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.

Amazing Product!!
Where do I start? I can't say enough about this product!!! First of all the seller is a small family owned business and their service is amazing. If you have any questions or concerns they will get back to you within 24 hours. The delivery also was great. It was fast and the package came completely in tact. This product works! You must use it as instructed. Twice a day...first thing in the morning after washing your face and before bed. Then you can apply your make-up after the serum dries. My lashes are very long and thick now. It seemed to happen all of a sudden after consistent use. The serum is quite runny, but don't let that discourage you or think that it won't work. After dipping the wand in the tube you will have a few drops of the liquid on the wand. I found the best way was to lay the wand with the drops on it on my eyelash base. Then I worked it in with the brush on the end of the wand. It seems complicated, but it isn't. It will work even if you think that you are not doing it perfectly. The other thing that I like is it does not irritate my eyes. I used to use another product that was 4 Xs the price and it made my eyes dry and itchy. NYK1 Lash Growth did not irritate my eyes. Another surprising fact is this product works on older women. I am in my mid 60s. Everything starts to fall apart after a certain age and my eyelashes had become short and almost non-existent. Now they are long and my eyes looks so pretty. My husband is constantly commenting on how much he likes them. As I mentioned earlier, the serum is quite runny so be careful to keep the tube upright while you are applying it to the base of your eyelashes. I was careless and turned the tube upside down and a lot of the liquid spilled out onto my bathroom floor. I thought that I would not have enough left to see results. But I did! It seems like a small amount in the tube, but there really is enough of the product in your first tube to see amazing results. I just re-ordered my second tube because I am now maintaining my long eyelashes by applying it 2-3 days a week and only once a day at bedtime. If you are considering the different eyelash growth products, I am whole-heartedly recommending this one before you try any other.

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.

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

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.

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.

J’utilise ce sérum depuis plus de deux ans.. très bons résultats ..? Recommande ce sérum pour la repousse des sourcils

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
