Yes, PDT is often combined with other acne treatments, such as topical creams and antibiotic pills.
PDT is most often used in cases of moderate to severe acne, treatment-resistant acne, or when Accutane or other oral treatments are not an option.
Patients typically require 1-3 treatment sessions, performed anywhere from 2-4 weeks apart, to achieve maximum results.
PDT often leaves the skin red and scaly for a few days after treatment, similar to the reaction you get with sunburn. The skin remains sensitive to light for 48 hours after the treatment, so be sure to wear sunscreen and protect your skin from excessive sun exposure during this time period.
Some patients do report minimal discomfort during PDT treatments. Topical anesthesia can be applied to make the treatments more comfortable.
