I’ve been using the Photizo light for the past 8 years, with great results, personally and professionally. We used it on patients after they had an operation. Their pain was considerably less and their wounds healed faster than with patients that didn’t use it. Recently my cat had an abscess in the face and within a day the light made the abscess drain, and healed it within 5 days to a dry scab. I would recommend the Photizo light to anyone.
