Precautions for Improving Nasolabial Folds with Fillers?

Filler procedures have become very common, and because they are so common, I see so many people with great results and others with poor results, which makes me even more curious. Lately, when I smile, my nasolabial folds have deepened, and my dimples have merged with the wrinkles and disappeared. When I was younger, I used to hear a lot of compliments on my dimples, but now that they aren't visible, it makes me sad. So, I looked into filler procedures to get rid of my nasolabial folds, and I see that many people are satisfied. However, I've also heard that if too much is injected, the filler can shift to the cheekbones when smiling, causing them to bulge out. I have some minor concerns: how much filler should be injected to avoid that, whether the filler lines might be visible, how dangerous the location of the nasolabial folds is since blood vessels run through it, and how should I choose a clinic to minimize these risks. Also, among the famous hyaluronic acid filler brands, which ones have high satisfaction rates? If anyone has had the procedure and was satisfied, please recommend one.
