Photofacial is a procedure done using the Intense Pulsed Light system, which uses a range of wavelengths to work on the skin - it helps in treating sun spots, broken capillaries, and facial redness. Some call LED light therapy, as a form of photofacial too. This is used in acne treatment. In contrast, a radiofrequency system can be ablative - where it is used for removing benign skin growths, spider veins, and the non ablative version, which is used for skin tightening, wrinkle improvement and body contouring in one of two forms - monopolar and bipolar. The way each (photofacial/ RF) acts is different, and the reason why each is employed is also different. If you mentioned what you wanted done for your face/skin, your dermatologist will be able to help you with the best option. Good luck!
