I tried this as I had been using another lash serum for the past couple of years and thought I'd give this a go as a change.
The packaging on this is laughably bad. The applicator is enormous - far too large for your lash line and when you twist the base the product comes out in massive blobs or nothing at all. Loreal make many liquid eyeliners I don't know why they didn't copy the packaging of one of these. I've been using this for about 4 weeks now and my lashes are shorter than they have been in years (which means they are returning to their normal length as I had been using another lash product). Don't do it.
Worked for me... kind of. Strong and thick lashes as a result but longer? No So I'm very on the fence with this product
