If you have never had laser hair removal before and are considering getting the treatment, here’s everything you need to know beforehand! 

How Does Laser Work for Hair Removal?

The laser emits a beam of light which passes through the top layers of the skin and targets and destroys the hair follicle. The laser light is absorbed by the pigment or colour in the shaft of the hair and follicle. The energy from the laser heats and permanently destroys the stem holding the hair.  This loosens the hair which will eventually fall out. New hair cells are also prevented from forming.

Should I go to a clinic for laser hair removal or buy a device online? 

Whilst there are now laser hair removal devices you can use at home available to buy in cosmetic shops or online, lasers used in clinics are far more powerful and effective. These devices typically start from £100, but the expertise, results and tailored plans that you get in a clinic are unmatched. 

What is the Best Laser Treatment?

Laser for laser hair removal can be divided into 5 types as there is no ???one type suits all.’ We administer a range of laser types in order to have an effective treatment for everyone’s skin type. There’s often confusion around types and brand names that make claims to be better than each other, however this is generally not the case – it’s more to do with your skin and what works best for you.

Wavelengths tell you how deep it goes into the skin. The higher the number, the deeper It goes. Nd: YAG has the highest number (1064nm) so it goes the deepest. This is important if you have dark skin, as you want the laser to go deeper, so it doesn’t change your skin colour on top by not going deep enough.

IPL wouldn’t typically be called a laser but has more features like a flashlight which does not penetrate deep into the skin. It shines light over a wide area, affecting the surrounding skin. It should not be used if you have darker skin as it can affect your skin’s pigmentation. Hair removal takes longer with this treatment as it is less effective.

After your session, the treated area is quite sensitive and can appear red for a few hours afterwards

Does laser hair removal get less painful after each treatment?

Like most things, you should get used to the laser hair removal sensation and tolerate it better the more sessions you have. If the pain is more unbearable your practitioner can apply numbing cream over the treated area.

This will be applied, and you have to wait up to 30 minutes for it to take effect. If you are on your period, it can make your skin more sensitive to the laser so it may hurt more during this time.

As the laser transfers a lot of heat energy into the skin, you should avoid anything that heats up the skin further like saunas and exercise for at least 48 hours following your laser session. This will allow your skin to continue with the healing process without interruption.

Will six sessions of laser hair removal be enough?

Depending on how well you respond to the laser treatment and the area treated, will determine how many sessions you will need.

Other clients with darker skin tones and thick coarser hair will probably need more than 6 sessions sometimes over 10.

Can I be exposed to the sun after laser hair removal?

You should cover up the area as much as possible to avoid. This is easier if you have had , but harder if your arms or face have been lasered.
