Contraindications are rare when utilizing lasers and light sources for the treatment of medical dermatologie conditions with or without ALA-PDT. As with all laser and light treatments, patient expectations must be carefully ad dressed. Multiple treatments are often required to produce optimal results. Maintenance therapies will also be required in most instances.
Most laser physicians would not recommend the use of oral isotretinoin when performing laser and light treatments. Whether this is an absolute contraindication is open for debate, but caution should be used if oral isotretinoin is used during these laser or light procedures.
