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.
I**!
Amazing stuff honestly!
I bought this because my toddler has been picking my eyelashes! It delivered on 3rd of January and been using morning and evening. I swear this stuff works! It comes with this measure and I measured 5mm and now after doing it for 4 weeks my lashes measure almost 10mm in 4 weeks! I am honestly so happy!

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.
No longer works. I have used this for years and made several purchases however, the latest batch is not doing anything. I bought 3 tubes as well to stock up which is very annoying! What has changed in the formula??

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.

Yes it worked for me!
I was very sceptical about this, but liking NYK products anyway and having lost most of my eyelashes through the menopause, i decided I had nothing to lose so I bought this. Well firstly I applied it night and morning as per the instructions, not really expecting much. I had no eye irritation with this so that was a good start. Gradually my lashes seemed to respond, grow somewhat and I at least looked like I had lashes. Not thick, long, lustrous ones but but enough to at least look reasonable. I think it helps using a good mascara that coats the lashes well. I am amazed at how much this has helped and it was worth being patient with. Other people may have better results and some not at all, but I would say give it a go and see. There is no colour to it and it dries the same as mascara. I will keep this in my save for later basket!

9 weeks later and no change unfortunately
EDIT: I have changed my review to 3 stars as after 12weeks use as instructed there is some growth in my lashes, I dont have the results some of the reviewers have had, just a bit of length but there is a slight difference. After reading the reviews and seeing the photographs of the amazing results some people have had i was excited to try this. I have used it exactly as instructed for 9 weeks now and sadly there is no change; actually there is a change my lashes are softer but as for length and volume there is no obvious change to my lashes other than being in nice condition. I have used other brands n the past and had far better results. Im so disappointed clearly it works well for some people, i dont know why its not worked for me i applied it exactly as instructed and no growth so for me its a waste of money. I have given 2 stars as there is alot of product and is easy to apply. Unfortunately it did not make a difference to my lashes so I would not recommend it.

J’utilise ce sérum depuis plus de deux ans.. très bons résultats ..? Recommande ce sérum pour la repousse des sourcils
V**A
Ça fonctionne !! Je pensais réellement encore une fois acheter un produit en espérant un miracle qui ne viendrait pas. Sans aller jusqu'au miracle, je constate une réelle repousse en tête de sourcils. Je recommanderai
