At age 47, I had some mild sagging in my nasolabial areas on my face...no deep wrinkles, however.
After several consults with a variety of different doctors, I opted for Restylane. My first syringe cost $400, but we only used half of it, and 6 months later, I went back for the other half. I repeated this protocol the following year, and as I near age 50, I still have a good result. The pain was mild, but I took no numbing cream or other form of anesthetic.
The Restylane helped to fill out my lower face and when I smile (even a BIG smile), there are no major smile lines. The look is very natural and I would do it again.
