Hyaluronic acid fillers like Belotero should have an immediate effect after the injection.
The best result is typically seen 2 to 4 weeks after filler injection as it takes time for the product to integrate into your tissue.
As a result, most doctors will review their customers 2 to 3 weeks after filler injection to make sure everything is good.
Your doctor might have under filled your dents and sometimes a little touch up will be needed. Go back for a review and consult your injector. It will also be helpful if you can show a picture of the treated areas. All the best!
