I had restylane injected into my cheeks and smile lines. I was so excited the first day because all my laugh lines had disappeared! 3 days later they started to return and at that point I realized that there had been swelling at the injection site causing the lines to smooth out. A week later I could tell that the lines were not as noticeable but still there. I can tell a difference but no one else would be able to tell I had something done. It's been 3 months and it's starting to dissolve.
To keep this up, I will have to spend upwards of $1500 to $2000 a year on filler. That's crazy. I can get a facelift and have permanent results for the same price as a few years of filler. I will start saving my money and go for the real thing in a couple of years. So, bottom line, if you have money to burn then fillers are great. They can, however, only do so much.
