Are the characteristics of forehead fillers significantly different from fillers in other areas?

I've never had fillers before, so I'm curious about the characteristics of forehead fillers first, haha.

I’ve heard reviews about lip and chin fillers from people around me, but since forehead fillers seem to naturally fill in a relatively large area, I thought the procedure might be a bit different.

I understand that forehead fillers aren't just about filling in sunken areas, but rather a procedure that considers the overall curve of the forehead. Is that correct?

In that case, rather than designing based on just one part, I think it is important to consider the front view, the side view, and the overall facial proportions together.

I am wondering if creating a natural curve is particularly important among the features of forehead fillers.

For me, the most important thing is that the boundary isn't noticeable and it looks like my natural forehead, rather than the volume itself.

Also, is it possible to feel forehead fillers hard or experience a foreign body sensation when touching them immediately after the procedure?

I wonder if that feeling becomes natural over time.

Also, I would like to know if many people avoid sleeping on their stomach or pressing hard on their forehead for the first few days due to the shape.

I feel like even wearing something like a hat might be a bit of a burden, so I'm 괜히 worried about it haha.

If you properly understand the characteristics of forehead fillers, I think you can worry less after the procedure.

For those who actually received it, were there parts that were simpler than expected, and things you wish you had known in advance?

I'm also curious about the experiences of those who started with forehead fillers for their first filler treatment haha.
