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.

It definitely works - For me the results showed after 5 weeks use
There is no doubt at all that this eyelash serum works. My lashes are significantly longer but don't expect immediate results, as it took 5 to 6 weeks to see much longer lashes. Good points are :- - Easy to apply - it is quite watery but that makes it easier for it to soak in. - The size of the NYK1 serum is almost double the ml that you get with some other serums, so the value compared to those is good. - The company themselves answer any query you ask promptly and are reliable and reasonable. - My latest NYK1 serum doesn't sting my eyes if it accidentally goes in them, whereas I my last NYK1 serum really stung my eyes. So I'm confused as to why it is different. - the results are noticeable in around 5 weeks and even more noticeable after 6 -8 weeks. - People who know you will ask if your lashes are real or false as they become noticeably longer. The not so good points :- - Your eyes may react to the serum, a stinging feeling and reddened eyes. - After about 8 weeks some of your lashes naturally fall out as they are at the end of their life cycle. This can lead to your lashes looking a bit sparse in places. Some very short and some very long. It then takes a few weeks for them to even out again. - As the serum becomes older I think it makes your eyes sting more than when it's newly opened. - Soon after you stop using it your eyelashes go back to their usual shorter length, meaning that it is a lifetime commitment, which is expensive. All in all though if you want longer lashes for a big occasion then use this at least 6 weeks before that day and you are virtually guaranteed longer lashes. I'm not sure I will continue using this forever but it's lovely to know that it actually works as I've tried at least 3 other cheaper eyelash serums which definitely do not work.

Lash growth at expense of eyelid health
I decided to give NYK1 another try having previously used it in 2021 but stopped use as it seemed to be causing blocked oil glands and problems with styes. I thought I would try it again as it had helped lash growth so retried it at the start of this year. However, I developed a horrible eyelid infection with swelling and an infected stye (having had no issues with styes at all over the intervening years) resulting in antibiotics and now a hard lump (chalazion) on one of my eyelids after several weeks. This has confirmed for me that I need to avoid this product as it has clearly contributed to these eyelid issues. It's a shame as it does seem to add lash length but not worth the cost health wise.

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.
