Treating Acne with PDT (Photodynamic Therapy)

Photodynamic Therapy (PDT) is an effective acne treatment

Photodynamic therapy (PDT) involves the application of a cream called Aminolevulinic Acid (ALA) which is activated by a light source. At Cosmos Clinic we use Omnilux. Aminolevulinic Acid (ALA) is a “natural” product found throughout the body. The activation of ALA by light leads to:

• The destruction of sebaceous glands. The blockage of these glands is responsible for causing acne.
• The destruction of Propionibacterium acnes (P. acnes), the bacteria that triggers acne.
• Improved texture, tone and complexion of the skin. It reduces pigmentation, broken capillaries and fine lines.

This makes Photodynamic therapy particularly useful for acne, Rosacea, pigmentation (freckles), large pores and photorejuvination of the skin. It can be used for all skin types over the whole body. The use of Retin A gel and fruit acids prior to the PDT helps with the effectiveness of the treatment.

After the procedure, it is important for the patient to avoid the sun where possible, wear sunscreen and a hat. Exposure to the sun will result in a burning sensation on the face (photosensitivity).

The face becomes red a few hours after the treatment. The photosensitivity and the redness will last anywhere from two days to two weeks depending on the intensity of the treatment selected by the patient. The greater the intensity, the better the result, but the longer the redness and photosensitivity.

What is ALA Photodynamic Therapy Treatment (PDT)?

Photodynamic Therapy Treatment (PDT) is a process by which a photosensitising cream called Aminolevulinic Acid (ALA) is applied to your skin and then activated by a light source. The Photosensitising cream is a special solution that is activated by a red or blue light, which “turns it on”. ALA is a “natural” product found throughout the body. It is needed for haemoglobin synthesis. (It wouldn’t be possible to make the red blood cells to carry oxygen without ALA in your body.)

What is Photodynamic Therapy used for?

Photodynamic Therapy (PDT) is useful for the treatment of acne, rosacea and pigmentation (freckles). It is also used for photorejuvination of sun damaged skin to improve the texture, tone and complexion while reducing the pigmentation, pores and fine lines of skin.

Does Photodynamic Therapy have any side effects?

There is no risk of scarring with PDT.

Some patients may experience marked redness of their skin which will resolve. Temporary swelling may occur with the lips and around the eyes for a few days. Darker pigmented patches, called liver spots, can become temporarily darker and then peel off leaving normal skin. (This usually occurs after seven to ten days).

It has no long term side effects when used properly by a cosmetic physician

How much does Photodynamic Therapy Cost?

The cost ranges from $330 to $1100 depending on the desired effect. If minimal downtime (1-2 days) is requested the cost is $550. If moderate downtime (1 week) is requested the cost is $895. If maximal downtime (2 weeks) is requested the cost is $1100.
