Hi Daovin,
There is no set time period that we can firmly guarantee Restylane lasting. It varies depending upon the area, the amount, the patient's activity level and metabolism.
It lasts longest in areas that are the least mobile. It commonly lasts for a year or more under the lower eyelids when tear trough depressions are corrected. It disappears quickest in the most mobile areas like the lip, quicker in those that move their lips a lot (less unnecessary chatting anyone?). I have heard some patients say that it lasted only two months in their lips, but usually it lasts 3-4 months in the lips. Patients that are very active and work out three times a day lose their Restylane faster that say a person that is inactive, say like a cadaver.
Then there is the amount that is injected, sometimes there is initial swelling regardless of the amount injected. When that swelling resolves, it looks as if the Restylane is gone, but perhaps there was not much put there in the first place.
It should last from 6 to up to 9 months. You may want to try the thicker form of Restylane called Perlane which some claim to last longer. Question how much Restylane you are receiving. It is also vital that your treating physician place the injections in the proper level of your skin. Good luck.
