A 810nm diode laser, sometimes referred to as an 808nm diode laser is a type of laser that is commonly used for laser hair removal. It produces a wavelength of 810 nanometres (nm), which is absorbed well by the pigment (melanin) in hair. The laser energy is absorbed by the pigment in the hair shaft and follicle, which damages the hair-producing cells and prevents the hair from growing back. Laser hair removal with an 810 nm diode laser is generally safe and effective, and can be used to remove hair from almost any part of the body. It is a popular choice for hair removal because it can treat a large area in a relatively short amount of time and produces good results with minimal discomfort. A diode laser for hair removal comes in many other wavelengths such as 755nm Alexandrite and 1064nm Yag. These are both good wavelengths for a specific target and will be discussed in another article.
- Wavelength: The wavelength of a laser refers to the distance between successive peaks of the laser’s electromagnetic wave. The 810 nm wavelength is absorbed well by the pigment (melanin) in hair and is effective for targeting and destroying the hair-producing cells.
- Fluence: Fluence is a measure of the energy density of a laser beam. It is typically measured in joules per square centimetre (J/cm^2). The fluence of a laser beam determines the amount of energy that is delivered to the tissue being treated and can affect the effectiveness of the treatment.
- Pulse duration: The pulse duration of a laser refers to the amount of time that the laser is emitting energy during each pulse. A longer pulse duration may deliver more energy to the tissue, but it may also increase the risk of side effects such as skin irritation.
- Spot size: The spot size of a laser refers to the size of the area being treated with each pulse of the laser. A larger spot size may be able to treat a larger area in a shorter amount of time, but it may also increase the risk of side effects.
- Repetition rate: The repetition rate of a laser refers to the number of pulses per second that the laser delivers. A higher repetition rate may be able to treat a larger area in a shorter amount of time, but it may also increase the risk of side effects.
HOW DOES 810 DIODE LASER WORK
During a laser hair removal treatment with an 810 nm diode laser, a beam of laser light is directed at the area of the skin being treated. The laser energy is absorbed by the pigment (melanin) in the hair shaft and follicle, which damages the hair-producing cells and prevents the hair from growing back.
The 810 nm wavelength is absorbed well by the pigment in the hair, which makes it effective for targeting and destroying the hair-producing cells. The laser energy is delivered in short pulses, which allows the laser to heat up the hair follicles without damaging the surrounding skin.
Laser hair removal with an 810 nm diode laser is generally safe and effective, although some people may experience side effects such as redness, swelling, and skin irritation after treatment. These side effects are usually temporary and resolve on their own within a few days.
Overall, the 810 nm diode laser is a popular choice for laser hair removal because it can effectively remove unwanted hair with minimal discomfort and produce long-lasting results.
HOW MANY TREATMENTS WOULD YOU NEED FOR A LASER HAIR REMOVAL
The number of laser hair removal treatments needed can vary depending on several factors, including the area being treated, the density and thickness of the hair, and the individual’s hair growth cycle.
On average, most people will need between 3 and 7 laser hair removal treatments to achieve optimal results. However, some people may need more treatments, while others may require fewer treatments.
It is important to note that laser hair removal works by damaging the hair-producing cells, which can take time to show results. It is normal for treated hair to continue growing for several weeks after a laser hair removal treatment, as the damaged hair takes time to be shed from the skin.
It is also important to follow the recommended treatment schedule provided by your healthcare provider to ensure that the treatments are spaced appropriately and to maximise the effectiveness of the laser hair removal.
The aftercare for diode laser hair removal is generally straightforward and simple. Here are some general guidelines for aftercare:
- Avoid exposure to the sun: After treatment, it is important to avoid exposing the treated area to the sun for at least a week. If you must be in the sun, be sure to apply a broad-spectrum sunscreen with an SPF of 30 or higher.
- Avoid hot water: Avoid hot showers, hot tubs, and saunas for at least a day after treatment.
- Avoid physical activity: It is best to avoid strenuous physical activity for at least a day after treatment, as this can cause sweating which may irritate the treated area.
- Avoid certain products: Avoid using any products that contain alcohol, fragrances, or other irritants on the treated area for at least a day after treatment.
- Use cold compresses: If the treated area is painful or swollen, you can apply a cold compress to help reduce discomfort.
- Avoid picking at scabs or blisters: If any scabs or blisters form on the treated area, it is important to avoid picking at them. Let them heal naturally to avoid scarring.
It is also important to follow any specific aftercare instructions provided by a qualified provider.
