Straight men are such pathetic creeps. Perverts that would jizz over a girls forehead.
Norman! What did you put in my tea?

So you notice the forehead? Weird.
The first thing I notice is the eyebrows, which makes much more sense. Bad eyebrows will ruin any look, great foreheads included.

Because she's younger. But after 30 she'd look better with it; the natural expressions won't look "adorable" anymore.
Mitch Grassi of Pentatonix, freshly Botoxed in the "My Favourite Things" video. I know it's fresh because his eyebrows don't move in this video.
Compare 7 years prior, when PTX was first starting out. No Botox Mitch Grassi, and you can see his expression lines. If he left these unchecked, the 7 years would have not been as kind to him.

This is her smile BEFORE Botox, an older picture: Note the eye size is smaller than the above pic, the crow's feet, and the natural puffiness on the bottom from smiling.

I'm not saying she hasn't had botox but I'm not sure why she'd need it. Makeup and filters can often achieve the look that you're attributing to botox.

She looks young enough to not need it
