Hi Allice. There are no negative information about that product. While using it, you can be able to lenghten your eyelashes in a certain amount of time, let's say, 2 or 3 months. However, keep in mind this product may not produce the same effect in everybody's eyelashes in a time period you wish to get longing results. As every product, consistency is the key; if you want to see results it takes time.
Also, stop using it if you have an allergic reaction. Sorry that we can't see your full post as sharing links is forbidden. But I could suggest to check for more inputs from current users so then take your own actions.
And again, any redness or itchy skin rash while using it, stop immediately. Something health is highly important than vanity...
