If removing unwanted body hair looks like a never-ending task, opting for laser hair removal will help achieve a permanent solution. Though not an instant cure, employing laser hair removal technology<\/strong> repeatedly will make your body hair lighter and scantier [1<\/a>]. Laser hair removal treatments are an apt solution if you wish to have a beach-ready bikini line, smooth face or silky legs forever. To get the desired results after every laser session, it is imperative to consult a reputed skin clinic with licensed dermatologists.<\/p>\n

About Laser Hair Removal Technology<\/h2>\n

The hair removal process backed by laser technology employs specialized laser beams focusing on the treatment area to vaporize unwanted body hair through repeated sessions. Laser light is used to remove the hair permanently by focusing on the hair follicle and the shaft to inhibit its growth and lower melanin production [2<\/a>]. Laser light works by targeting the pigment called melanin present in the follicles of your body hair to burn it to the root [3<\/a>]. So, there are no chances of hair regrowth in future. As laser hair removal procedure targets the melanin pigment, specific types of lasers might not be suitable for some hair types or skin tones [4<\/a>].<\/p>\n

Types of Lasers Used and Their Effectiveness<\/h2>\n

There are five types of lasers used for hair removal, which are safe and effective. Though each laser type is unique, all rely on a single principle, which is the conversion of light energy into heat to get the desired effect [5<\/a>]. These lasers are designed to target unwanted body hairs with varying textures and skin colour without damaging the surrounding skin. Irrespective of the laser type used for hair removal, no recovery period or painful process is involved.<\/p>\n

Type 1: Intense Pulsed Light or IPL for Hair Removal<\/h3>\n

Intense Pulsed Light hair removal treatment involves eliminating unwanted hair using an infrared device targeting the treatment spot with a single-spectrum light. This broad laser type with different wavelengths offers more coverage and removes scattered hairs. So, IPL is useful for removing thick and dark hair [6<\/a>]. You will feel the sensation of an elastic band snap during IPL sessions when the broad spectrum light passes through the skin to lock your hair’s melanin while its heat energy destroys the follicles. As the IPL initiates pulsating thermal energy during photothermolysis, melanin absorbs it quickly. The advantage of using Intense Pulsed Light hair removal treatment is that it comes with customizable pulse duration, energy levels, and wavelength [7<\/a>]. When compared to other laser treatments for hair removal, IPL might require you to attend several sessions, as the light beam is not focused. This laser type is ideal for removing hair in large skin areas without concerns about damaged tissues, as it doesn\u2019t penetrate deeper.<\/p>\n

Type 2: Ruby Laser for Hair Removal<\/h3>\n

It is one of the first types of laser used for cosmetic hair removal that is performed by emitting a ruby-coloured laser light with a short wavelength. This hair removal procedure utilizes 694 nm of short wavelength to focus on the follicles of facial<\/a> <\/strong>and body hair. It ensures that the surrounding skin structure and tissue are intact. It is a painless and low-risk option that can get rid of unwanted hair permanently [8<\/a>]. Ruby laser type is not a good choice for people with tanned skin, pale skin, or dark-toned skin, as it might cause hyperpigmentation. It has a built-in cooling-off feature to keep the skin under treatment cool, making it a pain-free procedure than other laser types.<\/p>\n

Type 3: Nd: YAG Laser for Hair Removal<\/h3>\n

This type of laser is one of the renowned hair removal procedures that utilize dual frequency mode with a stunning wavelength maintained at 1064 nm along with a green laser light featuring a wavelength of 532 nm [9<\/a>]. Whether you have dark African skin or pale Asian skin, Nd: YAG laser hair removal type is very effective [10<\/a>]. This hair removal process has a swift repetition rate and is useful for removing unsightly hair from large skin areas. This laser works by heating your tissue’s pigmented part called chromophores and doesn\u2019t affect the surrounding tissues [11<\/a>]. The high-precision laser beam targets the follicle to cut down regeneration.<\/p>\n

Type 4: Diode Laser for Hair Removal<\/h3>\n

This type of hair removal relies on using semiconductors or diodes that work with a wavelength range between 800 and 810 nm. The laser’s longer wavelength allows it to penetrate deeply into the skin and is perfect for treating large skin areas. The diode laser hair removal procedure is pain-free and needs just a few sessions to flaunt a hairless look. Right from the first session of diode laser therapy, you might observe about 20 to 25% of hair reduction.<\/p>\n

Type 5: Alexandrite Laser for Hair Removal<\/h3>\n

Also known as the red light laser, the Alexandrite laser utilizes an infrared beam with a red spectrum having a wavelength measuring 755 nm [12<\/a>]. The laser process is based on converting light with high energy into heat to target the treatment area. It also employs a photothermolysis process to induce tissue damage without causing harm to surrounding cell structures [13<\/a>]. Developed during the 1990s, this laser type is considered to have an edge over the rest, as it has deep penetration ability and uproots the hair follicles from their roots. This laser type causes less discomfort or irritation than diode laser and is a perfect choice for permanent hair removal. The Alexandrite laser type is useful for removing hair on your bikini area<\/a>, upper lip<\/a><\/strong>, back, and leg [14<\/a>].<\/p>\n

How Different Lasers Suit Different Hair and Skin Types<\/h2>\n

Laser hair removal technology has evolved quickly to help you achieve visibly smooth and hair-free skin within a short time. But, you must also understand that not all hair types and skin tones are the same, and their distinct traits can influence the choice of your laser treatments [15<\/a>]. It is essential to understand the relationship between the hair and skin types and variants in laser procedures to make a well-informed decision for a better outcome.<\/p>\n

Fitzpatrick scale<\/h2>\n

The Fitzpatrick scale [16<\/a>] is considered a significant tool in the arena of laser hair removal, as it offers a clear-cut idea of how a specific skin tone will respond to a particular laser type. According to this scale, skin types I and II contain low melanin levels, and skin types III and IV contain high melanin content. Based on this scale, dermatologists determine the right kind of laser treatment with appropriate energy settings to provide you with the best and safest outcome [17<\/a>]. The following are the skin types categorized by the Fitzpatrick scale.<\/p>\n
