Is Laser Hair Removal Suitable For Everyone?

Laser selective photothermal effect plays a decisive role in hair removal. As the fundamental theory for diode laser hair removal function, laser selective photothermal makes the target tissues show perfect absorbency to a specific wavelength. Treatment time for each pulse should be equal to or less than the target issues' thermal relaxation time. Thus photothermal effects will be limited in target tissues, and prevent thermal energy's damage to surrounding tissues.

Fortunately, for all types of skin and hair, laser hair removal has never been safer or more effective. Next, the laser diode machine manufacturer will share it with you.


Is laser hair removal safe for everyone?

While the latest lasers are able to more accurately distinguish deep follicle pigment from light skin pigment, people with darker skin tones should still take extra precautions when researching practitioners and the lasers they use. 

In patients with darker skin color, melanin is scattered in the upper layers of the skin, which will compete with the melanin in the hair to absorb laser energy. This can be avoided by making sure the right laser at the right wavelength is applied to your skin tone.

Dr. Simmons-O'Brien says, "For darker skin types4 to 6, they have ideal wavelengths because they bypass melanin in the skin and target collagen in the mid to deep dermis, either in the hair follicles or underneath." She adds that dark-skinned patients should not only confirm ahead of time that the dermatologist they want has a modern laser treatment, but should also ask their dermatologist to perform spot treatments first to see how their skin responds and heals.


How should I prepare for my appointment?

Most dermatologists will ask you to shave the area you want to treat 24 to 48 hours before your session begins to ensure that no hair is visible, thus minimizing the possibility of inflammation. It is also important to avoid shedding and tanning prior to application, which can make the skin more sensitive.

 

In addition, people with darker skin tones should stop using all acid-based cleansers, peels, and topical classes of vitamin A four to five days prior to treatment. Dr. Simmons-O'Brien says that vitamin C or any other whitening products should also be avoided two days prior to treatment.

 

How painful is laser hair removal?

Dr. Frank says, "For the most part, no gel or topical anesthesia is needed. It's a relatively routine, painless procedure."

Dr. Simmons-O'Brien says, "Even with the proper laser settings, darker skin still retains more heat than lighter skin [tones]." She recommends that topical steroids should be applied to the treatment area after the procedure followed by an ice pack for 10 to 15 minutes to cool the skin.

 

But regardless of your pain tolerance, the good news is that depending on the body part, appointments are usually quick, averaging about 10 minutes for underarms, and about 30 minutes for legs and back, according to Dr. Frank.

 

How long does it take to see the results?

You will see a significant difference in hair regrowth after the first contact. But remember, this is not a one-and-done deal. A good rule of thumb is to expect one session per month for five to six months, depending on your hair type, with hair becoming thinner after each subsequent session. However, it is important to keep your expectations in check as the procedure is only approved by the FDA to permanently reduce hair loss.
