What is Best for Filling in Mild Malar Grooves?

I am happy with how I look at 35. I lost about 40 pounds in the last year. The general effect has been good (I'm a size 4 now at 5'7"), I started to notice a more pronounced nasojugal groove in my upper cheeks. Admittedly, what I have is very mild, but I'm too young for groves in my face. I have no other wrinkles. I have read extensively on this site, and there seem to be different recommendations for handling this. What is least costly and least risky? Juvederm? I'd be grateful for your advice.
