For nasolabial folds, how many shots of Density High are needed for the procedure to show noticeable results?

Lately, I feel so depressed because whenever I smile, the sagging around my nasolabial folds looks deeper, and my whole face feels like it has lost all its elasticity. I can't even bring myself to try Ultherapy because I heard it's too painful, so I've been searching for reviews of Density High for a week now, as it is said to be less painful and provide effective lifting!

I'm drawn to it because it claims to improve both elasticity and texture at once, but I'm not sure how many shots I should choose to get the proper results from Density High... The price is also quite steep, so I can't bring myself to open the payment page.

Are there any ladies out there who have paid for Density High with their own money? How many shots did you get, and can you really see the lines getting tighter and lifted right after the procedure?
