Photodynamic therapy (PDT) has been proven to be the only treatment with long term improvements in cases of mild acne and severe acne. PDT replicates the natural process that occurs with exposure to sunlight. Sunlight kills acne bacteria by the activation of Aminolevulinic Acid (ALA).

This natural process is replicated by applying Aminolevulinic Acid (ALA) to the skin which is then activated by the Omnilux light. Two to three treatments are required for optimal results, 2 – 4 weeks apart. Longer ALA application results in increased downtime, however leads to better results.
