How to Use an At-Home Laser Hair Removal Machine

by Véronique Raymond

A laser hair removal machine works by repeatedly emitting a zap of light that heats the hair pigments to damage the hair follicles and cause the hair to fall out. The damage of the hair follicle removes the current body hair and prevents the hair from growing back quickly. This means that you have smooth skin for longer periods of time in between treatments, whereas shaving, waxing, and plucking require frequent touch-ups to keep the skin smooth. 

There are two methods of laser hair removal treatment. There is intense pulsed light hair removal and radiofrequency hair removal. Both methods use laser treatments to zap body hair to damage the hair follicle and prevent it from growing back quickly.


IPL Hair Removal

IPL hair removal is what most at-home laser hair removal systems use for hair reduction. IPL lasers, also known as intense pulsed light, emit a pulse of light in broad wavelengths that are absorbed into the pigment of the hair. The pigment, also called melanin, absorbs the light heat and damages the hair follicles. This causes the hair to fall out and slow down the time that it takes new hair to grow.

Many IPL hair removal devices have built-in skin sensors that will test the sensitivity of your skin, as well as your skin tones and hair color, to determine what level of intensity the laser hair removal machine should use. This makes an IPL hair removal device perfect for home use.


Radio Frequency Lasers

When radiofrequency lasers are used to remove body hair, a diode laser emits a beam of light that creates a precise pulse of energy that is directly absorbed by the melanin in the hair. Like an IPL hair removal device, this causes the hair follicle to become damaged, making the hair fall out and preventing new hair from growing back quickly.

The radiofrequency laser is so precise that it doesn’t damage the skin surrounding the hair. This keeps your skin safe during both at-home laser hair removal and during professional laser hair removal.


How to Use an At-Home Laser Hair Removal Machine

At-home laser hair removal machines are easy to use but only if you know how to use them. It’s important to learn how laser hair removal machines work and how you should treat the skin before and after treatment. This will help you get the best results and keep the best results when using a laser hair removal machine.


Preparing the Skin Before Laser Hair Removal

It’s important to prepare your skin before you perform any type of skincare or laser hair removal treatment. To do this, you should shave the area you are going to be treating. Shaving the treatment area removes the hair above the surface of the skin while leaving the hair follicle in place. This prevents any surface hair from burning during the laser hair removal process.

You should also avoid any sun exposure before your laser hair removal treatment procedure. Sun exposure can change the pigmentation of the skin and hair, making it difficult for the laser to pinpoint where the hair follicle is. This is why dark skin and light hair colors are sometimes less affected by laser hair removal machines. The laser needs to see the contrast in color between the hair color and skin color.

Don’t pluck or wax any body hair that you want to treat with a laser hair removal machine. Plucking or waxing removes the hair follicle which is needed in performing successful permanent hair removal, so it’s vital that you keep the hair follicle in place before laser hair removal treatment. If you have plucked or waxed your hair, make sure you wait at least four weeks before you use a laser hair removal machine.


How Home Laser Hair Removal Devices Work

Once the area of the body has been treated and prepared for laser hair removal, it’s time to use the home laser hair removal device. Some devices are battery-powered while others have a power cord and require a power supply to work. If the at-home laser hair removal device you have is battery-powered, you’ll need to make sure it is fully charged so that it works properly.

You will either have to manually control the energy levels of the machine or the energy levels will be automatically adjusted by the machine. If you manually have to choose which energy level you want to choose, make sure you know what the energy level should be for the area of the body that you are treating.

The laser hair removal machine emits a number of pulses when in use. You will hold the device to the area of the skin that you’ll be treating and let the laser heat the hair follicle so that the hair falls out prevents future hair growth.

You should always focus on small areas of the body when using an at-home laser hair removal device. The best areas to focus on are the underarms (armpits), bikini line, and legs.

Home laser hair devices work best on dark hair and light skin types. The wavelengths from the laser hair removal machine need to be able to detect the hair color on the skin which is why dark hair works best.

Darker skin types are less affected by the wavelengths from a laser hair removal machine because the skin tone blends in with the dark hair color, making it difficult for the laser to determine where the pigmentation is within the hair follicle.


What Are the Side Effects of Using a Laser Hair Removal Machine?

Laser hair removal machines are safe to use at home. There is very little risk of any type of significant injury to the body or skin when using the laser hair removal machine correctly.

The most common side effect of using a laser hair removal machine is red, swollen, and irritated skin. This usually only lasts for a few hours after treatment, but if it continues to persist, you can see a dermatologist to get a topical cream to apply to the area to provide relief.

If you plan to use a laser hair removal machine on your face, such as your upper lip or chin, you should use protective eyewear to keep your eyes protected during treatment.


The Best Home Laser Hair Removal Devices

There are three at-home laser hair removal devices that we want to include in this list. They are the Tria Beauty Laser Hair Remover, the Braun Silk Expert Pro 5, and the Silk’n Infinity laser hair removal device.

1. Tria Beauty Laser Hair Remover

Tria Beauty Hair Removal Laser

The Tria Beauty Laser Hair Remover is an IPL laser that works best on lighter skin tones and dark hair. It has a built-in skin sensor that will unlock the Tria laser only if your skin tone is safe for laser use.

It has five different laser settings that you can choose from when using the device. It has 90,000 total pulses and will fully recharge 300 times. Because it has an internal battery, it’s fully rechargeable and allows you to take it on the go anywhere you need.

To use the Tria Beauty Laser Hair Remover, make sure that it is fully charged. Then, power the unit on and apply the laser to the area of the body you want to treat. Only use the number of light pulses that are recommended for the area of the body you’re treating.

The Tria Beauty Laser Hair Removal is FDA-approved for safe and effective use.


2. Braun Silk Expert Pro 5

Braun IPL Hair

The Braun Silk Expert Pro 5 has 400,000 light pulses that should last for up to 22 years. It is built with the Braun SensoAdapt technology that will test your skin and automatically adapt the light intensity used to perform the laser hair removal treatment.

You can use the Braun Silk Expert Pro 5 on your legs, underarms, chin, upper lip, and bikini area. Because of the SensoAdapt technology, you shouldn’t have to perform a patch test before use. Just make sure to focus on smaller areas first to make sure your skin and hair will respond well to the device.


3. Silk’n Infinity

Silk’n Infinity

The Silk’n Infinity laser hair removal device has an unlimited number of flashes so you’ll never have to replace or refill the device. It has a built-in fail-safe sensor that will test your hair and skin to determine which laser energy level it needs to choose.

The Silk’n Infinity laser hair removal device requires a power supply in order for the device to be used. Once it is powered on, you will apply the laser to the area of the body you want to treat. The unit will choose which energy level to use based on your hair and skin color.


Laser hair removal machines are easy to use as long as you know how they work and how to prepare your skin before you use them. Most at-home laser hair removal machines will permanently remove hair after 8 treatments, but you may need to perform touch-ups on certain areas of the body to keep them smooth and hair-free.
