What are Levulan + Blue Light PDT?

Levulan Aminolevulinic Acid (20%) is a naturally occurring photosynthesizing agent, which has been designed to treat pre-cancerous lesions called actinic keratoses. If untreated AK’s may develop into skin cancer. Levulan is applied to the skin and then “activated” by blue light. This process is known as Photodynamic Therapy.



What are Actinic Keratoses?

Actinic Keratoses (AKs) are rough-textured, dry, scaly patches on the skin caused by excessive exposure to ultraviolet (UV) light, such as sunlight. They are often referred to as “sun spots” and they occur most frequently on sun-exposed areas such as the face, scalp, ears, neck, hands, and arms. They form on the outermost layer of skin and they can range in color from skin toned to reddish brown. They can also range in size from as small as a pinhead to larger than a quarter. More than 10 million Americans have AK lesions, with the majority occurring primarily in fair-skinned individuals.

Who gets AKs?

AKs develop as the result of years of sun exposure. Because it accumulates over time, it is your lifetime exposure that increases your risk. Even if you didn’t sun-tan much, years of just doing simple tasks outside (e.g. going out to the mailbox, sports, etc.) all add up to a significant amount of sun exposure. Because AKs take a long time to develop, they generally appear after the age of 40. Your risk of developing AKs increases if you have one or more of the risk factors. These risk factors include:

  • A history of cumulative sun exposure
  • Fair skin
  • Blonde or red hair, in particular, if combined with blue, hazel or green eyes
  • A tendency to freckle or burn after sun exposure
  • A weakened immune system

What do AK’s look like?

Approximately 90% of the outermost layer of skin (epidermis) is made up of tough walled cells called keratinocytes. It is these cells that give the skin its texture. When keratinocytes are exposed to years of sunlight, cell damage can occur. These cells then change in size, shape, as well as the way they are organized. AKs may range in appearance. They can be light or dark, the same color as one’s skin, tan, pink, red, or even a combination of these. They can also range in size and texture.

Why treat AKs?

AKs are considered to be the first step in the development of skin cancer. They have the potential to progress to squamous cell carcinoma which is generally not life-threatening if detected and treated early. In most cases, when AKs and all types of skin cancers are caught in the early stages, they are treatable and curable. That is why it is so important for individuals with AKs to be under a dermatologist’s care. Frequent skin examinations are the key to early detection.

What is acne, and why is it so hard to control?

There are many types of acne. The most common is called acne vulgaris.  Almost everyone goes through a period of acne at one time or another.  Just beneath the surface of the skin lie hundreds of tiny glands called

sebaceous glands. Their function is to collect and excrete the oily substance called sebum, to keep the skin healthy.  However, the tiny pathway for the sebum to escape often becomes clogged, and a bacterium called P. acnes grows inside. In a short time, the area swells up and forms a pimple on the skin.

At certain times of life, this process becomes very active, troublesome and hard to control.

Is there a new way to control moderate acne?

There are many treatments for moderate acne – creams, washes, medications – mild ones and very strong ones. However, your doctor may decide that certain medications, such as antibiotics, aren’t right for you. Your case of moderate acne may not be responding to medications or other conventional treatments. It may be hard for you to keep up with complicated routines of skin care. Maybe it’s time to consider something new.
