I love this product one of my holy grails for my eyelashes, They are much longer and thicker after using for a couple of months.  I would defo recommend if you are looking for a product that can both lengthen and thicken your lashes in 1 easy step. Will never not have this product in my makeup bag 

My skin is really sensitive and I would like to know how this product react is with it ? 

I was looking for a lash serum without prostaglandin analogs so I came to this serum online. Unfortunately, my eyes were uncomfortable once a day and the skin around it became irritated, red, dry and stinging. I tried to give this a twist by using it every other day, for example, and as little as possible, but unfortunately the irritation persisted to a too serious extent. I must say that in this fight, my eyelashes have become relatively longer, so it does work, but this remedy is not for me.
