“Latisse After Upper Bleph - Southern California”

Hi ladies, I had an upper bleph (along with a faclift) 4 months ago. The lashes got a little thin after the surgery so I decided to try latisse after scars healed. Just finished week one and my eyelids are pink! Is this normal? I apply the latisse one drop per eye with a very fine eyeliner brush. Eyes get pretty itchy right after but by morning are OK. Just wondering if this is normal and does it get better. The first few days my eyes got pretty red too but that has stopped. I am blessed with pretty thick lashes naturally but want to fill in where the surgery thinned them out. (not sure why that happened as the scar is nowhere near the lash line.)
