Is there an effective treatment for cold sores?

Research suggests that the majority of cold sore sufferers have become disillusioned having tried at least three cold sore remedies, which did not work.

Topical antiviral ointments are only moderately effective if applied during the very early tingling phase of the onset of a cold sore and are otherwise of no use. These ointments are messy and require repeated applications, which are inconvenient and expensive.

"Miracle Cure" solutions and ointments are hopeless and do not have any published clinical trial information on which to base a rational decision to purchase and try them out.
In March 2001 a clinical paper was published in the Journal of Clinical and Experimental Dermatology, an official journal of the British Association of Dermatology, the clinical trial demonstrated unequivocally that a new therapeutic technology reduced cold sore healing time by 50% compared to a topical antiviral ointment.

This new therapeutic technology was discovered by researchers at "Virulite Ltd" who analysed the effect of invisible narrow waveband infra red spectrum of light on cold sore healing times.

One particular narrow waveband of light was found to be effective and this has been incorporated into the "Cold Sore Machine" cold sore treatment device.

If you suffer from embarrassing recurrent cold sores and are dreading the next attack you will be familiar with that apprehensive feeling. You know that within the next few weeks or even hours a cold sore will appear to spoil your day!

A sunny holiday abroad or ski trip
Meeting a new date
Family worries
Under pressure at work
Feeling "off colour"
Any of these factors will reduce your immunity to such an extent that the dreaded herpes simplex virus can take control!


By using the new Cold Sore Machine treatment device you have the energy to restore local immunity to normal levels to prevent the cold sore even appearing, or to banish it quickly if it has already erupted.

If you do consider purchasing a Cold Sore Machine you can be confident in the knowledge that the treatment device was only developed after the results of controlled clinical trials were found to have been successful.


  • It works and has been medically proven to work with no recorded side effects 
  • Reduces cold sore healing time by half compared to aciclovir antiviral ointment 
  • In the majority of cases only 2 treatment cycles per cold sore is required 
  • Does not require the application of messy ointments

The Cold Sore Machine uses a breakthrough in medical technology, the result of 10 years of clinical research. Over the 10-year period the researchers of Virulite Ltd experimented with many wavelengths of light to ascertain if any had therapeutic potential. Finally it was discovered that light centred at a wavelength of 1072 nanometers had a powerful therapeutic effect. This phenomenon was clearly demonstrated in a clinical trial conducted at a North East hospital where topical aciclovir applied five times daily was compared to a single application of the 1072nm light. The invisible light treatment halved cold sore healing time as compared to topical aciclovir.

Q. How can a light heal my cold sore?

We believe that the 1072NWB light acts as a catalyst, which enhances the local immune response, which allows the body to heal itself more rapidly.

Q. Why can't I just stand in the sunlight to heal my cold sore?
Sunlight Contains UV (ultraviolet light), which actually causes cold sores to occur, this can make your cold sores worse. The amount of 1072NWB light in sunlight in the UK (even in summer) is insufficient to be effective.

Q. Will any light do as long as I put it on my cold sore?

No, over the last 10 years Virulite Ltd has been researching the various wavelengths (colours) of light in the visible and invisible spectrum and found some wavelengths were ineffective and some even make cold sores worse! Only 1072NWB light proved to be effective in reducing cold sore healing time.

Q. Is this new treatment a cure or just another treatment?
The clinical evidence proves that this is a superior treatment, however ongoing research by Virulite Ltd has given rise to strong anecdotal evidence that if used to treat 4 to 5 separate cold sore attacks, the recurrence of the cold sores is significantly reduced. This is the focus of ongoing research. The Cold Sore Machine is highly effective in 99.5% of individuals.

Q. When and how many times can I treat my cold sore?
You should treat your cold sore as soon as you become aware of it (blister or tingling stage) and then treat it 12 hours later. In the majority of people this is an adequate treatment, however in a small percentage of people the virus takes a little longer to travel down the nerve to the skin. The 1072NWB light therapy is only effective in the presence of the virus, thus if the cold sore appears to progress after the second treatment it is best to treat four more times a day for 2 days. There is no limit to how many times a cold sore can be treated, but treating more often is not recommended as it is of no proven clinical benefit.

Q. What about safety and long-term effects?
The wavelength used by the Cold Sore Machine is very close to that of the Nd:YAG laser which has been used by doctors all over the world for several decades. The Cold Sore Machine radiates divergent light which is inherently 'eye-safe' and uses powers 1/10 000 less than the medical lasers already in use. It has been documented in medical papers that Nd:YAG laser surgery to a pregnant woman's cervix (neck of the womb) is a safe procedure if clinically indicated. The cervix is very close to the developing baby.

Q. Is it safe to use on children?
The Cold Sore Machine is safe to use on children, the time of application remains unchanged at 3 minutes.

Q. Are there any side effects?
No side effects or complications have been documented.

Q. What about the site of the cold sore?
The invisible light that the Cold Sore Machine uses penetrates the skin relatively easily, thus can treat cold sores in the nose, inside the lip and on the face as effectively as cold sores that are present on the outside of the lips.

Q. Can the Cold Sore Machine be used on cold sores of the skin (leg, buttock etc)?
Dermal herpes should in theory respond to the Cold Sore Machine, although this has not been verified in clinical trials. Daily treatments for 4 consecutive days are recommended.

Q. What about genital herpes?
The Herpes simplex 2 virus usually causes this condition. Theoretically, provided the light can be applied directly to the blistered area it should be an effective treatment, however clinical trials have not been conducted verifying this. Daily application for 7 consecutive days is recommended.

Q. What about mouth ulcers?
Whilst not medically proven, 2 treatments daily for 2 days has been found to be effective in the treatment of aphthous ulcers.

Q. How Does the Cold Sore Machine work?
The researchers at Virulite Ltd know that the light has no effect upon the actual virus but does have a positive effect upon the immune cells responsible for fighting the virus. It is also known that the Cold Sore Machine light plays a role in generating powerful antioxidants within the cells. This is a field of active research.

Q. Does the Cold Sore Machine help relieve pain?
In some individuals their cold sores are accompanied by severe pain, our research demonstrated that in the majority of these individuals almost complete pain relief occurs within the period of the 3-minute treatment cycle.

Q. What is the shelf life?
The Cold Sore Machine will deliver unlimited cold sore treatments whilst under warranty (the Cold Sore Machine can only be used on 1 end user), each lasting 3 minutes; the battery is replacable The manufacturer's guarantee is for 1 year. The Cold Sore Machine device has an internal mini-computer, which monitors the invisible light output and will shut the device down if inadequate light is generated. This safety feature prevents the user using an ineffective device.

Q. Does the Cold Sore Machine need batteries?

Yes, the Cold Sore Machine comes with a battery which treats approximately 10-20 cold sores.

Q. Is the Cold Sore Machine available on NHS prescription?
Not at present, we are in the process of applying for this product to go on NHS prescription, but as of yet the time scale is unknown.

A pilot study of treatment of herpes labialis with 1072 nm narrow waveband light.

Dougal GKelly P.

Occupational Health Department, North Tees Hospital, Stockton-on-Tees, UK.

Erratum in:

  • Clin Exp Dermatol 2001 May;26(3):312.


A randomized prospective double-blind study was performed to compare the efficacy of a single 5 min 1072 nm narrow waveband light application against topical aciclovir applied five times daily in the treatment of herpes labialis. Treatment was initiated within 36 h of the onset of symptoms and the end point was defined as the day that the crust was discarded leaving an uninterrupted underlying skin at the site of the cold sore. The results demonstrated that a single 5 min light treatment significantly reduced cold sore healing time by 4 days; 1072 nm light healed cold sores in 4.3 +/- 1.8 days (mean +/- SD) as compared with aciclovir applied five times daily, 8.5 +/- 3.0 days (P < 0.0001).
