Best working product so far
I have tried other brands, but this one is my favorite. It might be a bit pricier but it's worth it. So easy to apply. Not sticky and not clumpy. After 2 weeks the difference is clear. No need for false lashes as mascara will show of the thickness of your lashes easier and enhance the length too. I will buy this again. It does what it says on the pack.

WORKS GREAT. MORE PRODUCT, NO PAIN
I Love this. I just ordered the brow formula. I find the application process so easy. I love that you get so much product. My eyelashes are coarse. I like when the formula gets on the lashes. It seems to thicken them. I have used Revitalash, which works well, but is $110 and the tube dries out quickly. Same with the brow formula. I saw this and thought if it works, it would be so cost effective. I switched every other day until the revitalash ran out. Well the NYK1 works as well. I’ll write a review on the brow serum after giving it a chance. Ps. I also tint my own lashes black which makes them look crazy noticeable and long. I recommended Aryana lash tint. (Also can be bought at Amazon) It is vegan, but I have accidentally got some in my eye and it hurts. Rinses out easily, but does sting. The best part, after you get used to it, you can tint them beautifully yourself. I had this done professionally and this product looks better and lasts longer. (sometimes 2 months) I recommend the 2 together….. serum and tint. What a difference! And no mascara necessary. EVER

Seems to be working….
I have Hashimotos Thyroid and have battled hair & lash fallout for 3 decades. That’s right, 30 years. At first the Dr prescribed Lattese which made my eyes constantly red, but grew lashes so long that they banged uncomfortably into my sunglasses. Since I didn’t like the idea (or cost) of using a chemical on my eyes, I switched to Grande Lash MD. It was less $$ than lattese and worked pretty well, at least for the first 6 months. It seemed to be working less well as the months went by so I began trying other brands of herbal type lash serums but none worked hardly at all. I almost didn’t order this one - it just seemed too inexpensive - but I was more than tired of shelling out buckets of $$ for lash serums. So I gave it a go. Here’s what’s different from other brands: Big tube with plenty of product They instruct you to use twice daily: am & pm. They tell you to massage it into the base of your lashes. While I’d rather it wasn’t made in China, it seems to be a safe product. I’ve had zero irritation or stinging - even when accidentally getting it into my eye. I stopped using my Grande Lash & started using this. Within a week I began seeing extra length on my lashes. By the second week my lashes were noticeably thicker - meaning there were more lashes growing - not that they were becoming more coarse. And last night (about a month of use) 2 friends both commented on how long & lush my eyelashes looked. So I will definitely be ordering again.

ZONT ZO IT, ZONT ZO IT GURL
I ordered this product because of the recent positive reviews. My eye curler cut out a good chunk of my eyelashes because I used a cheap one (Btw I HIGHLY recommend the Shiseido eyelash curler. I KNOW I KNOW It is pricey, but please don't cheap out. Dont let this happen to you !! ) and my confidence went down so lash serum was the option for me. Many were on the market, but all others led me here, and the price is medium it's not cheap like 10 + but it is not expensive, like 86+ it was medium so it was with the positive reviews, I WAS SOLD. I was so excited to start; it came in cute packaging and felt expensive for a lash serum. The smell was ew, but I brushed it off because I was finally going to grow my lashes back !! I used it only during the night and always on the lash line or above (NEVER ON THE EYE). On my 1st day it went well. It was nothing bad I just woke up with a lil blurry vision; that WAS NOT NORMAL LMAO, but again, i brushed it off. By the 4th day, i only woke up to slightly red eyes but i brushed it off because i desperately wanted my lashes back. During this period my eyes had gotten very sensitive with the sun, and headaches. I dont get headaches and my eyes were never sensitive. On the fifth day, I woke up as if I had been crying all night, SO RED it stung closing my eyes too. I STOPPED. I didn't last a week with this product, I really wanted it to work, but I couldn't keep hurting myself even if I really wanted lashes, NOT WORTH IT. Thankfully I was able to return it, it's been a while now, but what I have noticed is that my lashes have been falling off a bit I know it's because of this product, but apparently, it is normal because I did go against my natural growth, SO BEWARE with that. In conclusion, if you have sensitive eyes, DO NOT USE THIS PRODUCT!! And if you notice redness, stop, girl ZONT BE LIKE ME. I wouldn't recommend this product, but again THIS IS MY EXPERIENCE !! everyone is different and works for some people but it's not for me.

Helped my fading eyelashes
I recently started using a lash growth serum, and I'm absolutely amazed by the results! This serum has completely transformed my lashes, making them longer, thicker, and more voluminous than ever before. I love how easy it is to incorporate into my daily beauty routine – just a quick swipe along the lash line before bed, and I'm done! The formula is gentle and non-irritating, so I can use it with confidence, knowing that it won't cause any adverse reactions. Plus, the results are truly incredible – within just a few weeks of consistent use, I noticed a significant improvement in the length and density of my lashes. Since incorporating this lash growth serum into my routine, I've received countless compliments on my lashes, and I feel more confident than ever batting my eyes. Whether you're looking to enhance your natural lashes or recover from damage caused by extensions or harsh mascaras, I highly recommend giving this lash growth serum a try – it's a game-changer for anyone looking to achieve longer, fuller lashes!

Effectiveness
I've always had short lashes and kept using lash extensions so I get more confident with my eye look. I always envied my friends who have long natural lashes so I want to try and have one since I am tired of getting my eyelashes fall off due to lash extensions. A friend of mine recommended this lash growth serum that she was using LashForce. At first I was getting impatient and hesitant as I haven't seen any results within the first 1st week but my friend told me to just keep applying it everyday day and night and give it more time. Then, on the 3rd week I saw my lashes getting darker and longer especially on the lower lashes as they are very short. It definitely worked! I am so happy that I now have those long natural lashes that some celebrities have! Now I have been using this product for 3 months now and haven't used lash extensions since. This one works well with a Lash Lift too!

Works!!!
I been using this serum for almost two months now, with some days twice daily and some days once daily. Im shocked. Now disclaimer: I naturally have long and thick eyelashes, but I never could achieve that falsie look with mascara alone. I figured, "why the hell not?" with trying this product. I also do not suffer from any conditions that would affect my eyelash growth. In any case, the stuff in this tube is crack. My eyelashes are INSANE NOW. I have achieved what can be close to a falsie look with only mascara. If I want to be deceitful, I could color in my top waterline with a black eyeliner pencil to enhance the look, but why bother?! I am just so shocked this stuff works. Now, as far as side effects: for me personally, I do get a bit of itchiness on my eyelash line as time passes. No pain, no burning, no discoloration. It's overall very mild. I would imagine that is because the hair follicles are growing (kinda like how our pubes itch after a few days later from shaving?) In any case, I would give this a real try! Please do a patch test before applying this to your eye lashes just in case you get a more sever reaction. And if the icthiness gets worse for you and there is any discoloration (a sign of irritation), please return this product. Amazon makes returns easy, so there is not much to lose with trying this out. Good luck!!
