If I get striped during IPL, will I have to pay more to have the procedure done again to fix the striping?

If there is striping from inadequate overlap, that should be corrected at no charge. Most often. If you are scheduled for multiple IPL treatments, one of your follow up treatments can address the striping. If you are done with your treatments and a striped pattern persists, the practice should offer to correct this at no charge (in my opinion)
Hope this helps.

Sometimes due to not enough pressure being applied during a IPL treatment, you will develop squares or lines. These will go away on there on after about a week or so. A replacement treatment at our office would be what we do just because you wouldnt have received the best treatment originally.
