Treatment times will vary depending on individual skin condition and the size of the area being treated. Generally, a single treatment session may take between 30 minutes and 1 hour. 

Most people see noticeable improvements after a few treatments, including smoother, more refined skin, fewer fine lines and wrinkles, and a more even skin tone. However, specific results will vary from person to person and are affected by a variety of factors, such as age, skin type, lifestyle, etc. 

Dermapen's high-speed vibration design helps reduce pain. Most people only feel a slight stinging or discomfort during treatment. For people who are sensitive to pain, your doctor can provide local anesthesia or other pain relief methods. 

The frequency of treatment will also depend on the individual's skin condition and needs. Generally speaking, it is recommended to have a treatment every 2-4 weeks until satisfactory results are achieved. After that, maintenance treatments can be performed as needed.
