Great product
Second time ordering this product. It works really well and was recommended by a friend definitely worth the money and last ages

Very noticeable improvement!
Genuinely didn’t expect much out of this stuff, but I’m happy to be proved wrong! It’s very thin almost like water. Read the instructions and have been applying religiously morning and night for a month ‘drenched not dripping’ to quote the directions. My short stubby eyelashes are noticeably longer, and seem to have thickened up. Will definitely continue with it I’m impressed so far.

Eye lash serum
Excellent product I could definitely tell the difference after 6 months on my second one now

Lash serum
I’ve used many lash serums before and found this to be one of the most effective for gaining length and thickness. However, the large tube is a mixed blessing. With the serum lasting for longer, several months indeed, I suspect that there’s a risk of bacteria getting in there. As some other reviewers have noticed, about three months into the tube I started noticing a slight soreness after use, and small red patches at the outside edge of the lower lash line. I gave it a rest, and found that my longer lashes lasted a good two months, which is fantastic. In conclusion, this is an effective product, but I’ve decided to return to serums in a smaller tube, as I think they’re more hygienic.

No longer works
This used to be great but I think they must have changed the formula. The latest bottle I purchased has not worked at all, it also stings my eyes which the other bottles did not. I will not buy this again.

Lashes are thicker, longer and softer - brilliant!
Bought this at the end of September and have left it until now to review to see how it works. The results are excellent! My lashes are thicker, longer and softer. Would totally recommend this product.

Effective but caveat
I was looking for something that wouldn't cause darkness around my eyes or lids. It's effective for lash growth but my eyes definitely have dark red/brown pigmentation now despite using it once a day

Absolutely incredible and works like a charm
I've been using this product since the start of may. Top photo was taken May 3rd, bottom one taken on July 22nd. I had the tiniest bit of irritation when I started however it wasn't even noticeable. I saw a difference already at week 4/5, and at week 8 other people started to notice too. The claims are all true: it makes your lashes, thicker, longer and darker. I'm not wearing mascara in either of those photos. The application is super easy. Just make sure you stay consistent and within a few weeks you'll see a difference too. The serum lasts a while and although a bit pricey it is definitely worth every penny. My lashes have never looked better!
