They also cover key uses along with adverse effects such as phototoxicity and pigment alteration. In the main segment, they explore actinic keratosis as a chronic disease, the importance of field therapy, and how to set expectations. Dr Trotter also shares practical pearls for optimizing outcomes and tailoring PDT in clinic.
