Should I ask to reduce the dosage next time for forehead Botox?

This was my first time getting forehead Botox, and I really like how my wrinkles have decreased. Even when I open my eyes wide, horizontal lines don't appear as prominently on my forehead as they used to, so I feel less self-conscious when taking photos.

However, there was one thing I hadn't expected. As the movement of my forehead decreased, the shape of my eyebrows changed slightly, and I felt like my impression was sharper and looked angry than before.

It’s not severely awkward, but I actually prefer natural facial expressions, so I’d like to reduce this a bit the next time I get hit.

So, I'm curious, for those who experienced this kind of change in appearance when they first got forehead Botox, when about the next treatment... Would you like to request a reduction in volume or a slightly different injection site?

I am wondering if my facial expressions return to their original state after the effects of Botox wear off, or if it would be better to get a slightly weaker dose from the start next time.

I definitely want to reduce wrinkles, but I want to avoid eyebrow sagging or changes to my overall appearance as much as possible. I am curious about the experiences of those who have actually undergone the procedure.
