Yes, I was blessed with good lashes, but I still use a lash serum. This one is prostaglandin free. I haven't been consistently using it twice a day, and it takes a few months to see results, but it works! There is a brow and lash formula. They are both the same formulation! You can use the brow one on your lashes; @goalstogetglowing recommends doing that as it is easier to apply. LTKBeauty
