I am planning to get forehead fillers, and I am curious about the duration.

Lately, my forehead looks so flat and plain that I get really stressed every time I look in the mirror. It feels stifling to have to cover it with my bangs since it's summer. I saw on the Maypure community that the reviews from people who got forehead fillers were really good and looked natural. I am seriously considering taking this opportunity to muster the courage to overcome my complex. However, since this is my first time getting any dermatological procedures, I have quite a few questions. How long does the initial shape usually last after getting forehead fillers? I know it varies by body type and lifestyle, but I would like to know the average duration I can expect. I am also worried about whether the surface might become uneven as the volume subsides over time. I would really appreciate some honest advice from those who have actually received fillers at Maypure!
