Blu-U (PDT) Acne Treatment
The Blu-U acne treatment delivers incoherent light at wavelengths of 400-450 nm. This light targets an organic compound generated by the p.acnes bacteria (Propionibacterium acnes) called porphyrins. As a result, when this organic compound is stimulated by the Blu-U light, singlet oxygen is produced which kills the p.acnes bacteria which causes inflammation. Although the Blu-U acne treatment is used alone, for severe acne the Blu-U light is often combined with PDT for best results (ALA Photodynamic Therapy).
What Is Blu-U With PDT
PDT is a topical photosensitizing agent which is absorbed by abnormal cells, pores, and oil glands. PDT makes these areas more susceptible to the acne treatment. BLU-U and PDT is considered the most effective acne treatment that does not depend on oral medication to treat acne.
Overall, ALA Photodynamic therapy is an effective acne treatment because it is able to:
1. Partially destroying over active sebaceous glands.
2. Accelerate corneocyte shedding, inhibiting new comedone formation (exfoliation/light peeling).
3. Kill the p.acnes bacteria which causes the inflammation.
Normally 3-6 acne treatments are required for best results.
