GrandeLash Transformed My Lashes in Just Four Months (2025)

One thing you need to know about me: I always need my lashes to look long, fluttery, and dramatic AF. For this reason, I’m very particular about the mascara I use, especially since my natural lashes are super light in color (#RedheadProbs). But mascara can only do so much, which is why I take extra care of my lashes by using lash conditioning and enhancing serums. Adding a lash serum to my routine has amplified my flutter and made my real lashes mimic falsies. Plus, people constantly tell me how long and healthy my lashes look—one of the best compliments ever, IMHO.

I’ve tried nearly every eyelash growth serum on the market, but none compare to the GrandeLash-MD Lash Enhancing Serum. What makes GrandeLash soooo special (besides the fact that men even see a difference...and they don’t notice anything?!)? Well, babes, you’re about to learn. Keep reading to discover everything you need to know about the GrandeLash-MD Lash Enhancing Serum, including how it works, how to use it, key ingredients, side effects, and more—and see some stunning before and after pics, of course.

What is the GrandeLash-MD Lash Enhancing Serum?

The GrandeLash-MD Lash Enhancing Serum is a powerful ophthalmologist-tested serum that improves the health of your eyelashes and enhances their volume and length. This all happens thanks to a mix of natural ingredients—including radish root extract, grape seed extract, amino acids, hyaluronic acid, honey, and aloe vera—that are rich in peptides and vitamins, which fortify and condition lashes to help them become stronger and more resilient.

Isopropyl Cloprostenate is also a key ingredient. Yes, it’s a big, hard-to-pronounce word, but it’s nothing to be afraid of. This element is a prostaglandin analog (a type of hormone) that’s also known to enhance eyelash growth (the more you know!).

When it comes to the results, most people begin to see a difference in their lashes in as little as four to six weeks. This is pretty impressive, IMO, because when using other lash serums, like Latisse, it typically takes 12 weeks to notice significant changes. (Note: GrandeLash does ultimately recommend applying their serum every day for a full 12 weeks to see the best results, so commitment is key here.)

How to use the GrandeLash-MD Lash Enhancing Serum:

Incorporating GrandeLash into your routine is easier than adding a new skincare product to your regimen—the most difficult part is simply remembering to apply it once a day. Before applying, you want to ensure your face and lashes are totally clean with no makeup remnants remaining (especially mascara, since that can hinder the effectiveness of the serum). Once your face is clean, gently swipe the applicator—which reminds me of a liquid eyeliner brush—along your upper lash line, avoiding direct contact with your eye. You don’t need to re-dip into the tube to grab more serum before applying it to your other eye. GrandeLash says that the teeny tiny brush holds enough for both lash lines.

It’s worth noting that you should only place the serum on your upper lash line. It’s not recommended to swipe it only your lower lash line. As for when to apply GrandeLash, there aren’t any specific guidelines. It’s important to find a time that you’ll stay consistent with for the best results. For me, that meant including it in my nighttime routine.

What are the side effects of using GrandeLash?

According to GrandeLash’s 90-day consumer perception study, none of the participants experienced any side effects. However, that doesn’t mean that there aren’t side effects. Remember the ingredient Isopropyl Cloprostenate I mentioned above? In rare cases, this can cause iris darkening and dark under-eye circles. The amount found in GrandeLash shouldn’t result in either of these adverse effects, but if you experience them, stop usage and consult with your doctor immediately.

The same goes for redness or irritation—there’s always a possibility of experiencing sensitivity when adding a new product to your routine. If this happens to you, quit using GrandeLash and chat with your doctor.

What happens when you stop using the GrandeLash Serum?

This is kind of a bummer—to maintain the long, luscious results you’ll need to continue using GrandeLash (womp). Once you stop regularly applying the serum, your lashes will eventually revert to their regular growth cycle and won’t appear as naturally long or voluminous.

My GrandeLash Serum review:

About my lashes:

I won’t lie—I am genetically blessed by the lash gods (thanks, Mom and Dad). My eyelashes are naturally very long and thick. But they’re also very blonde and their light color makes them look nearly invisible when I’m not wearing mascara. My excessive mascara usage over the years has definitely taken a toll on my lash health. Some areas along my lash line are even a bit sparse from me scrubbing my eye makeup off at the end of the night.

Every few months I like to give my lashes a little TLC with a lash serum to enhance their softness, restore thinning spots, and help them look more full.

My experience:

Like I said before, I’ve used GrandeLash in the past with stellar results, so it was a no-brainer to add it back into my routine for fluffier lashes. I began swiping a light layer of the serum onto my lash line every night in early October.

It does take a while to notice any sort of difference (consistency is key), so for the first two months, the process was slow and steady. I did experience some slight redness on my lids and lash line, which hadn’t occurred when I used GrandeLash in the past. Other than that my eyes weren’t itchy or irritated, so I continued use without any other side effects.

My results:

Fast-forward to January (almost four months of regular application) and it’s obvious that my lashes have grown like crazy. They now reach my eyebrows without mascara, and the sparseness I had been dealing with has pretty much disappeared. Plus, the bottle I’ve been using still has a ton of serum left in it, so I should be able to get a few more months out of it before needing a restock.

All that said, I really knew the serum was working after about two months when other people started commenting on how incredible my lashes looked—with and without mascara. It’s not abnormal for people to ask me what mascara I’m using, but I’ve never had people stop to tell me how long and full my bare lashes looked. The serum didn’t make my lashes darker either, which made this compliment even better. The compliments had me considering ditching mascara altogether for a moment. (Alas I am addicted to mascara, I love rich black fringe too much to ever stop using it.)

The final verdict:

Out of all the different lash-enhancing serums I’ve tried over the years, GrandeLash has repeatedly given me the best results. Without fail, I know that my lashes will look longer, become more dense, and feel softer after just a few months. My friends have also hopped on the GrandeLash train after seeing my results, and it works just as well for them. My best friend works in finance, and after using GrandeLash for a few months one of the bros on her floor asked her where she gets her lash extensions done. True story!

All of this to say if you’ve been searching for an effective way to lengthen and volumize your lashes, I 100 percent recommend trying out the GrandeLash-MD Lash Enhancing Serum.
