How does laser work?

Lasers used in clinics are far more powerful then the home laser devices you may have seen online costing around a hundred pounds.

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.

What is the best laser?

Without baffling you with laser science, Laser for laser hair removal can be divided into 5 types. It would be nice if there was one laser that worked for everyone, Sadly this is not the case. A lot of clinic websites mentions different brand names all claiming to be the best, this  causes even more confusion!.

Here are the main things to takeaway.

IPL is not considered a laser, more 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. Also, hair removal takes longer as it is less effective.

  • ND: YAG LASER

Best for dark skin.

The Nd: YAG Laser is preferred for hair removal for dark skin. It is safer and its long wavelengths (1064nm) go deeper into the skin.

Popular brands: Candela Gentlemax Pro, Cutera CoolGlide, Cynosure Elite

  • ALEXANDRITE LASER

Best for olive skin.

Operates on the wavelength of 755nm although not as long as the Nd:YAG is suitable on a wide range of skin tones. Also has a larger spot size and repetition rate so is one of the quickest treatments available.

Popular brands: Candela Gentlemax Pro, EpiTouch Plus, Cynosure Apogee

  • DIODE LASER

Best for fair and medium-dark skin

The Diode operates on the 800nm wavelength and is designed for fair to medium-dark skin types. It is still fairly new so there is not proven like Alexandrite and ND:YAG.

Popular brands: SLP 1000, LaserLite,  LightSheer, ALma SopranoXL (also known as SHR, or Super Hair Removal)

  • RUBY LASER

Best for very fair skin

This is the oldest type of hair-removal laser. It operates on the 694nm wavelength so is suitable or very light skin and light hair removal.

Common brand names: Palomar E2000, RubyStar

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.

DOES IT HURT?

Compared to other forms of hair removal like waxing or epilation most people would say laser hair removal is uncomfortable and not painful.

People experience pain differently and some areas of the body are more sensitive than others. Some people won’t notice a thing, others will feel a warming of the area. When asked to compare it something people have often compared it to being flicked with an elastic band.

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 you this can make your skin more sensitive to the laser so it may hurt more during this time.

HOW MANY SESSIONS DO i NEED BEFORE my HAIR DOESN’T GROW BACK AT ALL?

Laser hair removal works best when a course of treatments are performed at regular intervals. This should give you the best results. Most clinics recommend a course of treatments.

This is commonly between 6-8 sessions. Depending on how well you respond to the laser this may be more than enough or you may need to extra top up sessions to get the results you are after.

Can I have a sauna after laser hair removal or exercise?

As the laser transfers a lot of heat energy into 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.

We have treated oriental clients who experience amazing results after just 4 sessions. Other clients with darker skin tones and thick coarser hair will probably need more than 6 sessions sometimes over 10. Hormones also play a part which differs from person to person.

Sun exposure after laser hair removal?

You should cover up the area as much as possible to avoid sun exposure after your laser hair treatment. This is easier if you have had bikini line laser, but harder if your arms or face have been lasered.

The first 48 hours after laser treatment are important to protect your skin and avoid sunlight. Use a high factor sun cream with an SPF of 30+ and cover up. In the weeks following your treatment, continue to wear SPF and protect your skin by covering up as much as possible.

WHERE CAN YOU NOT HAVE LASER HAIR REMOVAL?

We receive a lot of requests to perform laser on eyebrows which cannot be done due to the dangers and risk involved of using lasers so close to the eyes.

CAN I HAVE LASER OVER MY TATTOO?

No. you can have laser around the tattoo but not over it. The laser will be attracted to the colour pigment in the ink causing pigmentation issue to the skin. An experienced technician can skilfully go around your tattoo.

If you are thinking about getting a tattoo and want to be hair free, get laser hair removal done first.

HOW LONG DO YOU WAIT BETWEEN SESSIONS?

Your sessions are usually spaced about 6 weeks apart. This is so your sessions are timed with your hair growth cycle that takes about 6 weeks

That is why you will be advised not to wax or epilate in between session as it will cause disruption to your hair growth cycle.

Shaving is fine as it cuts the hair above the epidermis or top layer whereas waxing and epilating remove hair from below.

What if I miss a session what should I do?

It’s normal that life will get in the way sometimes. For best results you should try and stick to your appointments as consistency is the key to great results. As mentioned, if you are away and miss an appointment shaving is the only method you should consider. Shaving will cause the least impact on your treatment than the other methods of hair removal.

HOW LONG laser hair removal LAST?

Results will vary from person to person. Hormonal changes can affect your hair growth too. You can experience up to 90% permanent hair reduction after you have completed all your treatments.

The occasional top up session may be required yearly. For most, the results have a huge impact on their lives.

HOW MUCH DOES IT COST?

With most laser hair clinics pricing is structured to encourage you to buy packages. Clinics offering pay as you go prices will not give you the best results, unless you have previously completed laser and are buying a single pay as you go top up.

This is because laser hair removal requires consistency. Randomly buying pay as you go treatments is a bad idea. For the laser to work you need multiple sessions spread evenly apart. Laser won’t work without consistency.

Full body laser hair removal costs anywhere between £2000-£3500. Premier Laser price match so have some of the lowest prices in the industry. Expect to pay £3500 on Harley Street.

With finance options starting from £280 your monthly repayments can be as low as £22.

ON AVERAGE, HOW MANY SESSIONS DO YOU NEED FOR THE BIKINI AREA or UNDERARMS?

These smaller areas respond well to laser hair removal. For best results, we recommend purchasing a package of  8 sessions.

I HAVE VERY FINE extremely BLONDE HAIRS – WILL LASER WORK FOR ME?

Best results are usually experienced by people with darker hairs such as brown and black. Very light blonde hair does not contain enough pigment for the laser to work.

laser hair removal

Does laser work on red or ginger or grey hair?

The laser will not work on grey hair as it requires pigment. Although lasers have advanced recently making it possible to treat red and ginger hair for the majority of red and ginger haired people it is unlikely laser will work on you.

IS LASER SUITABLE WITH PCOS?

If you have Polycystic Ovary Syndrome (PCOS) and want to have laser removal treatment you can achieve fantastic results with laser hair removal. Results are not guaranteed though as PCOS affects the body’s hair growth so continuous laser session may be required to stay on top of the hair growth.

It is important to do your research and have realistic expectations if you have Polycystic Ovary Syndrome so you are not disappointed with the outcomes. Be careful of any clinics over-promising on results. Look for a clinic that will work with you, you feel comfortable with and will set up a treatment plan where you work and communicate closely together to achieve your goals.

It is not all doom and gloom though. We have seen clients experience life changing results which impacts their self confidence and quality of life with laser hair removal.
