The lash serum is a very good product. After using it for around a month you can really start seeing the results. However the serum works only for around 2-3 months because after that your lashes often have refreshed and you need to apply the serum again. It is a very good product but you need to be careful with applying when having a sensitive skin and only but it on the lashes and not on your skin. This is because it can cause sometimes a little rash or irritation around the eye. 

Im completely unhappy with the brand. My review is not about this profuct but about the brand. I have been doing lash lifting for years.Im not a newbie and did everything like in instructions. The pads are terribly inflexible that one side always sticks out, they dont stick well also because the glue is terrible. Before, I used another brand (which is much better then this because it is actually usable) and thought I can support this brand since it looked like it was based in NL but it came from New York(?). On top of it all they don't even respond to my emails that I have sent to support team. Scamming does not necessarily entail not sending a product or, it can also be playing deaf to unhappy customers.

I'm not gonna lie: I was so sceptical when I bought it, but I needed to boost my eyelashes a bit and I got tired of mascara's that didn't really do it for me. I've been using this for a long time now, and it really works! My eyelashes look gorgeous. I almost don't even need to apply mascara!

I got this product the first time from my beautician after I had a lashlift. And I must say it is absolutely fantastic. My eyelashes are short and very straight. After using this for 3 months my lashes are thicker and lo get then ever. You just use it at night after cleaning your face and that's it

I use this product since 2019 and I never found anything better. My lashes are usually not very long so this serum is a lifesaver. I forgot how to use mascara because I don’t need it anymore! This product made my lashes very long and curly and it’s so easy to use! I just apply it once before going to bed. Once I got to use it, I saw the first results in a few days already. Surely recommend it to every each of you!

Works like a charm makes you're lashes 10 times bigger I definitely recommend it's my holy grail istg

I've been using this serum for like 15 days and I am impressed. I have used maaany of them. This one in 15 days already made my eyelashes longer and curlier!! Can't wait to see the progress in a month!

Have been using this for three months but haven’t seen much improvement despite using it daily :( I’ve tried other and cheaper brands that worked better.

I use this every night before bed and oh my...it makes my lash look so much stronger, longer and fluffier. It has no fragrances, which is a plus. It's also pretty cheap, you can find it at Hema. It’s a must for me

Even though my favorite is the uklash serum this one is amazing too. It does deliver what it promises, did not cause irritation and I'd definitely use it again! The only problem is the price! It's not affordable for many of us. So, I'd definitely recommend it, if one can pay this amount, but since other serums work too I wouldn't sweat it if it wasn't in my budget!

I have used this product for some months now. Previously I had only used another much more expensive brand. But I thought I might as well give it a try. It ended up being truly amazing. My eyelashes were sparse, thin and would fall easily. After using this they look great! Very long, pretty thick and strong. It did not cause any irritation (mind you I have sensitive eyes and allergies), it does not have any smell and it lasted for months. Plus it's one of the most affordable out there!

With about 2 weeks of use, you will already see immediate results on your lashes. Longer and fuller lashes. The only disadvantage is, therefore, when you stop using the product, growth decreases and new lashes grow back briefly. Recommended to use it with breaks.

This serum seriously gives me longer lashes in a week. Much stronger, less likely to break down. It is easy to apply with an eyeliner function. It is very affordable and can be bought at a grocery store. Every night after taking off my makeup, I put it on. #biovene #lashserum

Since I started using this eyelash serum consistently every night, my lashes have become much fuller and longer! I didn't expect it, but after a month, I really saw a clear difference. I need a lot less mascara, and I definitely don't need that eyelash curler anymore! Highly recommended, it does what it promises!

I applied this serum every day before going to bed for 4 weeks. Apply thinly to the eyelash base. No irritation. I really have longer, fuller and thicker lashes, really great! The package insert states that you should apply the serum 2 to 3 times after 4 weeks of use to achieve your results. I'm now at the end of my 4 weeks, so I haven't been able to do any maintenance yet. I absolutely recommend this, you will be amazed at the result. #AugustFavourite #WeAreEves

I've been using this serum for over a year now and I'm really a fan. I do it about once or twice a week over my lashes and my lashes have become really long and strong! So price-quality ratio is also great, because such a bottle lasts a long time. I recommend it to everyone!

I've been using Nanolash's eyelash serum for 1.5 years now and I have the idea that the skin under my eyes is getting darker as a result. Are there more people who are affected by this?

I've been using it for a few weeks now, and I notice that my lashes have grown a bit! They also look a bit fuller now. It just takes a while before you really see results, but at least it works! I also tried other brands that gave me no results. (My lashes are not curled in the video so it makes them look shorter) #VIDEOSQUAD

I've been using nanolash for about 3 years now. I recently found out that when there is an ingredient on the list of an eyelash serum that includes the word “prost”, the side effects may be redness around the eyes, fat loss around the eyes (result: dark circles). I also read that your eye color may become darker. I have very red eyelids (people even think it's makeup so red/pink it is) and under my eye it's very sunken and there are always dark circles present. I'm going to switch to a serum without substances that can cause these side effects, because before using the nanolash, I had no red eyelids and no circles. So you should check with yourself whether you think the side effects are worth taking long lashes to grow because that the serum does. Also the make eyebrows grow. Personally, I don't think it's worth it. The circles and redness can be seen on the picture, including the lashes and eyebrows that have grown due to nanolash.

I've been using nanolash for 2 months and it really works. After 3 weeks, I already noticed a difference. I do have the feeling that the serum causes dark circles, because when I stop using it for a few days, the dark circles disappear. Still looking for a different serum to see what it does.
