How to grow long lashes with Grandelash Serum

Lashes are having more than a moment, but an entire movement. Even the most minimalist makeup wearer seems to still want long lashes, whether via lash extensions, false lashes or mascara cocktailing.

What if your natural lashes could grow longer?

I have an option for you that is cheaper than lash extensions by a lot, better for your lashes, can be easily integrated into your existing routine and isn’t sold via MLM and doesn’t require a prescription.

I’ll be telling you all about GrandeLash-MD Lash Enhancing Serum and why it’s the way to go.

GrandeLash Formula

GrandeLash-MD Lash Enhancing Serum is a serum that encourages lash growth. They can’t say it grows them, but I’ll just say it for them: it makes your lashes grow longer.

GrandeLash serum contains various humectants, vitamins and amino acids, but most importantly, the star of the show, the active ingredient, prostaglandin I.C. While the other ingredients definitely promote healthier, stronger lashes by hydrating, conditioning and strengthening, the Prostaglandin I.C. is what actually makes them grow. And grow they do.

GrandeLash-MD is

  • Cruelty free
  • PETA certified
  • Paraben free
  • Safe for contact wearers
  • Safe for use with lash extensions
  • Ophthalmologist tested

To preface, I’ve always had decent lashes, not amazing, but good. I also get lash lift and tints semi-regularly. The last lash lift I had was October 17, 2019, so 4 months ago, therefore it’s likely 100% worn off by now.

I’m mostly going to focus on the Lash Serum today because my lashes have had the most dramatic transformation.

I have been using GrandeLash-MD Lash Enhancing Serum and GrandeBrow just shy of the 3 month full result mark.

How to use it

The GrandeLash-MD Lash Enhancing Serum has a thin brush, very similar to a liquid eyeliner. You will apply it the same way, close to the lash line. I apply both the Lash Serum and GrandeBrow after doing my night time skincare routine before bed. It’s easy and quick to do.

You will want to apply it every night for the first 3 months. After that, you can just apply a few nights a week to maintain.

The Results

The before photo shows my natural lashes, without a lash lift, not wearing any eye makeup, brows filled in.

The after shows my natural lashes, without any eye makeup, naked brows too, after almost 3 months of faithful GrandeLash and GrandeBrow use.

Now, here are my natural lashes with and in Tornado.

False lashes who?! I am shocked every time I put mascara on lately.

I can confidently say that my lashes are longer, thicker, fuller and more curled, all on their own. They say to expect full results at 3 months but I saw amazing lashes at 2 months.

I’ve also had good luck with GrandeBrow. I’ve been able to grow new hairs on the inside and outside edges of my brow where hair wasn’t before.

Before: September of 2019. I started using GrandeLash and GrandeBrow December 1st, 2019.

I love the way my natural lashes look so so much. I have no desire to wear false lashes and will continue to use GrandeLash for the rest of my life pretty much.


  • No irritation
  • No change in eye color that I have noticed (it is a risk with light eyes)
  • Ophthalmologist tested
  • Safe for contact wearers
  • Easy to incorporate into routine
  • Easy to apply, not sticky or gooey
  • Cruelty free, PETA certified


  • Cannot use while pregnant
  • You can’t completely stop once your lashes reach desired length
  • You need to be consistent. I don’t think I skipped more than 4 nights in the last 3 months. I’ve heard from others who weren’t consistent, that their results weren’t like mine.

How does GrandeLash compare to other lash serums?

The only other lash growth serum I have personally tried is Revitalash, which caused me to have itchy eyes so I stopped using it.

I’ve seen many clients in my makeup chair that have used Rodan + Fields Lash Boost and no doubt, their lashes are lovely. However, a handful of clients have told me that they experienced irritation with it and had to discontinue use. That being said, at a price point of $155, that is just under 2.5x more than GrandeLash. Oh, and Rodan + Fields is MLM, as I’m sure you know, so there’s that added pressure.

Do I recommend GrandeLash?

Yes, yes, yes! This lash serum completely surpassed my expectations, works beautifully and has given me lashes and brows I wasn’t even sure were possible.

If you have eyelashes, even the tiniest ones, you need to try this. It absolutely works and I’m so happy with the results.

    I have been using it faithfully for 16 days and do not see a bit of difference. How long before I see some type of growth. I’ve used Rapid Lash in the past, and I saw some results by now.

      Le Grande Lash, just like Latisse, usually takes up to 4 months for the full results, because that is about how long it takes for your lashes to completely grow out from your lash line. Claims that it can happen in a few weeks are just not reality! Le Grande Lash works with consistent use.
