Since fillers last about a year, depending on different factors, all you'll need to maintain your results is a treatment each year. Of course, this may be only several months or even longer than a year, depending on the factors mentioned in the section above. It's not really about how long a filler will last for, though; it's mostly about which one will work best for you and your needs! We can help you with your decision here at Wellness Center of Greater Cleveland.
