I hate to say I need it, but I do
I’ve only used this for 1 month. I use it once a day (at night). I’ve had eyelash extensions for over 3 years. So when I decided to let go, my natural lashes were short and stubby, and spaced out. The first picture I had been using the serum for a week already (didn’t take before photos because I didn’t expect it to work at all). But even at ONE week of use, I started to see a difference. The first photo I also still have some of my classic extensions in + mascara. The other pictures are 100% makeup free, and just results! I will continue to purchase this 4ever.

WORTH EVERY PENNY
Ok I’m usually not one to write reviews, but I genuinely had to for this one. I had eyelash extensions for over 5 years, and once I finally removed them, my natural lashes were extremely damaged, short, sparse, and honestly pretty fragile. I originally started using Show Lash Serum and it worked AMAZING for about a year, but eventually my lashes seemed to get used to the formula and I stopped seeing much growth. I started using GrandeLASH on April 21st, and it’s now May 23rd… and the difference is honestly insane. I truly did not expect it to work this well, especially this fast. In my before photo, my lashes were short, separated, and I even had a noticeable gap. Now my lashes look fuller, longer, darker, and so much healthier overall. The gap is completely gone and they no longer look weak or brittle. The craziest part is this transformation happened in only about a month. I’m honestly shocked every time I look at old pictures. This product is 100% worth the money and I will absolutely keep repurchasing.

Visible results! Significant growth and length for the whole family.
I purchased this GrandeLASH-MD Lash Enhancing Serum for my daughters and myself, and we are all beyond impressed with the results. If you are looking for a serum that actually delivers on its promises, this is the one.Why we love this serum:Proven Results: We have all seen significant growth and noticeable length in our eyelashes since we started using it. It really works!Easy to Use: The application is quick and fits perfectly into our nightly routines.Great for Sensitive Eyes: None of us have experienced any irritation, which was a priority for me when sharing it with my girls.High-Quality Formula: You can tell this is a premium, vitamin-infused product that actually nourishes the lashes.It’s rare to find a beauty product that works consistently for everyone, but this serum has definitely earned a permanent spot on our vanity. Highly recommend!

Wow , it actually works. 4 week results.
I am hopping on the review trains because this stuff actually works . lol I made sure I checked all my receipts but this has been 4 weeks since I started using it and I can confidently say my lashes are in fact longer . I paired some castor oil with this serum and I’m really proud of these results .my lashes are naturally super thin so I was surprised this made a difference , but I’m going to continue to use this and see what it can do for me . So I’ll check back in another 90 days lol .

Great sustained results 18 months later!
I’ve been using this serum for the past 18months or so and have definitely noticed sustained and noticeable results! I have naturally very short, straight Asian lashes- and under monolid eyes they look even shorter and straighter from the weight of the lid. They were so short that I literally had a (admittedly clueless) friend ask me if I even had eyelashes when I was younger. Ouch. I use this serum twice a day everyday, and I’ve sustained longer lashes with a surprising curl to them! Enough that my mom and optometrist both separately noticed how long they’ve gotten over the last year or two! I was worried it would “lose its effect” if I didn’t switch up the formulas but my 6 month supply still has some in the tube about 1.5 years later and they’ve stayed long and curled much to my delight! I don’t look like I have falsies on or anything dramatic, but for my super stubby lashes, I look like I have full normal lashes now! I’m super happy with the results, and with some mascara, they’re very noticeable! But the photos I included are bare lashes. I don’t have any before photos, but I included a photo of someone else’s lashes which are basically how straight and short mine were. Except mine were honestly shorter and sparser than the photo. Im also a contacts wearer and I’ve never had an issue with the formula in terms of bothering my eyes or eyelids- that said, if you layer it with an eye cream it might burn a little? But that could be the formulas interacting badly, I just make sure my eye cream is absorbed and dry before I put the lash serum on and I’ve never had issues. I apply it in the morning when I’m getting ready for the day, let it dry, then put on my makeup like normal, and at night at the end of my skincare once my skincare is dry.
