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.

Superb Service and so Easy to Use
I received this LashForce serum in a high end packing which was really nice. The item arrived quickly and was well protected. The product is easy to use with a really well made brush used to apply the serum. Seems good value for money as one can pay a lot more for a lot less serum. Right now I cannot say how well it has worked and I will try to update my review in a few months time if I can see a difference. It is important to remember to apply twice a day to clean eyes. Setting a reminder on my phone helps me to remember. I was sent a good video by the seller which shows you how to apply the serum in an effective way. Overall score of 4 stars is because I don't know what the results will be.

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.

Impressed!
I have been very impressed with this. Granted I had quite good lashes in my younger years but not so much recently. I bought it because for a few weeks I would extensions and they ruined a lot of my lashes, pulled them out or broke them. This serum has brought them back longer and thicker than ever! I’ve had my bottle since March and it’s now June, I probably need to start thinking about a new tube but seems to last a while- although I didn’t always use it twice a day, maybe in the beginning but now it tends to be an evening “maintaining” thing. Super easy to use. Recommend to everyone. Often getting asked if I have mascara on or if they’re fake. Will upload a photo if I remember. I dyed my lashes and with this new length they look great! Definitely worked for me! Will be buying my second tube shortly.

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.

Oh Mio Dio.
Partiamo dal fatto che le mie sopracciglia da metà arcata fino alla punta erano quasi rase (di natura). Scrivo questa recensione forse preventivamente visto che non sono passati 3 mesi, ma l'adoro. Le sopracciglia già ora, a un mese e mezzo di distanza più o meno, sono molto più piene, l'effetto raso è sparito e l'ho usato come scritto nelle indicazioni, quindi mattina e sera, con le sopracciglia umide. Io l'ho usato in questo modo, cioè mettendo dell'acqua micellare molto delicata su un dichetto, l'ho passato delicatamente sulle sopracciglia senza spettinarle troppo e pochissimo dopo il siero. Mi sono concentrata sulla parte che più mi interessa, e solo una piccola passata all'inizio per essere uniforme ma sono davvero belle ora. A volte prude un po' ma nulla di grave. Però attenzione, io l'ho usato solo sulle sopracciglia, non so se funziona anche per le ciglia ma sconsiglierei dato questo prurito occasionale. Comunque super promosso
