Dual Radio Frequency - SkinFirst

Dual Radio Frequency

Before explaining the benefits of our technology, we should first give some background information of the biology and physics surrounding the whole concept of skin rejuvenation and hair removal using light and electrical heat.

The human skin and its associated conditions, many as a result of the ageing process and/or exposure to UV light (which our equipment filters out of course!) can be illustrated as follows:


There are 4 main targets in the epidermis (skin surface) and dermal (lower) areas that we wish to isolate in order to treat varying conditions, or to improve the appearance of our skin. These are:

  • Haemoglobin in vessels
  • Melanin in hair and pigmented lesions
  • Collagen Fibres
  • Elastin Fibres and Fat

These targets are reached and treated (either denatured as is the case with collagen when achieving skin rejuvenation; or destroyed as in the case of melanin when performing hair removal), via a process known as Selective Photothermolysis.


Photothermolysis was originally undertaken using Lasers (Laser being an acronym for Light Amplification by the Stimulated Emission of Radiation).

Lasers have been used successfully and with great success in medicine for the past 30 years. However, advancements in physics have resulted in a variation of the technology now being used for many treatments, known as Intense Pulsed Light (IPL). Whereas lasers emit a single narrow wavelength of light, IPL delivers hundreds of wavelengths of light. These varying wavelengths are selectively absorbed by different target cells in the skin, allowing many skin conditions to be treated with IPL technology as opposed to a more restricted treatment afforded by the narrow wavelength of a laser.

The difference between the concept of a laser beam and IPL light is shown below:


The absorption spectrum of IPL is narrowed to the wavelengths indicated below, thus cutting out the more harmful wavelengths in the spectrum including UV light.


Our advanced skin system works on the basis of the combined technology (emitted simultaneously) of MPL® (the latest generation of IPL) and Radio Frequency, and is referred to as electro-optical technology. Only a very small percentage of clinics in the UK have this advanced technology which is more extensively used in countries which are ahead of us in the area of aesthetic development, including the USA, Israel (where much of the R&D is concentrated), Spain, Italy, Canada, and the Far East. SkinFirst have been pioneering electro-optical technology in the UK for over 5 years, and own the registered trademark of MPL® for Multi-Pulsed Light.

Electro-optical technology
Our skin system, which simultaneously delivers Multi Pulsed Light (MPL®) and bi-polar radio frequency, achieves outstanding results.

Electro-optical technology is the safest technology of this type on the market and is therefore more suitable for darker skins, which have a higher concentration of melanin (and hence a higher propensity towards hypo-pigmentation). It also achieves better results on lighter haired individuals (in hair removal mode) as it requires less melanin absorption to produce results.

How does combined electro-optical energy work?
The technology not only uses MPL® (advanced IPL) light energy to target cells in the skin for treatment (such as blood vessels for the removal of thread veins, or melanin for the removal of age spots) based on the principle described above of Photothermolysis; but it also uses a safe radio frequency wavelength to emit heat from within. Because the radio frequency does not heat the epidermis (surface area) of the skin, but penetrates deeper down within the dermis, following the path of least resistance created by the MPL®, the same or better treatment outcomes can be achieved using a lower energy of light emission. This can be illustrated as follows:


Because we are able to use a lower energy of MPL® to achieve the desired results (due to the fact that the RF energy is assisting the overall treatment), there is less likelihood that the melanin which is in the skin surface will be overly heated (because MPL® energy heats down from the epidermis whereas RF energy heats electrically from within). This makes it more suitable and safer for darker skinned individuals than traditional IPL systems alone; it also renders the possibility of removing lighter hairs greater. This is because there is less dependence on targeting the melanin in hair to destroy the hair follicle, as the radio frequency simultaneously heats the hair bulge to attack the hair on 2 fronts without raising the temperature of the epidermis. Not easy to follow in website text; so we have illustrated below how the technology would work in relation to hair removal and skin rejuvenation, which are two of our most popular treatments:

Hair removal
The basic anatomy of hair is illustrated below:


Hair has 3 distinct phases in the growth cycle, and it is only when individual hairs are in the active growing phase that they can be destroyed. Therefore at any point in time, not all hairs will be destroyed. Furthermore, new hairs can grow in addition to those that will subsequently enter an active growing phase. This is why a number of treatments are required for hair removal (depending on skin and hair type and area of the body/face being targeted).


As you can see from the diagram above, the melanin in the hair attracts the optical energy from the MPL® and that destroys the follicle. Because dark hair contains more melanin it is usually easier to treat. However, this holds most for those with fair skin and dark hair, as fair skin has little melanin in the epidermis (pigment) and the dark hair has plenty in the hair shaft, so the combination of being able to put in light energy to destroy the hair without changing the pigment in the skin is ideal. With darker skinned individuals, although there is plenty of melanin in the hair to target, because there is also a high amount of melanin in the skin pigment we have to be careful not to cause hypo-pigmentation (lightening of the skin). This is why many clinics cannot treat dark skinned individuals for hair removal and have to use a more powerful, painful and less safe laser, or not offer this treatment for darker skinned clients. Our combined technology, however, enables us to reduce the MPL® energy on the skin surface (so skin pigment is unaffected by the treatment) and still successfully remove the hairs, as we are simultaneously applying a radio frequency heat to the hair root, which helps to destroy the hair without harming the surrounding structure. This is effective, safe and more comfortable. However, as with all of our treatments we always do a patch test first to ensure that there will be no adverse pigmentary reaction.

Skin Rejuvenation
The synergistic effect of using MPL® and RF has 3 benefits for skin rejuvenation:

  • Removal of vascular/pigmented blemishes
  • The stimulation of mediators/fibroblasts leading to collagen remodelling
  • The direct stimulation of collagen leading to some immediate tightening


Our technology is particularly safe, because not only does it filter out harmful wavelengths in the outer regions of the light spectrum, but it also permits (via the use of a combined and controlled bi-polar radio frequency emission) the lowering of the light energy required, to achieve desired outcomes on the skin, to improve its elasticity and youthfulness, in addition to eradicating unwanted conditions.

As radio frequency is not absorbed selectively by melanin, there is the additional benefit that the system has the ability to treat targets with lower optical absorption such as lighter hair.

Additional benefits
Aside from the main benefit that our skin system can be used on dark skin and lighter hair, it can reach to greater depths than traditional IPL systems due to the directional RF component, which means that we can offer deeper and more effective treatments. It is also more comfortable on the skin surface, because of the lower IPL energy needed here. This is further enhanced by our impressive inbuilt cooling system which operates on the skin simultaneously with the heat application.

Dual Radio Frequency is our most popular treatment. It is a heat based treatment, comfortable, relaxing and effective, in treating for lines, wrinkles, slack skin, and rejuvenation.

“The Ultimate Dual RF really is the Ultimate in safe, effective Radio Frequency Skin Tightening”

The facial treatments target nasal labial folds, lines and wrinkles around the eyes, slack jaw line, neck creases, and mouth, In addition body treatments can be performed using the monopolar treatment tips which can range the lower dermis and fat cells.

Radio frequency is one of the safest, least invasive and yet most effective non-invasive treatment available to people of all skin colours, for rejuvenating, lifting and tightening skin. It is a treatment that is loved by men and women aged 40 and over, but is also very popular with younger clients who want to glow and look their best for a night out. It can be performed as a one of treatment, or more popularly as a course of typically 6 to 10 treatments (depending on age and skin laxity) followed by ongoing maintenance treatments as required.

In our early 20’s we have plenty of collagen in our skin. However, with age our collagen production decreases, so that by the time we reach our mid 40’s it is barely in production and due to the lack of collagen we notice our skin loses elasticity, sags and forms lines and wrinkles. Using the very latest SkinFirst Radio Frequency equipment we can stimulate your own natural collagen and tighten your elastin fibres to bring about long-lasting rejuvenation, lifting, firming and a smoothness and freshness you may not have previously experienced.

You can see in the relevant section under ‘Our Treatments’ how the Radio Frequency is applied and how it works.

Clients are often sceptical about the results that can be expected from such an enjoyable treatment but are very often astounded at the benefits and noticeable difference. Technology has advanced such that genuine and visible results are readily and affordably available with no down-time and great comfort. Why don’t you come in and try this treatment for yourself, as we would love to help you to look and feel years younger.

Client Testimonials

Fantastic service as always. Izzy & Millie make you feel so welcome. Izzy is super efficient & professional. I highly recommend Skin First.


I wish I could go for a treatment here every day, it was such a lovely experience! Hayley was wonderful, so informative and just magical at what she does! everything was fantastic from the music to the decor to the energy of the space. Can’t wait to book in again soon! I’ve never had a facial before as I felt intimidated by such environments but it was such a warm and friendly place to be, I’d highly recommend this clinic to anyone and everyone!


Izzy was brilliant, makes you feel really relaxed and takes time to make sure you are comfortable throughout the treatment. Had 3 RF Micro needling sessions and love the results.


I have very dark hair and have always been very conscious of it. I started to have the laser hair removal treatment firstly to my underarms. After only two sessions I was so impressed with the results. My hair was virtually gone! As a result I now have three areas treated. It is truly a fantastic treatment and leaves your skin not only hair free but baby smooth. Furthermore, the service you will receive is both informative and highly professional. After years of waxing and sugaring I have now found a hair removal treatment that I would whole heartedly recommend.

I have always had my underarms waxed but decided to try laser hair removal instead. After only one treatment I was surprised at how few hairs grew back. I have just completed my fourth treatment and can’t really see any remaining hairs. But i will finish my course of 6 to ensure that all hairs have been removed as my therapist (Cathy) told me that there are some hairs that may not be in the active growing phase which could still come through. I am delighted with the results and will definitely keep my standing order going until I have done my bikini line and then maybe even my legs.

I have always had poor skin tone and a red blotchy face, which was diagnosed as Rosacea 3 years ago. I have been prescribed antibiotics orally and taken topical medication which helped a little with the postules but did not really have significantly noticeable results; and I don’t like to take antibiotics longer term. I was therefore delighted to find that the light based treatment at SkinFirst was able to help my condition. My cheeks are much less flushed and my nose has improved markedly, and that is only at the half way stage of my full course. I would recommend this treatment to anyone else who has rosacea.

My treatment at SkinFirst, at The Village in Warrington, was quick, easy and I was very happy with the result. I had an unsightly cluster of small red veins on my face and they have now gone completely.

I would like to thank you for the improvements to my general skin condition. Many people have commented about how well I am looking and I feel like I look several years younger at least. It has given me a boost of confidence, and I think I am going to tackle my thread veins next.

I was amazed that the sun spots on my hands disappeared following a course of treatments by SkinFirst. I expected them to perhaps go a little lighter but not to go completely. There was the added benefit that my skin felt much softer too. My hands were a give away to my age and I now feel so much happier about showing them off!

As a Clinical Scientist, I recently carried out training with the staff of SkinFirst at Warrington and was most impressed with the new ‘Super MPL Combi’ machine they have installed. This new technology uses a combination of Intense Pulsed Light and Radiofrequency making the treatments effective at lower levels of energy than would normally be the case. This makes the treatments safer and more comfortable for the clients.

I am extremely pleased with the outcome of the treatment I recently received at SkinFirst in Warrington. I had a prominent blood vessel on the side of my nose which has now completely gone. I hardly felt anything during the treatment which only took a few moments. This bothersome blood vessel had been previously treated at another clinic using a different type of laser which was not only painful but did not completely remove the problem – it came back. I would certainly recommend SkinFirst for anyone with a similar problem.

I have only compliments to say, having had beauty treatments for many years Skinfirst has to be the most professional, confident, competent and comfortable to date. I wish you and you company every success and I will certainly be recommending you in the future.

I was nervous, but felt a ease straight away. I had a lot of questions which were always answered. Saw great results after 2 treatments, I would recommend SkinFirst to my friends.

I have always felt very welcome when visiting the clinic. The service was excellent and I am very pleased with how quickly I got results.

Excellent introduction, I was put as ease and the course was clearly explained. Very professional, I felt that June gave that little extra in my treatment. I have used many treatments and anti-biotics with little or no improvement over a 35 years period. The results during and at the end of the course of 6 treatments goes beyond my expectations. My only wish is that I had done this 30 years ago. My thanks and gratitude to all at SkinFirst.

Wonderful night, extremely informative. Friendly girls with lots of advice, thank you very much to you all and see you all again soon.

I have found my skin tone improved immensely and my skin felt moisturized and hydrated, I would definitely recommend SkinFirst to my friends.

I am so impressed with the treatment and love the way that it works in a non-aggressive manner. From previous laser hair sessions I was always left with burnt, damaged hair and slight skin redness and scabbing following a treatment which looked unsightly for a couple of weeks whilst the hair was worked out of the skin. Your treatment worked without any of these nasty side effects… really impressed!

I had a Radio Frequency treatment and I couldn’t believe my husband even noticed! He said it looked a lot smoother and tighter around the jaw line and on the cheek area and he said it looked younger! The results are amazing, I can’t believe that was after only one treatment!

I was a little nervous about coming in for a treatment as I’ve never had anything like this before, but I was put at ease immediately. I can honestly say I really enjoyed the whole experience – Natalie was lovely, and very understanding. I was having laser hair removal on my bikini and she was so professional and I hardly felt anything. It was 2 weeks ago and I have already seen an amazing result with patches where there is no hair. I will definitely be booking in for my underarms and legs now I know how good the results are. Thanks so much and I wish I had done this ages ago!

Results were fantastic – even after a couple of sessions. It’s like a miracle! No longer do I have to shave thick black hairs on a daily basis.

Thoroughly professional atmosphere and treatments.

For the first time in years I don’t have to wear make-up. I have had spots for most of my life and can’t believe how my skin looks now. Thanks so much!

I would definitely recommend the laser hair removal given by SkinFirst. It has completely changed my life. The service is excellent, staff very friendly and I have complete confidence in them.

I have fair skin & dark hair, after having just four sessions of the SkinFirst MPL machine. I have seen such a difference, the hair growth has slowed down so much I hardly have to shave, on some area’s like my underarms and bikini line there is no hair there any more, Its permanently gone!

Thank you so much for such a reasonable priced treatments, such good response.

My Birthday was coming up so I wanted a special treat for myself. So I called Skin First. I was welcomed with a warm reception and a glass of cold champagne.

I must admit I felt a little nervous, but everything was explained to me and I was soon looking forward to having a treatment done.My skin felt so much better and softer and I certainly saw an improvement in my skin.

I would recommend a visit to Skin First to everyone. I’m looking forward to my next appointment.

I go here for my MPL face laser treatment and I have to say Izzy is amazing! Pain free and you feel like your getting a mini facial! I love it and will always to go to SkinFirst.

Warm, comfortable surroundings and amazing treatment!

I highly recommend SkinFirst. It’s a lovely place, they make you feel really comfortable and provide all the info you need. I’m definitely going back for more treatments!

I love the results I am getting from their hair removal treatment! It does not hurt and the results can be seen straight away! Millie is amazing and the advice received is extremely useful. I would obviously recommend it to anyone wanting to get rid off any unwanted hair.

Absolutely amazing! Izzy is a credit – makes each visit brilliant by caring and making sure you’re well looked after. Can’t wait for my 4th visit in December! Thanks so much for each treatment. It’s lovely and clean & relaxing environment. Highly recommend to anyone.

I have been going to Skinfirst for a couple of months now and would highly recommend them. The dual radio frequency works absolute wonders on your face and is so relaxing. My skin is much more smooth, and so much more youthful looking, lines are far less obvious. Hair removal is so effective, very happy with legs and bikini. All treatments are very competitively priced.

Millie is so friendly, professional and puts you at ease straight away. The whole environment is very relaxing. I will continue to use Skinfirst on a regular basis. Thank you so much Millie.

The laser hair removal I’m having will be truly life changing when it’s complete, and my first radio frequency tonight was wonderful – can’t recommend it enough! Lovely staff and premises too, always enjoy my visits.

From the moment I walked through the door Millie put me at ease! The atmosphere is calm and relaxing, Millie is friendly, professional and knowledgeable.

The best bit? The laser hair removal is quick, painless and works! Can’t recommend it highly enough!

First visit to SkinFirst, so impressed with my facial by Izzy.

So relaxing, lovely welcome. Thank you x
