Photopneumatic therapy
Photopneumatic therapy
The photopneumatic technique involves pneumatic energy and broadband light (400โ 1,200 nm). With the help of suctioning, the dermis is brought upward toward the skinโs surface permitting more efficient energy absorption. This method lowers the risk of pigmentary changes. Photopneumatic therapy (PPX) operates based on thermal and vacuum physics effects. The suctioning creates negative pressure, which assists in the removal of comedones. This novel approach utilizes mechanical extrusion, along with photothermal and photochemical reactions, to treat mild to moderate acne.48
One study reported 90% clearance after four treatment sessions, in which a single session resulted in 50% clearance. PPX results in the extrusion of comedone contents from the infundibulum while decreasing sebaceous gland activity through its thermal effect. Further study is needed to better elucidate the role of PPX in acne treatment.49
