As with most skin treatments, there is not a one size fits all answer. You will see results in as little as one IPL Photofacial treatment; however, more than one treatment may be necessary depending on your skin concern. Typically, anywhere from two to four treatments will be enough to treat the majority of skin discoloration issues. In more severe cases, more than four treatments may be necessary. Reach out to a skincare provider any they will be able to help give you a customized quote based on your skin condition and goals.
