As I age, my skin elasticity is decreasing, causing my facial contours to sag. Since I have no fullness in my cheeks, I'm afraid that if I get the procedure done incorrectly, I might end up with a skeletal face. I've heard that radio frequency and ultrasound carry a risk of causing cheek hollowing, so I'm leaning toward On-Da Lifting, which is said to allow for precise fat targeting. I'm considering getting a consultation because it allows for collagen tightening only in the areas I want. I'm already excited and nervous. I'm curious how long the improved elasticity typically lasts after the procedure, and if it's effective after just one session. If anyone has successfully filled their cheeks with firm elasticity using On-Da Lifting without any hollowing, please share your experience.
