A person who chooses to have these hairs removed usually has excessive growth in undesirable areas or problems that arise from abnormal hair growth patterns on normal skin. Laser hair removal is gaining popularity due to its speed and effectiveness. Laser technology, for example, has been successfully applied in almost every industry.
People nowadays prefer painless non-invasive hair removal procedures. The introduction of ultra-technology brought a new wave in the laser hair removal technique as technology advanced. This is thought to be more secure and has fewer side effects. Another factor driving up demand for laser hair removal techniques is the high prevalence of skin disorders in developing countries.
What exactly is laser hair removal?
Laser hair removal is a medical procedure that uses a laser to remove unwanted hair. A light beam is used to destroy the hair follicle. It is one of the permanent hair removal methods. The number of hair regrowth cells in the follicular cells is steadily decreasing.
Laser hair removal principles of operation
Hair growth occurs in the skin’s follicular cells. Only these follicular cells are targeted by laser hair removal. The primary principle of laser hair removal is selective photothermolysis. It is basically matching a specific frequency of light with the pulse duration.
Melanin absorbs light energy and produces heat as a result. This heat is then transferred to the germ cell of interest. To destroy the targeted tissue, the optimal effect is required. The follicles’ basal stem cells are heated, causing localized damage.
What are the three major types of laser hair removal?
In this method, different wavelengths of laser energy are used. Its wavelength ranges from visible to infrared. One of the most important factors is matching duration to wavelength. This determines the heating rate, which is directly related to the laser’s follicle-damaging potential.
It is an abbreviation for neodymium-doped yttrium aluminum garnet. It’s unclear what it is. This complicated name is simple to remember. It is named after the laser technique that employs this Nd:YAG crystal as the medium. It is used differently depending on the type of skin and hair color. For patients with darker skin and black hair, for example, practitioners use a long-pulsed Nd:YAG laser with an effective cooling tip. This is regarded as both safe and effective.
A diode laser is used in this type of laser hair removal. A diode laser is essentially a single wavelength of light with a high abruption rate of the melanin pigment. It uses pulses with a high frequency and low fluence to deliver high energy to follicular cells.
Alexandrite Lasers are popular LASERs that emit light energy through an alexandrite crystal. The alexandrite laser emits energy at a wavelength of approximately 700-755 nm. This wavelength corresponds to the absorption spectrum of melanin. It is thought to be more effective on people with lighter skin. In this case, it outperforms both diode and Nd:YAG activity.
Which method is preferable: shaving, waxing, or laser hair removal?
There are three options available for removing body hair. Here’s a basic comparison of the three.
Shaving is the process of removing hair with a razor. It essentially cut the hair from the shaft to the skin. That’s why it’s only temporary. Waxing is another effective method for hair removal. This approach is more effective. There is no reason to wonder why. Because hair is pulled out near the roots during waxing. Because of this, it lasts longer than shaving.
Laser hair removal, on the other hand, destroys the follicular cells that are responsible for hair growth. Long-term and consecutive laser hair removal would undoubtedly permanently remove hair from the root of the follicles.
Be wary of laser hair removal side effects!!
Some patients may experience temporary rashes or burning sensations on their skin as a result of the medication. So, while there are some common side effects of laser hair removal, they are not life-threatening. Pink skin, redness, itching, and swelling near the treatment area due to follicle swelling are all common side effects of laser hair removal.
In severe cases, hypopigmentation or hyperpigmentation may develop near the treated area. However, the introduction of ultra-technology in laser hair removal equipment resulted in some more innovative laser hair removal equipment. This ensures that the burns and other skin allergies heal quickly with topical applications.
The overall picture
Because of the growing demand for non-invasive hair removal procedures, the laser hair removal market has been rapidly expanding. It is widely used in beauty clinics, salons, and dermatology clinics, as well as at home. As previously stated, laser hair removal is far superior to shaving and waxing for completely removing unwanted hair.
The practitioner employs various types of laser hair removal depending on the type of skin and color of the hair. When it comes to side effects, this treatment does have some, but they are not severe. It can be avoided or treated.
