RapidLash Review: My Secret Weapon for Fabulous Lashes

I’ve always had short and sparse eyelashes that scream … help me! But I’m not a fan of fake lashes, so when I heard about eyelash growth serums, I thought it was genius and decided to try one out.

I chose Rapidlash Eyelash Enhancing Serum for this experiment because a friend of mine recommended it to me and the company has a great reputation.

So, did it live up to the hype? Did it transform my lash game?

Let’s find out!

Why Try a Lash Serum

I am a beauty professional who is always looking for products to test for my clients. I have always had really light, short, and sparse lashes. They got even worse when I started wearing lash clusters daily for many years. Although I will still likely wear lashes because I like the dramatic look, I have always wanted to try a serum to see if I could even heal my natural lashes as much as possible.

So… this is what my lashes looked like before this 30-day challenge.

My hope is that the short stubby lashes fill in more and I regrow the ones that have fallen out quickly. This will also make it easier for me to apply lash extensions when I decide to do so. I would like to not have to always wear them and still have nice lashes that I can just throw some mascara on as well.

My 30-Day Experience With RapidLash Serum

Week 1: The Initial Encounter

The packaging is a little flimsy but the product itself is solid. The applicator is a thin paintbrush you just swipe right above the lash line once a day. It is easy to apply. The directions are clear and easy to follow.

Here’s a quick video I made showing how easy it is to apply!

The product does burn if you get it in your eyes. So far I haven’t noticed much of a difference in my lashes, but I did not expect a whole lot in the first week. Disclaimer, I have a faded permanent eyeliner tattoo.

Week 2: Halfway Hustle

I am starting to notice a little growth at the 2-week mark. So far everything is going well. I have very sensitive eyes and skin and haven’t had an issue unless it gets in my eyes when I rub them too soon after.

In the two-week photo, you can notice a little bit more thickness and the lashes starting to fill in. I am excited to see what the next two weeks show!

Week 3: The Plot Thickens

Moving into week 3 I am noticing a little more fullness. Also noticing mascara is going on and looking a little better than on the short stubby lashes. I still did not have any side effects. I am very sensitive to things, especially my eyes, and this didn’t bother them.

Week 4: The Grande Finale

In the last week, I noticed more fullness through most of the lashes, except those short, stubborn outer corners I have due to wearing false lashes for many years.

I was hoping those would fill in a little more, but they are much shorter than the rest so I didn’t expect too much. Overall, it was slower progress, but if you continue to use it, I think it would make a big difference!

When I compare my before & after images side-by-side I can notice the difference. Truth be told, it’s not crazy, but it’s there. And I only applied it for 1 month. Generally, the manufacturers recommend a longer period before assessing the results.

Ingredients

Water (Aqua), Butylene Glycol, Hydroxyethylcellulose, Sodium Hyaloronate, Octapeptide-2, Copper Tripeptide-1, sh-Polypeptide-1, Cucurbita Pepo (Pumpkin) Seed Extract, Glycine Soja (Soybean) Oil, Glycerin, Hydrogenated Lecithin, Rhizobian Gum, Biotin, Dicalcium Phosphate, Panthenol, Pantethine, Dipotassium Glycyrrhizate, Allantoin, Sea Water (Maris Aqua), Alcohol, Isopropyl Cloprostenate, Phenoxyethanol, Disodium EDTA, Citric Acid, Chlorphenesin, Sorbic Acid, Sodium Oleate, Potassium Sorbate, Sodium Hydroxide.

I know it’s a mouthful, but Isopropyl Cloprostenate is the ingredient you should pay the most attention to in this formulation.

This active ingredient is what’s known as a prostaglandin analog, which mimics the hormones that your own body produces to help promote lash growth. Having said that, it doesn’t come without some concerns.

Some other key ingredients:

• Biotin: Also known as Vitamin B7, Biotin improves eyelash health, strength and structure. It will help the hair become more resilient and less prone to falling out.
• Copper Tripeptide-1: This peptide helps increase the production of collagen and elastin. This can strengthen and volumize your eyelashes. It also has anti-inflammatory properties.
• Panthenol (Pro-Vitamin B5): This is a key ingredient in many product’s formulations. It is very well known for its ability to moisturize, soothe, heal, and regenerate the skin. For eyelashes, it conditions the hairs making them appear longer and more voluminous.
