Keratosis Pilaris

Keratosis Pilaris is one of the most common skin conditions in the world. It is believed to affect 50-80 percent of teens and up to 40 percent of adults worldwide.

Sunflower Dermatology offers photodynamic therapy (PDT) to treat pre-cancers and certain skin cancers. PDT uses specialized drugs, called photosensitizing agents, and light, to kill precancerous, and cancerous skin cells. This procedure has been used to safely treat cancer for more than 100 years.

Depending on the body part to be treated, the photosensitizing agent (ALA or Levulan) is applied to the skin and left to sit for between 2-4 hours. Because this product is activated by sunlight, the patient is often asked to stay in our Riverside, MO office during this process. Each patient is placed under a blue light for 16 minutes and 40 seconds to commence the treatment. After photodynamic treatment , patients should avoid exposure to sunlight, and apply physical sun protection. Side effects of photodynamic therapy can include pain and swelling at the treatment sites. Advantages include: no long-term side effects; surgery is not required; pre-cancers, and cancers, will be prevented at the site of treatment.

Rosacea is a common, chronic, disorder characterized by facial flushing, persistent redness, papules, pustules, and telangiectasia. Though women more commonly have the condition, men may have it more seriously. This condition not only affects the face, it can also affect the eyes. W.C. Fields had rosacea, which caused his thickened nose. The cause of rosacea is unknown.

Triggers for the condition include sun exposure, spicy foods, alcohol, hot beverages, stress and heat. Therapy includes topical and oral medicine, plus the regular use of sunscreen to avoid flares.

UV Light Therapy, or Phototherapy, involves exposing skin to ultraviolet light on a regular basis and under medical supervision. Sunflower Dermatology offers advanced UV light therapy treatment using narrow band ultraviolet light (UVB.) This treatment can be individualized to discrete, localized, areas using our laser or, for patients who have widespread involvement, our stand up total body light box. This treatment differs from tanning beds, and natural sunlight, because it uses one specific, and most effective, wavelength to treat psoriasis. In addition, because it uses just this one wavelength, it is a safer alternative to tanning beds, or sunlight, because it has a decreased risk of skin cancer and premature skin aging. Phototherapy is the primary treatment for psoriasis and can be used as an adjunct treatment to topical medication. Setting and frequency of treatment are individualized for each patient.
