Have just started using so not sure on results as of yet. On a positive note have been using over my cluster lashes also and it has not effect on them at all which is a bonus
not sure if it worked or if time was the answer but i ripped half my lashes out wish my curler and sure enough they're pretty much grown back after about 4 weeks
My lashes and brows are fuller and thicker. Thos I a must have.
It all round looks good and goes on easily but it will take a couple of months to see if it actually helps or not. There is no smell and I had no negative skin reaction.
Great serum
