Grandelash Vs. Latisse Vs. Rapidlash
In recent years, lash serums have become some of the most popular cosmetic products for enhancing the appearance of your eyes.

An eyelash growth serum contains a growth-enhancing formula that extends the lash growth cycle, resulting in thicker and longer eyelashes. It also offers other benefits, such as preventing breakage and premature fallout, and is the best sustainable beauty option you can get.
However, selecting the right brand is crucial for getting the best results when buying products like eyelash serums. And, that is where things get a little tricky, as there are countless brands on the market to select from.
Fortunately, we’ve decided to put together a detailed guide that compares the three most popular brands available on the market. This will make it easy for you to select the most suitable option without wasting time or effort.
So, without further ado, let’s dive in!
GrandeLash MD vs. Latisse vs. RapidLash – A Comparison
1. GrandeLash MD
GrandeLash MD is one of the most popular eyelash growth serums and has become a household name in recent years. It is manufactured by Grande Cosmetics LLC, an American company owned by Alicia Grande. Grande first formulated this serum for her own use, and when she realized that it could deliver desired results, it was launched on the market in 2008.
Active Ingredients
GrandeLash MD eyelash growth serum contains a prostaglandin [1] analog known as isopropyl cloprostenate [2]. It helps lengthen the natural growth cycle of eyelashes while also increasing their number. Other ingredients in GrandeLash MD include hyaluronic acid [3], L-Proline [4], an amino acid essential for healthier lashes, and a botanical extract blend that reduces hair loss.
Another key ingredient is glycosaminoglycans [5], which help lock in the moisture, and boost luster and lash resilience. Apart from this, this eyelash serum contains several vitamins, botanical extracts, and amino acids that nourish and condition your lashes.
Cost
The GrandeLash MD lash serum is available in two sizes – 2 and 4 ml. A 2 ml bottle should ideally last for about three months and costs $65, while a 4 ml bottle will cost $120. And, the best part is that you do not require a prescription to purchase it and can order it online directly from the website.
Ease of Use
The GrandeLash serum is fairly easy to use and requires only a single stroke on the eyelid above the upper lash line. It is applied like a liquid eyeliner and does not require more than a single dip. Due to this reason, it also tends to last for a long time.
2. Latisse
Most people looking for an eyelash serum have heard of the Latisse brand, as it is the only FDA-approved prescription lash serum. Latisse is manufactured by the global pharmaceutical company Allergan Inc, best known for its Botox beauty products. It has been clinically proven to make your eyelashes longer, fuller, and darker.
Active Ingredients
Latisse contains bimatoprost [6] as its active ingredient, another prostaglandin analog that can enhance eyelash growth dramatically. It works by extending the hair growth cycle of your lashes, helping them grow longer and thicker past their natural growth cycle.
This eye serum also includes sodium chloride, citric acid, sodium phosphate, dibasic, and purified water. Sodium hydroxide or hydrochloric acid may also be added to adjust the pH.
Cost
While the cost of Latisse varies depending upon the location, its average price for a 3 ml bottle ranges from $90 to $120. This should last for about 30 days, and if you want a longer-lasting option, there is the 5 ml bottle, which costs from $140 to $160.
Not only is Latisse one of the costlier options, but also requires a doctor’s prescription, which you should consider in the total cost.
Ease Of Use
Each bottle of Latisse comes with a pack of sterile applicators that make it easy to apply the serum. Place one drop of the serum on the disposable applicator, and apply the applicator to the upper eyelid at the base of the eyelashes. Use a different applicator for the other eye and remove excess serum using a tissue.
3. RapidLash
You may have come across the RapidLash brand in popular magazines like Marie Claire and Elle. Manufactured by International Research Laboratories, this eyelash serum was launched in 2008 in the UK, quickly becoming a favorite of many women.
Active Ingredients
When it was originally launched, RapidLash contained isopropyl cloprostenol as its active ingredient. However, this was later replaced by more natural hair-strengthening ingredients such as panthenol [7], various peptides like myristoyl pentapeptide-17 [8], and biotin [9]. However, the current product does contain prostaglandin, though in a lesser quantity.
Apart from that, RapidLash includes hexatein 1 complex for conditioning, moisturizing, and fortifying the eyelashes. Also, some polypeptides comprise various amino acids, panthenol, soybean oil, pumpkin seed extract, and other vitamins and minerals.
Cost
RapidLash is among the most affordable hair growth serums you can get, with a 3 ml bottle costing less than $50 on the official website. However, it is available for almost half the price on online shopping platforms like Amazon.
Ease Of Use
RapidLash also comes with an easy-to-use applicator that you can use to apply the serum to the base of the eyelashes. It can easily be applied using a single dip in the serum.
Detailed Comparison Of Various Factors
Now that you know about the three brands and their offerings, it’s time to take a more detailed look at the various factors to be compared.
Ingredients
GrandeLash MD comes out on top as far as the ingredients are concerned, since it contains a prostaglandin analog, which results in thicker and longer lashes. While proven results also back Latisse, GrandeLash MD includes other complementary lash-boosting ingredients that help nourish the lash line. Also, these ingredients can counter the irritating effects of the prostaglandin.
In this case, RapidLash contains various botanical extracts and peptides that work to nourish and strengthen the hair follicles. The prostaglandin ingredient is also present in a very little amount, compared to that in GrandeLash MD and Latisse.
Overall Cost
The first thing to remember when you decide to use eyelash serums is that they are an ongoing expense. If you stop using the serum, your eyelashes will return to their original length and thickness. That is why it is important to consider the long-term cost of the product you’re looking to buy.
And, when it comes to the pricing of these three products, RapidLash seems to be the most sensible choice since it delivers impressive results while remaining an affordable option. RapidLash does not require a doctor’s prescription, thereby resulting in greater savings.
When comparing the prices, Latisse turns out to be the costliest option since its regular price is higher than the other options and requires a doctor’s prescription. GrandeLash MD is the most feasible option that is neither as expensive as Latisse, nor as budget-friendly as RapidLash.
Ease Of Use
All three recommended products are fairly easy to use, making it difficult to select the best one. However, in this case, Latisse is an outstanding choice because it comes with a complete pack of applicators that can last for many days. Also, the serum itself dries pretty quickly, which is an added advantage.
Which Is The Best Option?
The final verdict may appear to be surprising to many. While Latisse is the only FDA-approved option and has built up a remarkable reputation for itself, it is not the perfect choice for the majority of users. This is because it has an extremely high price compared to the other options and requires a prescription from a doctor, which is an additional hassle.
That is why the overall winner would be GrandeLash, which is considered to be the best eyelash growth serum by many. It offers exceptional results, thanks to the effective ingredients, and is also priced reasonably, making it accessible to the majority.
A Few Noteworthy Mentions
Besides the top three options, here are a few other brands that can be considered.
LashLuxury
The first brand that we would like to mention here is LashLuxury, which is a relatively new entrant in the industry. Despite that, it has gained a large following since it contains several useful ingredients that boost hair follicle growth.
LashLuxury is a Canadian brand and a part of the Clean Beauty Movement. That is why the company only uses completely safe yet effective ingredients for the skin and body.
What’s more, LashLuxury offers a 100% satisfaction guarantee, which enables you to get a complete refund if you are not satisfied with the lash serum.
Active Ingredients
LashLuxury daily eye serum contains three main ingredients – B vitamins, plant extracts, and peptides. The peptides in the serum include myristoyl pentapeptide-17 and acetyl tetrapeptide-3 [10], which help stimulate keratin and collagen production.
Similarly, the B vitamins include Panthenol (B5) and Biotin (B7), which have a moisturizing effect that strengthens weak eyelashes and helps repair them. Finally, the plant extracts include red clover flower extract [11], cucumber fruit extract [12], aloe leaf juice [13], and Camellia Sinensis leaf extract [14]. These contain antioxidants, anti-inflammatories, and other soothing plant ingredients.
LashLuxury is hormone-free, fragrance-free, cruelty-free, paraben-free, phthalate-free, and hypoallergenic. This makes it one of the few options in the segment which meets such requirements.
Cost
LashLuxury eyelash serum is available in three different sizes. The smallest 2 ml bottle costs only $75 and lasts for about three months. The next option is a 3.5 ml bottle, which is available for $120 and can last for five to six months.
Finally, there is the Lash Pro, the largest size bottle that contains 6 ml of the serum, costs $180, and can easily last for 10 to 12 months. LashLuxury does not require a prescription and offers free shipping on all orders.
Ease Of Use
Like the top three brands, LashLuxury comes with an applicator for applying the serum to the lashes. Just dip the applicator into the serum, and run it along the base of the lashes. However, avoid using it with contact lenses as they can absorb the serum easily.
Lash Boost
Lash Boost is another excellent option among eyelash serums that provide effective results. It is manufactured by Rodan + Fields, which is a marketing company. The product was launched in 2007 and contains several beneficial ingredients.
Active Ingredients
The key ingredients in the serum include keratin, biotin, sodium hyaluronate, and isopropyl cloprostenol. One of the most important ingredients, isopropyl cloprostenate, is also present in the best-performing GrandeLash.
Biotin is associated with hair growth, keratin is an important protein required for nourishment, and sodium hyaluronate can help relieve eye dryness and soreness.
Cost
Lash Boost is not a medication and does not require a medical prescription for purchase. The 5 ml bottle costs $155 and will last for around two months.
Ease Of Use
Unlike other brands, Lash Boost does not come with sterile applicators, but comes with an applicator brush. Applying the serum using the brush may be more complicated than using conventional applicators.
Final Thoughts
Eye serums can be highly beneficial for women who want longer, thicker lashes with minimum effort. While there are lots of options to select from, it is important to consider certain factors before making a choice. This is especially true since a serum that might work for one person may not work for another.
Some products may contain some ingredients that may not suit everyone, while others may not be that simple to use. So, you need to consider certain factors like the ingredients, ease of use, and budget when selecting an option.
That said, it is time for us to conclude this informative guide. Until next time!
