Eyelash Enhancing Serum with HEXATEIN 1 Complex – Lash Serum for Eyelashes Conditioning & Hydrating – Longer-Looking, Fuller and Thicker Appearing Lashes – 3 mL / 0.1 fl oz

It WORKS! Within 2 weeks I noticed a difference, within 4-6 weeks my lashes were noticeably longer and I didn’t need to wear so much mascara. I get sooo many compliments on my lashes 🥹. It also doesn’t sting your eye too much if some gets in it, and doesn’t have a scent. One tube lasts sooo long, I’ve had mine almost 8 months so far and use it consistently.I typically will apply it for 6-8 weeks at a time, take a break for a month, and then reapply again. Otherwise my lashes get TOO long 🤣 ALSO, there haven’t been any changes in my eye colour or orbital fat which can happen with some other lash serums. So happy!!

Why did you pick this product vs others?:I’ve used it for 2 weeks so far. I have seen a noticeable difference but it’s only been 2 weeks. I use Rapid Lash at night. I also use the E.L.F lash serum twice a day along with it. I’m happy with my results so far so I’ll continue to use it. It doesn’t burn or make my eyes/eyelids itchy or irritated. The price is also really affordable. UPDATE:The 3 photo picture is before the serum, 2 weeks in and 4 weeks in. My lashes are definitely thicker, darker and fuller after 4 weeks.Buy the serum!!!

I've tried this product once in Japan and the rest I've bought from Amazon. Genuinely great product. I used to have really long lashes but ever since I wore lash clusters they've fallen out. Now my lashes are getting pretty thick and long again. It does sting a little when you put it on but it's not unbearable. I will say it gets a little frustrating when some of the product slips into the little stopper. Plus it's not even that expensive compared to babe lash or granelash serums. I just wish there were more product!(First photo before, second photo after a year)

I've bought this product before and like it. And it doesn't contain Propylene Glycole - A BIG plus.

This stuff truly works for me. My lashes are noticeably longer. I’ve read about lash serums leading to discoloration but I’ve been using this for about 3 years now and I’ve never had the problem.

I didn't give my lashes a vacay from extensions and noticed that I had lost quite a few. RapidLash has been a savior - I immediately saw results after several days of use (been using the product for almost a month now. I see faster growth, but I have yet to see increase in density or thickness). However, I am one of the unlucky that suffered side effects: darkening of skin around the eye area, worsening of dark circles. Makeup helps, but I just stopped using the product for a couple of days and some of the side effects went away. Not sure if I can justify the cost for continued use, but hopefully there will come a day when I don't need to use this product any longer.

I usually get lash serum MD. It works so much better than this. My lashes did not grow that fast or that long with this serum. I was disappointed. Maybe you will have better results.

I'm in my fourth week of using this serum. Within 2 weeks, I saw lengthening, thickening, and some new hairs. I used it about 3-5 times a week. It was noticeable by the second week but definitely visible in my brow areas by the third week. Almost overnight, places I thought would remain bare forever, suddenly had brow hairs again. My eyebrows were already full but overnight in the third week, they were long and bushy so I could shape them without having to draw in the bare areas.I didn't see any difference in my lower lashes or in the density of my upper lashes. However, the lashes that were already present seem thicker (healthier?) There was mostly just a lengthening effect (about 1 mm) and a few new lashes but not necessarily where I wanted them.The bad - skin where the serum got on gave me panda eyes since this contains cloprostenate. There is noticeable skin darkening after the first week as the product started working. I am very pale and it now looks like I have dark circles because the serum got onto my undereye whenever I blinked after application. There are also dark streaks of pigmented discoloration in the fine lines of my upper eyelids above the lashline. My usual eye makeup definitely does not look like it use to without color corrector or concealer since the skin pigmentation affects the undertones of the makeup. I was expecting any darkening effect would help with the look of density along the tightline but it just spread everywhere the serum touched. It might not be a problem if the brow area darkens a bit but I am definitely not happy with the panda eyes. I am a cool neutral tone and the skin around my eyes now have all colors of a fresh bruise.There is not much lash fallout - just a few here and there. It started during the third week but growth was more than any fallout.
