, and all are only temporary. Laser hair removal is an FDA-approved process of permanently reducing or eliminating unwanted hair on almost any part of the body except near the eyes. The process takes anywhere from several minutes to several hours, depending on the area of the body involved.What is laser hair removal?Laser hair removal uses a low-energy laser, which passes through the patient's skin, being absorbed by the pigment in the hair follicle. Each pulse of the laser targets and inactivates a large number of hair follicles. Approximately 3-6 treatments are necessary, although some people do require more treatments.Inadequately trained technicians can cause permanent scarring, hyperpigmentation and disfigurement. Always make sure the person who is performing any laser treatment has the required training and experience as well as the correct laser for your skin type and color. Popular areas of treatment include the brows, lip, chin, chest, shoulders, neck, back, legs, thighs, arms, underarms and ears.Is the hair removal permanent?During each treatment session, a certain percentage of the hair follicles are damaged such that hair will not grow from them again. With each treatment session, additional hair follicles are damaged until hair is completely absent in most cases.Is the treatment painful?There is some discomfort during laser hair removal, but the pain is generally less than waxing or electrolysis. Depending on how aggressive the treatment session is, the skin may be slightly to significantly pink following treatment. A certified dermatologist offers a potent numbing medication, which significantly dulls the pain. In most cases, no anesthesia is necessary.For maximal results, it is best to avoid bright sunlight for approximately 10 days prior to treatment. The area to be treated should be shaved immediately prior to the treatment. The aftercare is minimal. Sun exposure should be avoided for a few days after treatment.What are the risks and side effects of laser hair removal?The possibility exists that some side effects or complications can occur given various variables, including:NormalItching, during treatmentRedness for up to 3 daysSwelling (around the mouth) up to 3 daysPain, tingling, or feeling of numbnessRareCrusting/scab formation (on ingrown hairs)BruisingPurpura (purple coloring of the skin) on tanned areasInfectionTemporary pigment change (hypo-pigmentation or hyper-pigmentation)Side effects occur infrequently and, as a rule, generally are temporary. If any of the above last for more than 3 days, make sure to contact your doctor. The doctor needs to know in order to adjust settings on your following treatment.What are the stages of hair growth and how does it affect me?There are three phases of the hair growth cycle:Anagen (active) is the growing phase or when the hair fiber is produced. During anagen, the hair contains a great quantity of melanin, the pigment which gives your hair its color. This is the phase during which laser hair removal treatment is most effective.Catagen (club hair) is the period of controlled regression of the hair follicle. This phase is when the lower part of the hair stops growing, but does not shed, and the follicle is reabsorbed. It will be difficult for permanence to be achieved when the hair is in the catagen growth cycle.Telogen (tired) is the last of the hair growth cycle. In this resting phase, the old hair falls out in preparation for the development of a new anagen hair. Permanence cannot be achieved when the hair are in the telogen growth cycle.

Do's & Dont's After Tooth Removal

Dr. Swasti Jain, Dentist
1. TO CONTROL BLEEDINGBite firmly on the gauze for 45 minutes to an hour.Applying pressure over an extended period is the key.Don't keep changing the gauze, and don't chew on it. Just put it in place and close down, for the full 45 minutes to an hour.The blood clot that forms in the tooth's empty socket is an important part of the healing process, so be careful not to do anything that will dislodge or disrupt it.Avoid vigorous rinsing or spitting. - These activities may dislodge the clot.Don't disturb your extraction site. - Don't touch or poke at it with your finger. Don't explore it with your tongue.Don't consume hot liquids and foods. - Hot items, especially liquids like soup, tea, and coffee, tend to dissolve blood clots.You should avoid smoking or using a straw (these activities create suction). Also, don't blow your nose. And if you need to sneeze, sneeze with your mouth open. (See below for more details.)It's best to avoid strenuous work or exercise. 2. SWELLINGIt's common and normal for some degree of swelling to occur after having a tooth pulled. The amount that ultimately forms is typically proportional to the extent of the surgery that has taken place. That means:After very simple extractions you may notice very little, possibly none.With more involved cases (longer, more difficult extractions or the removal of several teeth) you may notice a pronounced enlargement, possibly involving a large portion of your face.Generally speaking, the amount of swelling that forms can be minimized via the application of ice packs on the outside of your face over the area where your surgery was performed, starting immediately upon the completion of your procedure.3. AVOID SMOKINGPeople who smoke tend to experience a higher level of complications with extraction site healing. That means if you can avoid smoking for the first 24 hours (and preferably 48 hours and longer) after having your tooth pulled, it will be to your benefit.4. AVOID BLOWING NOSEThat's because doing so can create a pressure difference between your mouth (via the recesses of your extracted tooth's socket) and your sinuses that might be great enough to disrupt what in some cases may be just a paper-thin layer of bone separating the two.5. EATING Take soft and cold diet for first 24 hrs.Try chewing from the other side of the extraction site.6. NUMBNESSAfter your tooth has been pulled, some portion of your mouth will still be numb, possibly for some hours. Besides just the area immediately surrounding your extraction site, this will likely include some aspect of your lips, cheeks or tongue too.This sensory loss can result in accidents. As examples ...You might unknowingly bite your lip or tongue while chewing, possibly even repeatedly.You might not be able to test hot (temperature) foods and beverages adequately, which could result in burns.
