Hyalogic Lush Lash and Brow Serum

I bought this for my brows, not my lashes, as a cheaper alternative to another more expensive serum which I liked, Prevage. The Prevage was five times more expensive and while it didn’t totally regrow my sparse over plucked brows, it definitely made them look thicker and healthier. The Hyalogic serum is all right, but it doesn’t give me anywhere the same results as Prevage.
