4 Essential Ingredients Every Eyelash Serum Needs

Eyelash serums have exploded in popularity over the last few years. With dozens of different brands all promising to give you longer fuller lashes, it can be hard to choose.

That’s why it helps to know a thing or two about what actually goes into eyelash serums, and how they work.

In this post you’ll learn about the four key ingredients that every safe and effective eyelash serum needs to help you grow longer fuller lashes.

Let’s dive in.

Eyelash growth serum - stimulate eyelash growth for longer thicker lashes

Essential Ingredient #1 Peptides

If you’ve ever looked into the ingredients behind popular anti-aging products, you may have seen the term “peptide” before. It's a useful ingredient often used in skin care products. It can stimulate collagen production, and help get rid of wrinkles.

But it can do wonders for your lashes too.

According to Connecticut based dermatologist Rhonda Klein “Peptides are chains of amino acids that are the building blocks of protein in the skin."

It turns out your eyelashes are made of proteins too. These proteins also benefit from being nourished with peptides. So it’s important that your lash serum has plenty of them.

How Do Peptides Help Your Lashes Grow?

Peptides are made of amino acids, which are the building blocks of proteins. Your eyelashes are also made of proteins composed of amino acids.

By supplying your eyelashes with the protein fragments in peptides, you supply your eyelashes with the raw material they need to grow. This promotes growth from within the hair follicle.

This is a much safer and healthier alternative to eyelash serums that use prostaglandins. Prostaglandins promote growth through a hormone like effect.

Prostaglandins are effective, but come with some nasty side effects like skin irritation, or permanent darkening of the skin around your eyes.

On the other hand, peptides generally don’t cause irritation, and don’t come with any harmful side effects.

Essential Ingredient #2 Biotin

The next ingredient every effective eyelash serum must have is biotin. Biotin is an essential vitamin that helps the growth of hair and nails.

Clinical studies have shown that biotin has a positive effect on hair growth. By providing your lashes with biotin you're supplying your hair with key nutrients it needs to grow.

How Biotin Gives You Fuller Lashes

This vitamin helps hair to grow through its effect on keratin. Keratin is a protein that makes up both hair and nails.

Biotin has been found to strengthen keratin. What this means for your lashes is that when you apply biotin, they’ll be stronger and less prone to breaking.

One of the main ways lashes look shorter is by breaking before they’re fully grown. If you want longer fuller lashes, it’s not enough just to grow more. You also have to make sure your lashes are strong, and won’t break easily.

Even a long eyelash will wind up looking short and thin if it’s brittle. Having biotin in your lash serum ensures your lashes will have everything they need to look long and full.

Essential Ingredient #3 Plant Stem Cells

What are stem cells and how do they help your eyelashes grow? This ingredient get’s pretty technical, but it’s an important part of any effective eyelash serum.

Research has shown that stem cells naturally reside at the base of hair follicles, and play a key role in hair growth.

Hair follicles grow in three phases. These three phases also apply to your eyelashes. The first is the anagen phase. This is where your natural stem cells play the most active role.

Stem cells are special because they have the ability to develop into different kinds of cells. In the anagen phase of hair growth your natural stem cells develop into cells called keratinocytes.

These specialized keratinocytes produce the part of your hair that becomes visible. They also process keratin, which keeps your hair looking full and healthy.

As we age, exposure to UV radiation reduces the regenerative capacity of the natural stem cells responsible for hair growth. This leads to hair that looks thinner and is more prone to breaking.

That's where plant stem cells come in.

How Plant Stem Cells Help Your Eyelashes Grow

Plant stem cells work by reducing the harm caused by UV radiation. The ingredients in plant stem cells such as anthocyanin, found in grape stem cells, help restore the regenerative ability of your natural stem cells.

By safeguarding your natural stem cells against the harmful effects of UV radiation, plant stem cells allow your eyelashes to grow and regenerate at a healthy youthful rate.

Essential Ingredient #4 Hyaluronic Acid

Acid may sound a little scary, but don’t worry. Hyaluronic acid is great for you, and it’s completely natural. Your body actually produces hyaluronic acid on its own. It’s found in your skin and even your eyes.

A lot of people take hyaluronic acid as a supplement for its many benefits. It’s main function is to keep your body moist and hydrated.

How Hyaluronic Acid Encourages Eyelash Growth

Hyaluronic acid should be present in your serum to keep your eyelashes hydrated. It acts like a conditioner for your hair helping your eyelashes look shiny and lush.

Hyaluronic acid excels at retaining moisture so you won’t have to worry about your lashes getting dry and more brittle over time. This protects them from breaking, which also helps growth.
