This is my first time getting forehead fillers, please give me some advice.

Lately, whenever I look in the mirror, my forehead looks a bit sunken and lacks dimension, so I am considering forehead fillers. Rather than an overly convex or unnatural change, I want a natural improvement that fits the overall look of my face. Since this is my first time getting forehead fillers, I am worried about pain, bruising, and swelling, and I am also wondering if I can return to my daily life immediately after the procedure. I would like to know how satisfied those who have actually received the treatment were, and whether the filler spread or the shape changed over time. I am also curious about how best to convey the image or forehead shape I want during the consultation. Please share any experiences or tips you recommend from those who were satisfied with a natural forehead line, as well as any advantages.
