Another question that patients ask is, “How long will it last?”
Well, let’s remember that this is caused by melanin and melanin occurs naturally in our body. So, the black or brown pigmentation is really always occurring in our body. With the laser, we’re just removing – layer by layer – the dark pigments that we see. Therefore, we all produce melanin at a different time schedule. Recurrence will be different for everybody. We’re expecting though about one and a half to three years though.
Retreatment is fine. It doesn’t hurt to go back in again to do the procedure. However, exciting things are happening on the horizon because they are trying to develop methods to actually inhibit melanin formation in our body which would then stop it from coming back forever.
