So let's start with the basics: 

What is GrandeLASH-MD Lash Enhancing Serum? 

GrandeLASH-MD is an iconic beauty breakthrough that is proven to promote the appearance of longer, thicker, healthier looking lashes in as little as 4-6 weeks. That’s because of its amazing ingredient complex including Isopropyl Cloprostenate - a prostaglandin analogue and hair conditioning cosmetic ingredient - plus other synergistic ingredients, such as Radish Root Ferment, Grape Seed Extract, Amino Acids, Honey & Aloe Vera. Our ophthalmologist-tested serum helps provide next-level lashes that are all your own, no falsies or lash extensions necessary!



  • GrandeLASH-MD Lash Enhancing Serum has been extensively tested by world-class, third-party research facilities
  • There have been 10 million tubes of GrandeLASH-MD sold & over 35,000 5-star reviews 
  • 97% saw more visible lashes* after using GrandeLASH-MD 

Now that we covered what GrandeLASH-MD is and what it does, let’s clear the air on the proper way to apply it! 

Wondering how to pick the best lash serum with so many out there to choose from?! We’re here to fill you in. 


Fact: GrandeLASH-MD is brought to you by the #1 Lash & Brow Serum Brand in the U.S.**

And that’s not by accident. Alicia Grande founded Grande Cosmetics over fifteen years ago, starting with superstar GrandeLASH-MD.  Since then, we’ve been moving & shaking with cosmetic beauty solutions that break the mold with instant & long-term benefits, really work & are tested by independent, third-party laboratories. We don’t just talk the talk, we back it up. 


Fact: Proper application is SO important when it comes to using GrandeLASH-MD. Using more than directed, incorrectly, or applying it more frequently will not yield quicker or better results. 

Some rumors suggest that if you apply GrandeLASH-MD more than once per day, you will see  faster results, but this is not the case!  

Proper application is very important and you only need to apply GrandeLASH-MD once per day. Rest assured, as long as you are applying the serum once per day for the first 3-months, you’ll see the appearance of longer, thicker looking lashes.

GrandeLASH-MD should also be applied to your eyelid sparingly, following your upper lash line (and the upper lash line only), just like a liquid liner! To clarify, not on the lashes themselves, in the eye, on the lower lash line or water line. 


Fact: GrandeLASH-MD is proven to be safe, with rigorous safety & performance studies under our belt. 

If you’re wondering if GrandeLASH-MD is safe to use, the answer is YES! And we can prove it. 

We prioritize safety, quality, and performance in all of our products. Besides industry-standard quality testing, GrandeLASH-MD has undergone numerous safety studies since it launched 15 years ago, including clinical studies, safety studies and even a toxicological review.


Fact: Sensitivities can happen when introducing any new skincare product, but there are things you can do to decrease the chances of them!

We realize everyone’s skin is unique and there is always a possibility of sensitivity when introducing a new skincare product like GrandeLASH-MD into your beauty routine. Just like Vitamin C, there may be an acclimation period as your skin gets used as a new product. 

Often, for users with sensitive skin, it is suggested that new skincare products be introduced at a slower pace. You can use the serum every other night for the first two weeks as you adjust to using a new product

Always listen to your skin! If sensitivity continues, a product may not be right for your skin.


Fact: GrandeLASH-MD contains cosmetic ingredients that do not cause eye color change or orbital fat loss. 

GrandeLASH-MD is a cosmetic product and does NOT cause periorbital fat loss or iris color change. Be aware…Anything that states differently is not supported by sound, clinical evidence and is misinformation!

In fact, as part of our commitment to ensuring safety, GrandeLASH-MD has completed an 8-month clinical review to track the experience of over 115 users on this subject, as well as a  toxicological risk assessment of GrandeLASH-MD's formula & individual ingredients.

Both of these concluded that GrandeLASH-MD is safe & does not present a risk for iris color change or periorbital fat loss. 

We weren’t kidding - we are serious about safety!


Fact: We hope you love GrandeLASH-MD as much as we do! 

If you’re thinking of using a lash serum, remember that not all lash enhancing serums are created equally, so you may not get your GRANDE results if you use another lash serum! We’ve been helping people achieve the lashes of their dreams for over 15 years and are proud to have a library of incredible before & after images from our real users.
