Great alternative to prostaglandin serums
I forced myself to stop using grand lash, it works yes. But it also was making my lashline very dark, my eyes red, my lashs were long but very thin. I forst transitioned to dime beauty using the ordinary lash serum at the same time. Usually when I stop using grand lash, fhe fall out of lashes follows quickly and then the regrowth is very very slow. And my lashes never get long, they'll stay short. Dime caused some serious eye burninh and i returned it. I picked up this one to try and I'm really impressed. Its been a month of using this and my lashes are long like as if I'm still using grand lash. My lashes are also more plentiful, I have a very full lash line and the lashes are not thin. I also deal with autoimmune issues that cause hair loss and that happens with my lashes as well. I'm really impressed to be off grand lash for 2 months and to still have lashes. I think this serum is working and I enjoy the way it feels on my lashline. I'll keep using this and update later if anything changes.
🗑️ is where this belongs
My aesthetician told me I needed to switch off prostaglandin from Rodan and Fields because it was darkening under my eyes. So this was one of the options on the website she gave me. This stuff is garbage. My eyelashes have never been so short in the last 10 years With a crust in the morning.
