Acne or its severe form, Acne Vulgaris, is the most common skin disorder that affects an estimated of more than 75% of the US population today. In addition, Acne is thought to be the cause of more than 35% of all visits to the dermatologist in the US each year. So the need for a cure is quite obvious :-)

Lately there are more and more opinions to get rid of antibiotics in order to treat Acne.

The bacteria, Propionibacterium acnes, which is the main cause of Acne vulgaris, has developed resistant species, turning antibiotics to be quite ineffective…

Instead, other non-antibiotic alternatives are emerging that offer valuable more & safe cure…

Lately, a light based technology treatment called Photodynamic Therapy (PDT) is under a vast investigation as an effective treatment for Acne Vulgaris. The long term results shown by the PDT solution has made it a promising alternative to the other long term effective Isotretinoin (Accutane) treatment.

The Photodynamic Therapy Acne Treatment (PDT)

Photodynamic therapy (PDT) is a non-invasive, new form of light based therapy that utilizes laser technology to achieve a light induced chain of cell chemical events to cause selective tissue cell destruction.

Currently the Photodynamic therapy (PDT) is approved by the FDA (the U.S. Food and Drug Administration) to treat various thin superficial skin cancers called actinic keratoses.

It is now being studied as an effective and most safe solution for Acne with little or no side effects as a result of the treatment.

What is the Purpose of  the Photodynamic Therapy (PDT)?

PDT is considered as a specific targeted cell destructive treatment. The nearby cell destruction caused by the procedure, induce the following changes that improve the Acne status in both severe to mild cases of the disorder:

1) It kills the Propionibacterium acnes cells (the bacteria causing Acne Vulgaris).

2) It shrinks the oil glands in the skin’s face and neck, allowing to reduce the amount of oil production in the skin pores, same as in the case of  Isotretinoin.

3) It normalizes the clogging of dead cells inside the hair follicle.

4) It also improves the overall skin tone and texture, allowing the Acne scars to heal and become invisible.

How does the Photodynamic Therapy (PDT) Work?

The Photodynamic Therapy (PDT) is based on a photosensitizing agent, applied to the inner skin layers that is then activated by light exposure in a specific wavelength in order to generate a chemical reaction that cause nearby death of the cells…

If a cell containing a photosensitizer agent is exposed to a light in a specific wavelength, it absorbs the light and becomes activated. Now, if that activated photosensitizer agent is close to an oxygen molecule, it will transfer the energy to the oxygen molecule in a chemical reaction and cause the oxygen molecule to be highly reactive and unstable.

This extremely unstable oxygen molecule may damage and hurt the surrounding cells, causing eventually, the death of these cells…

Usually, this oxidant unstable oxygen molecule is problematic and may cause cancer in some cases (if not treated by the cells defend mechanisms), but in this case it is beneficial as it helps to destruct the  Propionibacterium acnes bacteria cells. In addition, since the Propionibacterium acnes bacteria is considered as a photosensitive microorganism, the result is much effective. Of course, the nearby oil glands are also reduced in their size, allowing less production of oil as mentioned above.

Photodynamic Therapy (PDT) Treatment Procedure

The PDT treatment consists of 3 main steps:

1) The admission of the photosensitizer agent – The photosensitizer agent is applied and penetrated into the problematic skin cells area. During this procedure, the thick layer of dead cells is sometimes removed to allow best penetration.

2) Incubation – The photosensitizer agent is kept in the cells in order to penetrate well into the affected area for best results. This may take usually between 60 to 90 minutes, depending on the severity.

3) Light Exposure – The entire problematic skin tissue is exposed to a light in a specific wavelength, allowing an activation of the inside tissue photosensitizer agent which will start the chemical reaction and turn nearby oxygen molecules to be unstable.


Note that the 3 step treatment must be repeated 3 to 4 times within an interval of a couple of weeks in order to achieve maximum results. Of course, the number of repetitions needed depends on the severity of the Acne.

Side effects reported by patients who used this treatment include some redness and sunburn feeling after the treatment. The symptoms are usually gone within a matter of days.

The results reported by patients are extremely promising, considering the treatment of Acne Vulgaris, cysts and scars that were eliminated very quickly.

It is by far the most promising solution to Acne at current time, which yields results quite similar to Accutane but with less complications and side effects…

P.S – Acne is one of the most common skin disorders in the world at current time. Since the use of topical & ural antibiotics is less preferred due to its lack of effectiveness, other alternatives have emerged… If you do not want the Photodynamic therapy because you are afraid or because it is too expensive, why don’t you consider the all natural Revitol Acnezine solution – Please read the thorough in-depth review analysis to learn more…
