Visit your local doctor or dentist who is fully certified to safely treat you with dermal fillers. Your nurse will inject you with a natural gel so you can leave with confidence. Dermal fillers are not permanent but depending on the type of dermal filler you get your results can last anywhere from 6 months to 2 years. Wow! This will keep you smiling and when you need to go back for more treatments, you already know what to expect.
