"Top 5" Eyebrow Growth Serums On The Market


We found 2022’s best eyebrow enhancer products to give you thick, full brows, fast.

Gone are the days of skinny brows being in—we all want thick, full brows that stand out. But with hundreds of eyebrow serum products available (along with confusing brow serum reviews), it can be hard to find an eyebrow enhancer that really works to grow brows, let alone one that is made without harmful chemicals.

Many eyebrow booster products contain unnecessary chemicals. Not only do these chemicals not work, but they can also cause sensitivity and irritation. Prostaglandin is one such chemical found in some eyebrow serums that is known to cause potentially harmful side effects. Therefore, we prefer an eyebrow serum without this controversial ingredient.

Our team of beauty experts tested hundreds of the top eyebrow serums, looking to factors like ingredients, speed of results, effectiveness, manufacturer ethics and value to select the top seven eyebrow enhancer products on the market. We also considered factors such as a money-back guarantee, which allows customers to send the product back if they aren’t satisfied. These are “Top 5” eyebrow serum products that caught our attention and delivered results for our testers.

For this review, I and my professional team have had extensive researches in eyelash serum enhancers industry. We read myraid of beauty blogs, and also tried many lash serum products to provide you useful information to help you choose the best eyelash enhancers on the market. At the end of the day, it doesn’t matter how expensive the product is or how big the brand name is, the most important thing is if it provides results and offers the best value for money. Of course, we cannot guarantee that these products will work for you as each person has varying growth length and skin type. But based on our researches, those eyelash serums that we studied have amazing results.

NourishBrow Eyebrow Growth Serum was the best eyebrow serum selected by our testers, who praised its effective, natural formula and fast results. Testers were thrilled to see that their brows looked thicker and fuller after using NourishBrow for just two weeks. They could see more definition, and sparse areas that usually needed brow pencil starting to fill in.

NourishBrow does not contain prostaglandin, a potentially harmful ingredient found in many eyebrow serums. Instead, it features a unique complex of potent peptides, biotin and natural ingredients found in luxury skincare products.

This top eyebrow serum contains myristoyl pentapeptide-17 and myristoyl hexapeptide-16, known as “Growth Peptides.” This powerful peptide pair fortifies brow hairs to support a thicker appearance. Red grape stem cells help to protect against the effects of DHT, a hormone that interferes with hair growth and longevity. Plus, botanical extracts, amino acids and proteins help brows to appear thick, full and shiny.

NourishBrow eyebrow serum is a safe, natural and effective option that is also dermatologist and ophthalmologist tested. It is vegan and does not contain hormones or parabens.

With this potent brow serum, we were pleased to see a combination of real results with the benefits of a natural, prostaglandin-free formula.

GrandeBrow Brow Enhancing Serum is a top-rated eyebrow serum available at major retailers like Sephora. It encourages the appearance of thick, bold brows in four to six weeks, according to the company.

We liked that the makers of GrandeBrow eyebrow enhancer stand behind their product by offering a 90-day money back guarantee. The company is also up-front with its ingredients, making them easily accessible on their website. This eyebrow booster contains natural ingredients like ginseng, chamomile and bearberry extracts.

However, GrandeBrow contains an ingredient that alarmed us: cloprostenol isopropyl ester, which is a form of prostaglandin. Our favorite brow serums don’t contain this harmful ingredient, which is known to cause skin discoloration. The bottom line: We are more likely to recommend a product that is prostaglandin free.

GrandeBrow is also sold at Walmart, which raised concerns with our testers that it could be diverted or unsafe product.

GrandeBrow Pros

Contains botanical extracts, antioxidants and hyaluronic acid to nourish and condition brows
The company reports positive results from a consumer perception study
Does not require a significant amount of product with each use
No animal testing
Easy to purchase online, including at major retailers like Sephora and Amazon
Offers a money-back guarantee

GrandeBrow Cons

Does not contain peptides

Contains a form of prostaglandin

The company reports that some users can experience mild irritation

This German-made product is one of the higher-end—and most expensive—brow enhancer options our experts tried. The company advertises improvement in eyebrow thickness and shape in six to eight weeks. Furthermore, Eyebrow Renewing Serum has been given an excellent rating and is certified as dermatologist tested by Dermatest.

M2 Beauté’s brow growth serum contains a unique ingredient, black sea rod oil, which was initially derived from living coral. The company claims that this ingredient is now obtained ethically and that it supports brow hairs during their growth phase.

However, we quickly learned that a high price tag isn’t always met with high-quality ingredients. This eyebrow enhancer contains methylamido dihydro noralfaprostal, known as MDN, and norbimatoprost, a form of prostaglandin. This is a major red flag and would make us reluctant to use this eyebrow serum on a regular basis.


M2 Beauté Pros

Certified by Dermatest
Contains botanical ingredients, hyaluronic acid and provitamin B5 to condition brows
Formulated without parabens
The company claims it can improve eyebrow thickness in six to eight weeks
Easy to purchase on Amazon, with a 60-day money-back guarantee

M2 Beauté Cons

Very expensive (over $107 for 5 milliliters of product)

Contains MDN and norbimatoprost, a potentially harmful prostaglandin ingredient

Company website is difficult to navigate, and the company is not transparent with its full ingredient listing or testing practices

The international company makes it difficult to purchase directly from their website in the US

LiBrow Purified Eyebrow Serum features an interesting ingredient list, including walnut shell extract, copper ferment and krameria traindra root extract. It also contains common eyebrow-boosting ingredients like peptides and panthenol. This eyebrow enhancer claims to nourish hair follicles so that brows appear full, thick and healthy.

Unfortunately, some users did not see significant results when using this product. We also weren’t able to find vital product information, including clinical studies or before and after images, on the company website. Though the company does offer a 90-day money-back guarantee, we’d still like to know more information about a product before we buy it.

LiBrow Pros

The company includes a comprehensive ingredient list on its website
The formula features unique natural ingredients, including walnut shell extract and krameria traindra root extract
Contains conditioning glycerin and panthenol
Not tested on animals
90-day money back guarantee

LiBrow Cons

It’s expensive, at about $30 per mL of product

The company does not provide clinical testing results or data

It was a challenge to find vital product information about how the product works and the company’s manufacturing practices

Testers did not see a significant improvement in eyebrow shape and thickness after use

We were impressed to see that BrowFood’s eyebrow serum is made with Ecocert-compliant materials. Its ingredients have also been evaluated for biodegradability and eco-toxicity. In fact, over 99% of the total ingredients are derived from natural origin. Consumers like us who prefer a natural product will love that this eyebrow serum does not contain parabens, prostaglandins, petrochemicals, silicones, synthetic dyes or mineral oils.

Results do take some time to appear. In testing results published by the company, 100% of women noticed an improvement in overall brow appearance in 16 weeks. While some users appreciated the host of natural and hydrating ingredients to condition brows (including coconut fruit water, orange fruit water and lavender flower water), they did not see dramatic results when using this product. It may work better as a basic brow conditioner, but not as an eyebrow growth product.

BrowFood Pros

Certified organic and made with natural fruit and herbal extracts and conditioning ingredients
Free of ingredients considered to be harmful, including prostaglandin, parabens, phthalates, sulfates, synthetic fragrances and silicone
Vegan and the company does not conduct animal testing
Gluten free and a smart choice for users with sensitivities

BrowFood Cons

Some users didn’t see dramatic results

It can take up to 16 weeks to see results

The company does not appear to offer a money-back guarantee

Expensive, at $90 for under 3 mL of product
