The Science (And Process) Behind Laser Hair Removal

Laser hair removal has been around for years, but that doesn’t mean that we are all familiar with the process. It is commonly known that laser hair removal is one method of removing unwanted hair in areas all over the body. You can also use laser skin rejuvenation along with it to get that younger and vibrant looking skin. Let’s take a look at what that really means.

The Process

You can start your journey to laser hair removal with a consultation with a professional from This is important so the physician will have a chance to review the type of hair and skin that you have to know which type of laser is appropriate and how many treatments might be required.

Laser hair removal works using cutera lasers that direct concentrated laser light onto your hair’s follicle. The light is converted to heat within the hair. It stops the hair’s ability to grow by damaging the follicle itself. This will not harm your skin. The light from the laser is attracted to the pigment within your hair so it hones in directly to the follicle. It uses a wide beam so that more than one follicle can be treated at the same time.

The Number of Treatments

The number of treatments that you require to get the right results will vary from person to person, but it is likely that you will need several treatments to get the results you want. When you go in, your hairs will be at various growth cycles, making some follicles more receptive to the laser light than others will be.

Your hair follicles are most responsive at the initial growth stage, known as anagen. This means the hair is actively growing and contains melanin, which attracts the laser. The more melanin that your hair has, the more light will be concentrated into the follicles, and the better results that you will get.

Treatments need to be spaced out by 4 to 6 weeks to help catch the hair follicles at different cycles. Some people can require as many as 10 treatments, but it really depends on the area that is being treated and the type of hair that you have.

Before Treatment

Before having your laser hair removal treatment, you will need to shave the area about 12 hours ahead of time. You should also not have any tanning products on your skin. When you shower, use an exfoliating scrub to remove any dead skin build up. Likewise, do not have any chemical peels performed in the area and you should avoid sun exposure for the area that is going to be treated for at least 2 weeks prior to your first treatment date.

All of these recommendations will help ensure that you have a successful treatment process and that your results will be what you were hoping to achieve.

After Treatment

Following the procedure, you might notice that you are heat sensitive in the treated areas. You might have a little bit of redness as well. Your physician might give you or recommend an ointment to apply to the skin to help with the redness and the healing process.

You should not go into the direct sunlight after a laser hair treatment either as your skin is more susceptible to damage or burning. When you do go out, you should be using SPF 50 to keep your skin as protected as possible.

You will also need to avoid shaving or waxing in the treated area for at least 24 to 48 hours after treatment. Your skin needs a break and waxing and shaving will only irritated it and extend the amount of time needed to heal properly.
