eyebrows fell off
My skin actually likes this product, but after a while, my eyebrows were thinning so i stopped using it and my eyebrows grew back. Then i tried using it again and same thing happened. I stopped again and they grew back. not worth it for me.
Love this!
Love this serum - have been using it twice a day for a while now and I like how it makes my skin feel hydrated and bright.
