An IPL treatment can leave lasting results in as little as one treatment, as long as a good skincare routine is maintained following the treatment. An IPL Photofacial is a procedure that helps even out skin tone and eliminate unwanted dark marks and pigmentation. These results can last for years after the treatment is completed. However, as the skin ages, so does the body’s ability to produce collagen and elasticity. This is a normal part of the aging process, but may result in a patient wanting to come in for additional treatments at a future date.
