If you’ve used eyelash serums to boost the health and appearance of your lashes but are now switching your focus to your thin, unimpressive eyebrows, you may wonder if you can use the same products on both. After all, it’s all just hair, right? Wrong. Lash and eyebrow hairs are actually quite different from each other, from texture to appearance to growth cycles.

Let’s find out why eyelash growth serums work in the first place and discover if they’ll work on your eyebrows as well.

How Does Eyelash Growth Serum Work?

Lash growth enhancers got their start from Bimatoprost, a treatment for Glaucoma that helps with lash appearance as well. Growth serum for lashes works by keeping your eyelashes in the growth phase, or anagen phase, so that the lash line becomes thicker and fuller than before. Most serums are full of multi-vitamins and anti-oxidants that also improve the strength, length, and overall health of the eyelash follicle. Lash serums contain peptides that make for a healthy foundation for better volume. Growth serums are either prostaglandin-based, peptide-based, or vitamin-based.

These serums should be a regular part of your daily skincare routine if you are to see effective improvements.

What is in Eyelash Growth Serum?

There are a few different types of lash serums, and ingredients will vary slightly depending on the brand you’re using. The most common ingredients used in lash growth serum include keratin, biotin, sodium hyaluronate, panthenol (vitamin B5), peptides, botanical extracts, prostaglandin-derived ingredients, and a variety of vitamins. These natural ingredients condition, strengthen, hydrate, and lengthen your lashes.

Are Eyelash Growth Serums Safe?

When using eyelash growth serum, you must understand that safety is directed related to proper use. However, since the eye is an incredibly sensitive part of your body, and eyelid skin is some of the thinnest on the body, there are always risks to using products in this area.

When used properly, lash growth serum is perfectly safe long term. Of course, there are a number of potential side effects, and each person will react differently to the ingredients of the serum. Those that contain parabens are best avoided as well. An ophthalmologist can guide you toward making the best decision for your eye health when using a lash enhancer.

What Are the Common Side Effects of Eyelash Growth Serum?

When using a lash growth serum, there are a few things to watch out for. If you have sensitive skin, you may be more likely to react to the serum the first few times it is applied. If you continue to have a bad reaction, you could be allergic to one or more of the ingredients used. Other possible side effects include swelling and eye irritation, dry eyes, darkening of the skin at the application area, and possibly even brown pigment in the iris.

Even though lash serums are targeted at eyelashes, many can also be used on the brows. They contain very similar ingredients to eyebrow growth serums that help your eyebrow hair grow fuller, just as they help you obtain fuller lashes. Some serums are marketed as both lash & brow serum, but others marketed at just one may not work the same on both.

How to Grow Your Eyebrows

If your eyebrows are not the envy of anyone, you’re not alone. While there are many options for covering up a short natural lash, such as mascara, eyelash extensions, and more, there are aren’t as many choices for the brows. An eyebrow growth serum will help you maintain healthy hair follicles to prevent breakage and thinning of your eyebrows.

Why You Might Need Brow Enhancing Serum

Though thin brows used to be trendy, thick, full, shapely eyebrows are the standard in beauty these days. If you’re embarrassed by thin or patchy eyebrows due to hair loss or over-plucking, brow growth serums are the answer.

Stress and anxiety can actually have an impact on hair growth, and this can cause patchy or thin eyebrows. overuse of makeup products is another reason that someone may need some outside help growing thicker, healthier brows since harsh makeup can damage the hair follicles. User error when plucking can damage follicles over time since plucking is a traumatic event, and when plucked consistently over time, the hair follicle may be permanently damaged.

Genetics may also play a role, though, as some people naturally have very thin eyebrows. Older people may also notice a slow thinning of their once thick eyebrows as age reduces the number of hairs as well as the thickness of the eyebrow hair. A few other conditions that can affect the fullness of your brows include diet deficiencies, skin conditions like eczema, autoimmune disorders, or hormonal changes.

How Does Eyebrow Growth Serum Work?

Eyebrow growth serums contain peptides, essential oils, vitamins, and biotin that work together to strengthen the hair you already have, boost the production of new hair follicles, and condition and thicken the hair for a better appearance.

Growth serums need to be applied every day for an extended period of time for you to see results. If you stop using the serum, your eyebrows will revert back to their old appearance since they aren’t being boosted by vitamins, keratin, biotin, and fatty or amino acids.

Many eyebrow growth serums don’t add length to your brows but only condition and strengthen the hairs you already have. That’s why some people choose to use eyelash growth serums on eyebrows as well since they are usually more targeted for growth and length. The proteins in these serums work wonders on eyebrow hair as well.

Is Eyebrow Growth Serum Safe?

Though eyebrow growth serums are safe, those that contain peptides can cause some problems for those with sensitive skin. You may also have an allergic reaction to certain ingredients in these serums if you have a sensitivity to something found in the serum. All product types, including eyelash growth serums, are approved by dermatologists to be safe on the skin and around the eyes. However, if you have any concerns about using an eyebrow growth serum, you should speak with a dermatologist first, especially if you have any pre-existing skin conditions or have had a bad reaction to other products in the past.

What Are the Side Effects of Eyebrow Growth Serum?

Brow enhancer serum can cause similar side effects as eyebrow enhancing serums, including eye issues and skin irritation. Since you’re using it further away from the eyes, the chances of experiencing more severe side effects to the eye such as eyelid drooping are greatly reduced. The most common side effect experienced by those using brow enhancers is irritated skin due to an allergic reaction. Be sure to check the ingredients in the specific serum you’re using and test a small part of your skin first to check for a negative reaction.
