I bought the serum because I have patchy eyebrows. I have used it every night for about 8 weeks now and have definitely noticed a difference. It took a while, I have probably only really started to notice the changes over the past week or so, but my brows look fuller and darker. So bear with it and be consistent.I still have the patches (they are mostly towards the start of my brows, near the top of the nose) but they don't look as visible, probably because the hair around them is covering them more as it grows. I will continue to use the serum and will also repurchase when it runs out!I am 46 - just in case anyone thinks it won't work for them because of their age or anything!
