I'm not sure if it's okay to get Botox when my wrinkles aren't very visible.

Lately, when I take photos, I’ve started to see small fine lines between my eyebrows and around my eyes when I smile.

I don't usually pay much attention to it, but it really stands out in photos.
I wonder if there are people who get Botox in advance for times like this.

My wrinkles aren't deep yet, so I'm worried that getting the procedure done right away might be a waste.
