The No.14 can be used in Aesthetic procedures such as "Dermaplaning" which helps to "refinish" the skin's top layers through a method of controlled surgical scraping which exfoliates the epidermis . It is complemented by the smaller more rounded 10R "butter blades" .
 
Dermaplaning can be performed on small areas of skin or on the entire face and can be used alone or in conjunction with other procedures such as a chemical peel, microdermabrasion, or fluorescent pulsed light (FPL). Dermaplaning, when performed prior to other treatments, can remove the "peach fuzz" which can trap excess dirt and oil. 

It is non-invasive and helps make other skin treatments more effective.
