Light Treatment for Active Acne In Upton Rocks

To many teenagers afflicted with this skin problem, acne is a four letter word!

While it is estimated that more than 80 percent of the world's population is affected by acne in various forms at some point during their life, there is still no cure.

It can cause considerable emotional stress, affecting self esteem and social lives, and occasionally lead to life long scarring of the skin.

Until recently, a combination of topical preparations and oral medications, including antibiotics, has been used almost exclusively with varying degrees of success to combat acne. In 2003 several laser and light-based technologies had been shown to improve mild to moderate acne in a few treatment sessions, and with no known systemic side effects.

If you are considering a light based treatment for improving acne, the following information will give you a basic understanding of the procedure. It can't answer all your questions, since a lot depends on the individual patient and the practitioner involved. Please ask a practitioner about anything you don't understand.

The commonest form, Acne vulgaris, typically begins in adolescence, although onset in the twenties or thirties is common, and it can range from the occasional flare-up of pimples or spots that do not require any treatments to severe cases that can cause scarring and psychological problems.

If one looks very closely at the facial skin of teenagers, up to 90% have some form of blackheads or mild spots.

Moderately severe acne, i.e. with lots of inflamed spots on the face and upper trunk, affect around 5% of teenagers.

Acne usually starts around the age of 12 to 13 in girls and slightly later in boys.

There is some evidence to suggest that acne is more common amongst some families, suggesting that genetic factors are important.

Occasionally acne affects babies (so called infantile acne), and chemical or drug induced acne can affect anyone. Certain cosmetics, or oral and topical steroids can also result in an outbreak of acne.

Many acne sufferers recognise that small amounts of sun exposure may initially improve the appearance of acne, and as the skin darkens, blemishes may be less noticeable. However, prolonged exposure promotes more rapid exfoliation of dead skin cells, so you’re more likely to get clogged pores. In addition, acne’s unsightly souvenirs, post-inflammatory hyperpigmentation and macules, will actually get darker if you spend time in the sun.

Over time, sun damages the skin and increases the likelihood that your acne will leave scars as well as increase your chances of getting some form of skin cancer.

In 2003 clinical trials allowed a number of machines utilising light for the treatment of active acne to receive FDA (Food and Drugs Administration) approval in the US – allowing the companies to promote their device for the treatment of this skin disease.

There are two main approaches which are being used and evaluated clinically:

1) The use of light to kill bacteria

The first of these approaches targets the bacteria that produces the inflammation associated with acne - Propionobacterium Acnes, or P. acnes.

Porphyrins are naturally occurring molecules that reside alongside the P.Acne bacteria in the infected pore. Porphyrins are photosensitive and light of certain colours can cause the release of oxygen from this molecule which destroys the anaerobic P.acnes bacteria. (It is thought that this is how natural sunlight also helps to improve acne).

2) The use of light to reduce the production of sebum

Another way to treat acne using laser technology is to damage the sebaceous (oil) glands in the skin by a thermal or heat effect.

Skin samples taken immediately after treatment with certain types of lasers show heat-induced changes of the sebaceous glands, reducing the amount of oil produced.

The laser emits a wavelength of light that is strongly absorbed by water within the skin. This generates heat in and around the sebaceous glands. By creating a mild thermal injury just below the skin’s surface, a laser can alter the structure and function of the sebaceous gland, leading to prolonged acne clearance.

Photodynamic Therapy (PDT)

Photodynamic therapy using a cream called aminolevulinic acid (ALA) has been approved by the Food and Drug Administration (FDA) to treat actinic keratosis, an early potential sign of skin cancer.

In the process of laser PDT for the treatment of acne, aminolevulenic acid or ALA, is applied to the skin.

This is absorbed preferentially by certain structures in the skin, such as hair follicles, oil glands, bacteria, or rapidly growing cells. Illumination with a high-intensity light (red light) or laser/IPL causes a reaction in the skin, resulting in destruction of the targeted tissue.

Photodynamic therapy seems to improve acne by decreasing the bacteria on the skin and by shrinking the oil-producing sebaceous glands.

What are Lasers?
A Laser is a high-energy beam of light that can transfer its energy into specific areas of the skin’s tissue to treat skin problems. These beams of light are produced in one wavelength or colour at a time, and can vary in terms of their strength and the type of tissue that they can target.
Some lasers work by killing the bacteria, and others help to reduce the production of sebum from the sebaceous glands in the skin.

What is Intense Pulsed Light (IPL)?
Intense Pulsed Light systems, although technically not lasers, use flashes of light that work in a similar way to lasers.

Their main affect appears to be antibacterial.

What is Light, Heat Energy (LHE)?
This is another treatment which you may hear mentioned. This also works by carefully controlled bursts of low-level light and heat that can help to destroy the P. acnes bacteria.

What are Light Emitting Diodes (LED)?
These can produce blue light that helps to destroy the P. acnes bacteria, and red light that can be used for Photodynamic Therapy (described above).

Additional investigational studies are ongoing with combination laser/Radiofrequency (electrical energy) systems.

Most patients will be able to return to work immediately following the procedure.

It is highly unlikely that anyone considering light based treatment to improve their acne would be able to access this free of charge on the National Health Service at this point in time.

Private prices for acne treatment using light vary depending upon the light source used, and your particular treatment requirements.

Costs can be in the £75 - £300 range per treatment session.

Patients generally not suitable for any form of light treatment are those who have a history of keloid scarring (overgrowth of scar tissue), an active herpes infection (cold sores) or other skin infections such as impetigo at the site to be treated.

You would also not be suitable if you have a history of sensitivity to light that may cause your skin to develop a rash or any other reaction.

Patients who have used isotretinoin in the last year would also not be suitable candidates.

Darker skin, or recently tanned skin, may be not be suitable for treatment by certain types of machine. Your practitioner will advise you about this if you have a darker complexion.

If you are worried about your acne, discuss it with your General Practitioner. If it is really severe, he/she may refer you on to see a dermatologist.

If you have been prescribed a treatment for your acne (whether a cream, lotion or tablet) remember that all of the treatments only work by preventing new spots and that all treatments have to be tried for at least four months before you decide whether they are helping.

Dabbing on a cream or lotion to existing spots when and if they appear is a waste of time.
Your acne treatment needs to be applied on a daily basis for a long time in order to exert its beneficial effects.

If you are concerned about poor results or side effects achieved with current treatment, you may want to explore the option of light based procedures.

The use of light technology alone or combined with PDT can offer clearance rates averaging between 50% and 90%.

The results seem to be comparable to oral antibiotics, but with the apparently reduced potential for systemic side effects.

Many private clinics and beauty salons are being persuaded to buy these systems and market them for acne.

Some machines may even find their way into the National Health Service.

In addition, various home use devices are available and marketed direct to the public in the UK as systems to use for the treatment of acne.

Advertising messages of clearance rates, treatment times, numbers of procedures required, doctor led or beautician initiated procedures and overall treatment costs will need to be carefully evaluated in order to clearly identify the benefits of purchasing this form of treatment.
