Levulan® Kerastick® (aminolevulinic acid HCl) for Topical Solution, 20% (Levulan Kerastick) plus blue light illumination using the BLU-U® Blue Light Photodynamic Therapy Illuminator (Levulan PDT) is indicated for the treatment of minimally to moderately thick actinic keratosis of the face or scalp. Actinic keratoses (AKs) are rough-textured, dry, scaly patches on the skin that can lead to skin cancer. It is important to treat AKs because there is no way to tell when or which lesions will progress to squamous cell carcinoma (SCC), the second most common form of skin cancer. So, now’s the time to manage your damage!
Levulan PDT, a 2-part treatment, is unique because it uses a light activated drug therapy to destroy AKs. How does it work? Levulan Kerastick Topical Solution is applied to the AK. The solution is then absorbed by the AK cells where it is converted to a chemical that makes the cells extremely sensitive to light. When the AK cells are exposed to the BLU-U Blue Light Illuminator, a reaction occurs which destroys the AK cells.
The 2-part treatment offers the following conveniences:
Levulan PDT can also fit your lifestyle:
*Patients treated with Levulan PDT should avoid exposure of the photosensitized lesions to sunlight or prolonged or intense light for at least 40 hours.
Up to 58 million Americans have actinic keratosis (AK). An AK has the potential to progress to squamous cell carcinoma (SCC), the second most common skin cancer. While most AKs remain benign, approximately 10 percent develop into SCC within an average of two years.1 Since there is no way to know ahead of time which ones will become cancerous. Frequent skin examinations are the key to early detection and prevention.
AKs – often called “sun spots”— are rough-textured, dry, scaly patches on the skin caused by excessive exposure to ultraviolet light (UV) such as sunlight. They occur most often on sun exposed Actinic Keratoses generally begin as rough spots of skin that may be easier felt than seen. Common complaints include a lesion that has increased in size or one that is raised, bleeding, poor in healing, discolored, or associated with discomfort such as pain or itching.
While a lesion may initially appear skin colored to pink, red, or brown, lesions on darker skin may be more pigmented. AKs may feel soft, rough, or “gritty,” but in any case, they feel different from the surrounding healthy skin. AKs are seen primarily in Caucasians with pale skin living in sunny climates. Areas of the skin with the most sun exposure, such as the head, neck, forearms, and hands account for more than 80 percent of AKs.
Actinic Keratoses develop as the result of years of sun exposure. Because the effect of sun exposure is cumulative, it is your lifetime exposure that increases your risk. Even if you didn’t suntan much, years of just doing simple tasks outside can add up to significant amount of sun exposures. For example:
Because AKs take a long time to develop, they generally appear after the age of 40. The American Academy of Dermatology estimates that 60 percent of persons apt to get Actinic Keratoses will indeed get at least one AK in their lifetime.
Your risk of developing AKs increases if you have one or more of the risk factors.
