What to Look For in a Lash or Brow Serum

These days, it feels like there are lash and brow serums everywhere you look. From mass retailers to prestige department stores, Instagram to TikTok, lash and brow serums are some of the hottest products on the market—and many of them boast some pretty impressive claims.

But the fact of the matter is, not all brow and lash serums are created equal. If you want to see results, you don’t want just any lash or brow serum; you want the best lash serum and the best brow serum.

So the question is: how, exactly, do you find the high-quality lash and brow serums that are going to make a real difference in your lashes and brows? Let’s take a look at everything you need to know about how to choose a lash serum and how to choose a brow serum that will give you the results you crave.

What are lash and brow serums—and what are the benefits?

First things first. Before we jump into how to choose the best lash and brow serums, let’s quickly touch on what lash and brow serums are—and what kind of benefits they can deliver to your natural lashes and brows.

A lash serum is a cosmetic product that’s applied to the lashes to strengthen, protect, and hydrate lashes and improve flexibility and shine—which can make lashes lusher and healthier. And a brow serum works similarly, just for the brows; it’s applied on the eyebrows to hydrate, protect against breakage, and improve shine and flexibility—which, similar to lashes, can transform brows to look bolder and healthier.

Lash serum benefits may include:

Stronger lashes. Again, lash serums are all about strengthening the lashes.
More dramatic looking lashes. Because lash serums strengthen and protect the lashes, they can help minimize breakage—which, in turn, can make lashes appear lusher.
Easy to use. If you’re not a person that likes complicated beauty products, you’ll love a good lash serum! These products are easy to apply and don’t require you to devote much extra time to your beauty routine. Simply apply RevitaLash® Advanced daily for best results.

Brow serum benefits may include:

Increased shine. No one wants a dull brow! Brow serums can boost shine in the brows, which can give them a healthier, more lustrous appearance.
Less breakage. Brow serums can help prevent breakage—which can make brows look bolder and more beautiful.
Works well with other products. You can use brow serum in conjunction with other brow products—like a brow pencil or brow pomade that can help brows look fuller.

Choosing the best lash and brow serum for you

You know what lash and brow serums are. You know some of the potential benefits. Now, let’s jump into how to choose the right products for your lashes and brows.

In order to choose a top lash serum and top brow serum, you need to know what you’re looking for. Some factors to consider when evaluating lash and brow serums include:

Ingredients
Like any other beauty products, lash and brow serums are only as good as their ingredients.

Some lash serum ingredients you’ll want to look out for include:

Antioxidants. Antioxidants will help protect and revitalize the lashes, which can make lashes appear healthier—so look for serums with antioxidant-rich plant extracts (like ginseng and Swertia japonica).
Amino acids and B vitamins. Amino acids and B vitamins help to fortify, smooth, and condition the lashes.
Peptides. Peptides can help strengthen and hydrate the lashes.

When you’re shopping for brow serum, some brow serum ingredients you’ll want to be on the lookout for include:

Peptides. Just like peptides can help strengthen and hydrate the lashes, they can also strengthen and condition the brows.
Humectants. Humectants—like calendula—help brows retain moisture.
Amino acids and B vitamins. Similar to what they do for lashes, amino acids and B vitamins help to fortify, smooth, and condition the brows.

You also want to look for lash and brow serums that are formulated without parabens, phthalates, or ingredients that can irritate the eyes or skin.

STEP 01 | RevitaLash® Advanced

Remove makeup and residue. Keep in mind, oil-based makeup removers and cleansers can leave behind a film which may create a barrier between your lashes and the lash conditioner. It’s important to wash off any residue.

STEP 02 | RevitaLash® Advanced

Once a day, apply one thin line of RevitaLash® Advanced directly to clean, dry upper eyelashes only, above the lash line. Dip applicator brush into the bottle one time for both eyes. Use sparingly, as dripping into the eye may cause irritation or other unwanted effects. Let dry completely (2-3 minutes) before applying additional beauty products or going to sleep.

Use this lash and brow serum guide to find the right products for your beauty routine

If you’re not familiar with the products, finding the right brow or lash serum can feel overwhelming. But now that you know what to look for in a top lash serum and top brow serum, you’re armed with the information you need to find the best products for your beauty routine. So what are you waiting for? Get out there and find the perfect brow and lash serum for you!

Physician-formulated and dermatologist-reviewed

Lash and brow serums (particularly lash serums) are applied close to the eyes. You want to make sure that you’re using products created with safety top of mind—and the best way to ensure you can trust your serums? Go for products that are both physician-formulated and dermatologist-reviewed.

Choosing products formulated by physicians and reviewed by a dermatologist can ensure you’re not buying any products that contain ingredients known to be irritating to the eye area.

Formula
Every person has different wants and needs in their beauty products—so, when shopping for lash and brow serums you'll also want to look for a formula that matches your specific preferences.

For example, if your eye area is sensitive, you’ll want to look for a lash serum for sensitive eyes. If you’re an animal lover, you’ll want to look for a cruelty-free lash serum, cruelty-free brow serum, vegan-friendly lash serum, and/or vegan-friendly brow serum.

Industry accolades
Industry accolades—like beauty awards or praise from celebrities, influencers, and beauty experts—don’t always guarantee that a product is high quality. Some awards or endorsements can give a product more credibility. Before you pick a brow or lash serum, do a quick search. Look for any reviews or mentions of the product to find out if it’s trustworthy.

Reviews/Customer experience
One of the best ways to predict your experience with a product is by looking at other people’s experience with that product. Or, in other words, when you’re choosing a lash and/or brow serum, make sure to read the reviews.

If the products have overwhelmingly positive reviews, the likelihood that you’ll also have a positive experience increases—while if the products have overwhelmingly negative reviews, chances are you won’t have a great experience either.

You should also look for consumer studies. These studies help identify what kind of product experience you can expect as they reflect real, unbiased feedback from people who are unaffiliated with the brand.

Bottom line? Social proof is incredibly important when it comes to finding a lash or brow conditioner that actually delivers—so before you commit to a product, see what other people are saying about it.
