How to find a high quality, effective, and safe eyebrow serum!

Film star, celebrity or supermodel? In the world of the rich and beautiful, long and voluminous eyelashes are a must together with distinctive, full, and well-groomed eyebrows to round off a perfect appearance.

But which secret is responsible for such expressive and eye-catching brows? In very few cases, good genes are the reason. However, an effective brow serum will do the trick in most cases.


As with almost every beauty innovation, eventually, numerous manufacturers on the market will label their product as the best or the most effective. It’s the same spiel for eyebrow growth serums.

Facts are even manipulated in some instances, along with false claims, touting the product as the go-to serum for bushy and bold brows.

Many of these claims cannot be substantiated or verified by studies. The ingredients and additives that more thorough studies and tests often unearth stand in no relation to proper brow care, let alone promote the growth of the eyebrows. Even worse, they can trigger adverse reactions.

How does a good eyebrow growth serum work?

Usually, the brow hairs grow out for about 4-6 weeks and then fall off naturally after the resting phase is over within a matter of months.

At this point, the eyebrow serum comes into play: it ensures that the growth phase of the brow hairs is significantly prolonged while simultaneously activating the growth of new hairs.

As a result, the number of brow hairs can multiply quickly, and the length of the hairs can increase thanks to the extended growth phase.

Not just some far-fetched advertising claim by the cosmetics industry: International and reputable studies from the US, Japan, and the UK also confirm the amazing effects of the key ingredient. It’s the first active substance proven to activate eyebrow growth and sprout new brow hairs.

With this in mind, we took a closer look at the eyebrow serum market and examined some of the top brow boosters. Our rating system of the 5 best eyebrow growth serums, took such factors as effectiveness, ingredients, speed of results, safety, price/performance, and the trustworthiness of the manufacturer into consideration.

The results of our eyebrow growth serum check-up

Eine Anmerkung vorab

“We highly recommend using one of the five eyebrow serums from this ranking list. We believe these are the best in their class, plus you'll avoid a bad buy as many brow serums contain questionable ingredients and a dubious formula.”

Overall rating

Pros: Orphica Brow

  • innovative formula of active ingredients based on proven findings
  • contains many natural and nourishing substances, cruelty-free!
  • award-winning eyebrow growth serum with hundreds of positive online testimonials
  • the majority of users report speedy results within 14 days
  • consistently achieves top results in the trade press and tests
  • also suitable for over-plucked eyebrows
  • clinically tested
  • reputable performance of the internationally known brand ORPHICA from France
  • reasonable price & free delivery with a 90-day money-back guarantee

Cons: Orphica Brow

The eyebrow growth serum overall winner does everything right, thus occupying the more than deserved first place. This brow serum works with a prostaglandin derivative, achieving an unparalleled level of effectiveness with a quick onset of results.

In our test, both the length and thickness of the eyebrows improved considerably. Despite its high quality, the ORPHICA BROW Brow Conditioner remains affordable. Of particular note are the series of synergy effects created through the complex formula of active ingredients.

Also, the main active ingredient ensures that initial visible results often occur after about 14 days, always depending on your age and genetic makeup. However, you should be able to see the first real signs of increased growth within 30 days by the latest.

ORPHICA BROW Practical Test

Nothing can provide better proof than the following before-after picture: ORPHICA BROW has achieved flawless results. The rather inconspicuous and sparse eyebrows have been transformed into spectacular eyecatchers, nigh impossible to beat in terms of ampleness and expressiveness.

Before Image After Image

In addition to the eyebrow growth serum “BROW”, the eyelash growth serum “REALASH” by ORPHICA was also used. It utilizes the same miracle ingredient and lets the lashes sprout (easy to recognize on the before and after picture).

A grand total of 28 days has passed between the two photos. Our tester is au naturel in both images.

Our conclusion

ORPHICA’s top serum BROW is a great choice for anyone who wants thicker, healthier, and more distinctive eyebrows.

ORPHICA products tend to occupy the pole position in tests.

The trade press and responsible parties at beauty magazines absolutely love the eyebrow growth serum BROW as well as its kissing cousin REALASH, the eyelash growth serum. BROW also repeatedly gets rave reviews from customers, who are particularly impressed by the prompt initial results.

With the distinct honor of doubling as the best eyebrow serum, the overall winner of our test ORPHICA BROW convinces us across the board. Not only are the results excellent after the application phase, but they also kick in right away. The eyebrows are visibly thicker, more intense in color, healthier plus malleable at will (more hairs equal more room for creative brow styling!).

Based in France, the ORPHICA brand enjoys a stellar reputation and is considered the leading expert in its field.

2M2 BEAUTÉ Eyebrow Renewing Serum

Overall rating

Pros: M2 Beauté

  • scientifically proven ingredients
  • combines MDN and black sea rod oil for maximum effectiveness
  • from a well-known German company
  • practical applicator brush
  • toxin-free
  • fast visible results
  • provides optimal hydration in several ways
  • particularly convenient applicator for easy handling

Cons: M2 Beauté

  • not vegan
  • contains a questionable ingredient according to the European Commission, Cosmetic Ingredients & Substances

No cutting corners with M2 BEAUTÉ: The serum combines MDN with black sea rod oil as a hormone-like substance from nature (but produced synthetically) to deliver the first-class efficiency while a variety of scientifically proven ingredients round off the picture. The unique applicator brush could also inspire enthusiasm.

The growth serum comes from a cosmetics industry giant: M2 BEAUTÉ distributes its products in more than 40 countries worldwide. The manufacturer maintains a diverse product portfolio, consisting of different skincare products for eyelashes, eyebrows, and the face. All of these products are designed and produced according to strict quality guidelines by this German company.

Parabens, sulfates, and other potential toxins are banished from the premises. Peptides aren’t included either as black sea rod oil, together with biotin, takes over that role. Deductions are made due to the use of triethanolamine, said to favor the formation of nitrosamines and suspected of being carcinogenic. However, it’s worth remembering that only tiny amounts of it ever come in contact with the skin, since serums are never used as generously as creams.

Our conclusion

Our worthy second place costs a bit more than the overall winner, another reason for this seeding instead of the pole position. Otherwise, the combination of MDN and synthetic black sea road oil is quite innovative and more than compelling. In our test, the special brush allowed for a precise, optimally dosed application. The packaging of the serum oozes understated elegance and high quality.

A questionable ingredient has to be counted negatively. On the other hand, there are many active, scientifically proven ingredients in the serum. By no means the most expensive serum on the market, it also isn’t made for a shoestring budget. A small surcharge for the more than well-known brand name of a reputable company is to be expected.

3RevitaBrow® Advanced Eyebrow Conditioner

RevitaLash® RevitaBrow® Advanced Eyebrow Conditioner

Customer feedback (1351 Reviews)
Expert evaluation
Overall rating

Pros: Revitabrow®

  • from the trailblazing eyelash growth serum brand RevitaLash®
  • high-quality applicator and bottle
  • scientifically proven growth through a prostaglandin derivative
  • with peptides
  • rapid onset of action
  • honored with an Allure Award
  • matching eyelash growth serum, also available from RevitaLash®
  • excellent results observed after three months

Cons: Revitabrow®

  • steep price
  • use of a known allergen (chlorphenesin)

RevitaBrow® from RevitaLash® Cosmetics is an absolute classic from the USA. Unfortunately, this status adds to the purchase price. Still, the growth serum makes up for this through its combination of hormone-like, synthetic, and natural active ingredients. The serum even received the “Allure Award – Best in Beauty” in 2014.

RevitaLash® and RevitaBrow® are trademarks (and products by the same name) of RevitaLash® Cosmetics, an American company that usually produces its serums in Vietnam. Considered the pioneer of the eyelash growth serum market, the manufacturer enjoys a very high profile. Therefore, RevitaLash® products can also be found in virtually every test and on every best-seller list. Americans particularly like to resort to this “home brand.”

RevitaLash® uses a patented formula that contains many natural and synthetic substances. Dechloro Dihydroxy Difluoro Ethylcloprostenolamide is the prostaglandin derivative responsible for hair growth. Extracts of ginseng and glycerin are added to the mix, both known for their nourishing and moisturizing effects. Biotinoyl Tripeptide-1 fortifies the fine hairs and helps create a natural, protective film around the follicles, which can extend the maximum life of individual hairs. On the other hand, chlorphenesin is a questionable ingredient that also occurs. This substance is a suspected allergen and can cause skin irritation.

Our conclusion

A great product, RevitaBrow®, serves as a testament to its craftsmanship. The only drawback is the use of a now known allergen, which could easily have been avoided. Apart from the fantastic results, the application is a breeze thanks to the easy handling of the high-quality applicator. This trailblazing brand, which brought eyelash growth serums to so many people back in the day, proves why its excellent reputation is still justified. Unfortunately, the steep price of RevitaBrow® will probably keep many potential customers at bay. Hence, it’s only an option for people with “deep pockets” that trust in the American beauty pioneer.

4RapidBrow® Eyebrow Enhancing Serum

RapidBrow Eyebrow Enhancing Serum
Effectiveness ingredients
Customer feedback (983 Reviews)
Expert evaluation
Overall rating

Pros: Rapidbrow®

  • first visible changes after just 4 weeks
  • intense nourishing effect
  • effective combination of active ingredients
  • relatively affordable price

Cons: Rapidbrow®

  • comparably little content
  • must be applied twice a day
  • the brush makes a localized application difficult

Over the course of our product testing, we also examined the RapidBrow® Eyebrow Enhancing Serum more closely. We concluded that this eyebrow growth serum ranks in the middle, thanks to its price. The test subjects were basically satisfied with the results but felt that the applicator was a bit awkward. However, those who got the hang of it were rewarded with eyebrows that increased in strength and grew with a precise application of the RapidBrow® Eyebrow Enhancing Serum. Overall, still a good value for money.

The manufacturer touts the product as a safe and gentle way to develop healthier, stronger and fuller eyebrows in just 60 days.

The eyebrow serum RapidBrow® Eyebrow Enhancing Serum contains an active ingredient complex called Hexatein®2 Complex. It’s an innovative formula that consists of six different substances. First of all, the growth serum serves up a cocktail of amino acids in the form of polypeptides that boost hair growth. Next up, this brow serum features vitamin B7, aka biotin, for maintaining healthier hair roots. Panthenol, aka vitamin B5, provides the fine brow hairs with some extra TLC.

To boot, the RapidBrow® Eyebrow Enhancing Serum contains keratin for strengthening the hairs from the inside as well as sweet almond extract and apple fruit cell extract. While the sweet almond extract ensures that the brows are supple, shiny, and soft, the revolutionary apple cell extract acts as a natural fountain of youth for the hairs and skin.

Our conclusion

The RapidBrow® Eyebrow Enhancing Serum is a compact and relatively effective brow serum, though our testers rated the applicator handling as cumbersome. This rang especially true for when only certain areas needed to be treated and not the entire eyebrow. The biggest shortcoming yet has proved to be the twice-a-day application of this growth serum. Of course, the resultant double consumption also translates into increased costs. Its intense conditioning effect is a particularly positive feature of the RapidBrow® Eyebrow Enhancing Serum.

5ForChics ForBrow Eyebrow Enhancing Serum

FORCHICS ForBrow Eyebrow Enhancing Serum

Customer feedback (516 Reviews)
Expert evaluation
Overall rating

Pros: Forbrow

  • affordable price
  • international prominence
  • natural ingredients

Cons: Forbrow

  • very long delivery time
  • many disgruntled customers
  • unclear whether growth can really be achieved

For quite a few months now, the manufacturer of ForBrow has been promoting its serum across the various social media channels worldwide. That’s why we’ve also included this eyebrow growth serum in our test.

Based in Los Angeles, the US manufacturer comes across as trustworthy, and the design of the brow serum looks promising.

According to the manufacturer, the ingredients of this eyebrow growth serum are all of natural origin: Purified water, sodium chloride, benzalkonium chloride, citric acid, disodium phosphates, cellulose gum, hyaluronic acid, active factor, and polypeptides.

Upon closer inspection, the experienced user of an eyelash or eyebrow serum will soon realize that none of the ingredients are proven to be responsible for hair growth. It’s fair to say that the active substances will nourish and pamper the fine hairs. However, growth is doubtful.

The relatively long shipping time, estimated to be anywhere from 2 to 6 weeks by the manufacturer, doesn’t exactly help matters either. Customers who clearly voice their dissatisfaction via the Trustpilot portal also confirm this issue.

Nonetheless, customers abound who describe the success of the serum. Due to its low price that factored into our ranking system, this serum got away with a “sufficient” rating. However, if you’re looking for a safe bet, then we recommend choosing an eyebrow growth serum that occupies one of the top four spots. For example: Our test winner ORPHICA BROW.
