The Laser Hair Removal Pros and Cons You Should Know ...

If you have a darker complexion and want to ensure your treatment will be safe and effective, Dr. Yadav recommends asking your dermatologist about the possibility of using diode, alexandrite, or Nd:YAG lasers (a study on 150 people published in the journal Lasers in Medical Science found that 86% of participants'whose skin color ranged from light brown to deep brown'had no complications as a result of treatment with ''Nd:YAG lasers, and the small percentage of people who did have complications mostly experienced some hyperpigmentation that eventually went away).1 Alexandrite lasers might be best for someone with olive-toned skin and dark hair, Rachel Maiman, M.D., a board-certified dermatologist at Marmur Medical in New York City, tells SELF. 'That laser still relies on the presence of melanin pigment to destroy the hair follicle, which can result in pigmentary irregularities in patients of darker skin tones,' Dr. Maiman says. The diode and Nd:YAG lasers, however, have longer wavelengths and generally bypass pigment in the skin. For the darkest skin tones, Nd:YAG is considered the best option because it doesn't target melanin in the skin at all, Dr. Maiman explains.

When it comes to laser-induced skin discoloration, there are risk factors beyond having a naturally deep skin tone. Having sun-kissed skin from a recent vacation or summer of poolside lounging can create a higher risk of skin discoloration since there's a temporary increase of melanin, Dr. Maiman says. 'For lasers that rely on melanin as a recognized target, there's an increased risk that the laser will detect that pigment, resulting in heat energy delivered to skin instead of the hair,' she explains. In other words, it might be best to schedule your laser treatment before your big trip, and stay out of the direct sun (and wear sunscreen outdoors'but that's an always rule) as much as possible right before your appointment. If you happen to get a tan, let it completely fade before any laser hair removal, Dr. Maiman advises.

What are the pros of laser hair removal?

• While laser treatment doesn't get rid of hair forever (only electrolysis is approved by the U.S. Food and Drug Administration (FDA) for permanent hair removal), it does drastically reduce hair growth'to the point that many patients won't see any for months or even years, and the hairs that do crop up are often thinner and lighter in color.
• You can get it done anywhere on your body and the machine can cover large areas fast. Legs, back, underarms, bikini line, stomach, face'there's virtually no limit to the places you can get laser hair removal (if the laser you're using is safe and effective for your skin tone and hair color, that is). And no, there isn't a higher risk of side effects with laser hair removal in the bikini area compared to other areas, Dr. Maiman says.
• Depending on your hair type and the service area, it may actually not hurt too much. When it comes to pain level, for a lot of people laser hair removal falls somewhere between shaving (painless) and waxing (holy hell that hurts). Technicians typically use a numbing gel to help desensitize the area before and after the laser treatment to minimize discomfort. You might find that bikini and underarm laser hair removal is more painful because those are sensitive areas, Dr. Maiman adds. But in general, the treatment gets progressively less painful with each session, as the hair becomes finer, Dr. Charles says.

What about the cons?

• It's a long process. A session of laser hair removal on a small area like the underarms typically takes five minutes or less. However, it takes multiple sessions to see real results (typically between four and six, depending on the size of the area), and you generally have to wait six weeks between treatments.
• It's expensive. If you add up how much you spend on razors or bikini wax sessions in your lifetime, though, it might be worth the laser hair removal cost of about $300-$400 per session, per the American Society of Plastic Surgeons (not covered by insurance, unfortunately).
• Since the contrast between the color of the skin and the pigment in the hair follicle is what allows the laser to easily know what to target, laser hair removal works best on fair skin with dark hair, and is not as ideal for darker skin, as discussed above, or lighter hair, regardless of skin tone, Dr. Maiman says. If you have light blonde or white hair, the laser might not be as effective at targeting those hairs, studies show'you might see a reduction in hair growth, but not to the extent that's typically seen in folks with more contrast between their skin and hair color. Certain lasers, like the Nd:YAG, are better at distinguishing between hair and skin on all skin types, including light hair and dark skin.2
• Laser hair removal probably isn't a good idea if you're pregnant. 'Although lasers have been safely used to treat medical conditions like kidney stones and genital warts in pregnant people, there's no safety data presently available to support using lasers for cosmetic procedures like hair removal,' Dr. Maiman explains. Many doctors advise against undergoing cosmetic laser treatments while pregnant, in case of fetal risks, she adds. So if you're pregnant, or possibly going to be in the next couple of months, you may want to postpone your laser hair removal appointment until a later date.
• If done by an untrained technician, laser hair removal could leave burns or scars on the skin. Unfortunately, licensing procedures vary from state to state, and sometimes there are no requirements at all. Beware of 'laser centers,' since some states don't have licensing requirements for laser hair removal providers. If you're set on going to a spa, make sure it's a medical spa or laser hair removal center run by a doctor who's board-certified in an aesthetic specialty such as dermatology or plastic surgery, and has specific laser certification (even board-certified doctors who want to provide laser hair removal treatments need further training), Dr. Maiman advises.

Your armpits, your legs, your bikini line ' many women like it when these areas are soft, smooth and especially hair-free. Some women also take on facial hair. But what is actually the best way to depilate yourself and how do you permanently remove unwanted hairs?

Shaving is still one of the most commonly used ways to depilate. Several types of razors are available at the drugstores. These can render your legs, armpits, and bikini hairless in no time.

In principle, it is done quickly. Just use a razor blade on your skin under the shower and Bob's your uncle. A razor blade is also very easily fitted into your toilet bag and is inexpensive.

Disadvantages: The blades easily cause skin irritation and you may suffer from ingrown hairs. Moreover, the result is short-lived. After a day or two, the first stubble appears and you have to go at it again.

According to the British Association of Electrolysis, 'For over 100 years, electrolysis has been recognised as a safe, reliable method of treating all skin and hair types.'

When epilating, the hairs are removed from the skin with their roots. Epilating with tweezers is mainly applied to the eyebrows. For epilation, you can use a special epilation device. Resins and waxes are also a form of epilation. The hairs stick in the resin/wax and are then pulled out of the skin with strips.

Advantages of epilation: The hairs stay away for a few weeks, and when they grow back they do not form 'stubble'. You have less chance of ingrown hairs.

Disadvantages of epilation: this method is not completely painless. One endures it better than the other. You can also suffer from skin irritation and a burning sensation afterwards. In addition, the hairs must be long enough to be 'caught'. You will need to grow enough hairs first. Especially in the summer, this is not always convenient.

The laser is a method of stopping unwanted hair growth (as good as) permanently. When using the laser method, the hair papilla is destroyed by the laser light. As a result, hair cannot grow anymore. This technique only deals with hairs that are in the growth phase (hair growth expands in different stages). Because not all hairs are in the same phase at the same time, you will need to repeat the treatment a few times.

Advantages of the laser method: The method is not very painful and gives a good result. Afterwards, the skin may feel somewhat burning. The hairs usually do not return.

Disadvantages of the laser method: Purchasing a laser device is not cheap. This also applies to treatment with a beauty specialist or another provider. Lasers also have less effect on grey, red and blonde hair, and also work less well in people with dark skin. Keep in mind that the treated skin is not allowed in the sun for a few weeks after the treatment.

New alternatives to lasers are IPL (intense pulsed light) and ELOS (electrical optical synergy). These methods resemble lasers but work slightly more intensively because of pulsating light (IPL) or the simultaneous use of radio frequency radiation (ELOS). This eliminates hair papilla in several ways, which would give a better result.

Advantages of IPL/ELOS: On average, about 75% of the hair is permanently eliminated in the treated area. Keep in mind that there is always some down hair that can sometimes grow into 'real' hair. Especially the ELOS treatment is also suitable for lighter hair and for people with dark skin.

Disadvantages of IPL/ELOS: You cannot perform this method yourself, you need to go to a (beauty) specialist. If performed incorrectly, the skin may burn, temporarily discolour or form scars. Always have your treatment done by a professional company. You have to take into account slightly higher costs than other hair removal methods.
