Unwanted hair from the skin is removed using a medical procedure known as laser hair removal, also referred to as laser therapy or laser treatment. Lasers use light energy to break down the cells of the target hairs, killing them. As a result, bald patches will vanish and hair will start to thin. It will be replaced by a new growth of hair.
Today’s market is home to a variety of lasers, each with distinctive features and functionalities. It’s crucial to pick a laser that satisfies your unique requirements for safety and effectiveness.
How does laser hair removal work?
The fundamental idea behind all types of laser therapy is straightforward: when energy interacts with molecules in our bodies, it causes biological harm. This causes visible heat and destruction when it occurs inside living tissue such as skin or hair follicles (or feel).
Lasers produce brief bursts of concentrated energy known as photofrinuclei, which interact biochemically with photosensitizers already present in the human epidermis to cause thermal damage that ultimately results in pangenesis (the formation of new dermal papillae).
A strong light beam is used in laser hair removal to harm the hair follicle. By doing so, the root is destroyed, halting further growth. The skin covering the destroyed follicle is then removed with the laser.
Your skin type and the number of hairs on your body are just two of the variables that affect how long it will take for laser hair removal to take effect. Depending on how dark your pigment is and how thick your hair is, the average treatment time per area is six weeks.
Various kinds of lasers are employed for laser hair removal:
The three most common types of lasers used for laser hair removal are CO2, YAG, and IPL.
The way YAG lasers work is by heating up the hair follicle with a brief burst of light. Because it is extremely gentle and effective on the majority of skin types, this is frequently the first type of laser used to remove unwanted facial hair.
IPL damages the dermal top layer of cells by emitting brief bursts of infrared light (the deepest layer beneath the surface skin). This destroys the melanin and the hair follicles, which over time causes a gradual but steady loss of hair.
Cold gas emissions from CO2 lasers are directed at tiny blood vessels near scalp hairs, causing them to burst and die. These procedures don’t need any downtime or additional preparation prior to the process, unlike other types of lasers (although some patients may experience minor redness or swelling).
- Alexandrite Lasers
By combining infrared and visible light, Alexandrite Lasers instantly kill skin cells by destroying them inside the hair follicle. They are therefore perfect for those who want little recovery time after treatment or have sensitive skin.
Duration of treatment and areas subjected to laser hair removal
There are numerous laser hair removal procedures that each have their own advantages and disadvantages. The length of the hair treatment will vary depending on the type of laser being used, but most procedures last fifteen minutes or less.
Legs, upper back, and the face are frequently treated body parts. Individual treatment sessions can sometimes be more effective for some people than Full Body treatments, but this isn’t always the case.
The best type of laser therapy for you will depend on your skin tone and other factors, so discuss this with your doctor!
