Can plasma pen give me a more defined nose? Slim down? (photos)

​I recommend getting a formal evaluation with a cosmetic dermatologist to go over your desired results. Facial fillers (like Voluma, Restylane, Juvederm) can be used to improve the symmetry of the nose, but surgery would be needed to improve nostrils or overall shape. Best to see an expert. - Dr. Emer​

No, you will need surgery to change the shape of your nose. Plasma pen is for texturing skin to improve fine lines and pore size on the nose.
