Laser Hair Removal: Working Principle And Safety

Dadu Medical Centre offers the advanced state of the art and Best Laser Hair Removal Treatment in Delhi and helps both men and women to achieve smooth and hair-free smooth skin.

Laser hair removal is an extensively practiced cosmetic procedure to remove unwanted or excessive hair from any part of the body or face. The most targeted areas include the chin, upper lips, underarms, arms, chest, bikini line, legs, and back. It is a speedy, hassle-free treatment involving focusing laser light pulses on undesirable hair to significantly delay hair growth in the long term. Young men and women belonging to ages 20 to 45 usually undergo this treatment at Dadu Medical Centre, performed by the Best Doctor for Laser Hair Removal in Delhi.

Laser hair removal provides the best and most precise outcome for people who have fair skin and dark hair. But, with advancements in laser technology, this limitation has been removed. It works only on actively growing hair, hence multiple sessions are required followed by maintenance sessions to achieve silky, smooth hair-free skin.

The Mechanism Of Action Of Laser Hair Removal

Human skin is composed of a thin, outer layer called the epidermis and a thick, inner layer known as the dermis. The roots of the hair are situated inside the hair follicles of the epidermal cells that go further down into the dermis. Hair strands grow out from within the hair follicles. The hair color that people naturally have are because of the melanin pigment within the hair which is released by the melanocytes located in the hair bulb.

During a laser hair removal session, the hair removal laser device emits one or more pulses of high-intensity infrared radiation. These pulses travel through the skin down the hair and are absorbed by the melanin pigments in the hair follicles. Melanin is the natural pigment in the hair responsible for imparting its color. The laser generates heat which specifically destroys the hair follicles without harming the surrounding healthy skin.

Typically, the lasers used for hair removal nowadays are neodymium: yttrium-aluminum-garnet (Nd: YAG) which operates at 1064nm; diode laser operating at 800–810nm; or the alexandrite laser at 755nm, all of which emit highly-concentrated infrared radiations.

They are chosen over the other laser devices because the infrared radiations are capable of destroying the hair by the selective photothermolysis principle. According to this principle, when the laser light is directed onto the skin, only the dark-colored skin tissues absorb the light, be heated, and get destroyed or damaged rather than lighter-colored skin tissues. The dermal papilla cells in the hair roots that are actively dividing are more susceptible to thermal injury by laser and are destroyed. As the laser light is delivered in brief pulses, the light penetrates the skin with minimal absorption by the melanin of the normal, untanned/white skin and gets only minimally damaged.

At Dadu Medical Centre, Dr. Nivedita Dadu, the Best Doctor for Laser Hair Removal in Delhi offers the best treatment for laser hair removal and uses the most advanced treatments for removing unwanted hair safety.

How safe is laser hair removal?

Laser hair removal is an FDA-cleared and clinically tested treatment known since the mid-1990s and can be applied to all skin types. It is a safe and effective hair removal method performed by certified dermatologists, who are highly skilled in using lasers, in their clinics. When unqualified or inexperienced technicians perform laser hair removal on the patient skin which is tanned or naturally dark, there are chances of complications. The immediate side effects of laser hair removal sessions include first-degree burns; secondary/third-degree burns that may lead to blistering, scarring, skin pigmentation issues; herpes outbreaks, and infections. However, to avoid overheating or burning of the skin some laser devices are already equipped with cooling systems. There is a variety of methods to soothe the skin during or after lasers such as ice packs, cooling gels, very low-temperature sprays, cold glass containers, and cold airflow.

While performing laser hair removal, both the laser device service personnel and the client must protect their eyes with special eyewear. The medical expert at Dadu Medical Centre, a laser clinic in Delhi first does a patch test for lasers on the client’s skin to set the right intensity and duration of exposure and ensure that the client does not have to deal with any complications.
