Been trying this for 3 weeks now. I don't wear mascara so was hoping this might define my lashes in some way. It doesn't & I don't think it conditions my lashes either. As a tonic it does nothing but maybe it works as an eyelash primer.

I do think my eyelashes were a bit softer and generally healthier than they were before use of this product, however I can't say I saw any drastic changes in the month or two in length or thickness I used this. I think since it goes on the lashes themselves, which are already dead matter, its more of measure to perhaps stop too much mascara usage drying and breaking your lashes. Other more effective products I've used target the lash root instead.

Eyelashes appear thicker and longer when used and less eyelash loss since the beginning of use.

Caused me no eye irritation compared to other products.

I accidentally ripped half my lashes out and they’re fully grown back I only used this serum a few times a day! I will be repurchasing!!

I get eyelash extensions continually and noticed my own lash hair was looking bare. I got this to use whilst taking a break been using two weeks and can notice a difference with hairs growing back in area that was sparse. Would recomend. 

I like using this type of products and I was really pleasantly surprised that this is a Japanese brand actualle (I was not familiar with it). Loved a small brush! So nice and comfortable to apply to your lashes and avoid betting the tonic into your eye.

Tried other serums which are much better. This hasn’t done anything. In fact since I’ve stopped using my other serum my eyelashes are much shorter.

I'm really quite impressed with this. I've been using it twice a day and my lashes do seem to be longer and stronger. Will definitely be buying again.
