That brow serum is designed to make our brows even bigger😊 I too got if from a box and as I too have have big, thick brows I would like to be a bit thinner and more elegant, I have been wondering how wise I am too use it🤔 but it has replaced or or two missing hairs😊 Only use it at night though or they might grow out of control😅
I didn't notice a massive difference if I'm honest but because I already have quite thick full brows so not sure if that's why?? I only used it on the evening as well!
