This is a newer laser procedure that smooths, plumps and tightens. Instead of fillers I opted to try the Fotana 4D treatment to plump my nasiolabial folds. The Fotana 4D uses 4 different lasers, thus giving me plumped up nasiolabial folds, fresher looking skin and a reduction in my wrinkles. The initial laser is intraoral. It is used in the oral cavity around the inside or your mouth/cheeks....
