5 Lash Serums That Work: The Most Effective Lash Serums 2023

Lash extensions, fancy mascaras, and false eyelashes are great options for people who want to enhance their eyelashes, but this treatment can’t last for as long as you want them to. Lash extensions can last up to six weeks, but keeping up with refill appointments every two weeks takes up all your time and money plus, there is also a risk of an allergic reaction to the lash glue for those with sensitive skin.

While lash growth serum might be one of the solutions to getting fuller and healthy lashes, they only help the lashes grow longer by preventing breakage, but they do not contain active ingredients to enhance lash growth. Despite this, let’s look at the five best lash growth serums.

Most lash serums work by conditioning the lashes by allowing them to appear more volumized and hydrated but may not contribute to the actual growth. The serums are a must-have because they ensure you get desired results that don’t disappear when it’s time to take your makeup off at the night’s end. However, some common ingredients active in lash serums are peptides, prostaglandin, and hair conditioning, which all work to support healthy lash growth though the formulas vary from brand to brand.

Ultimately, lash growth serums are entirely safe if properly used, but just like any skincare product, they could provoke an allergic reaction in some people. Although it depends on the person whether a lash serum is safe or not, some people can react to the specific peptides, oils, or vitamins, and symptoms can include redness around the eye area, itchiness, irritation, and inflammation. Always check in with a physician before trying a lash serum, especially if you have sensitive skin.

Also, you can do a patch test before using a serum; dab a small amount of the serum on a test spot away from the eyes to see if you have an allergic reaction. If you have an allergic reaction, stop using the product and consult an ophthalmologist.

What To Look Out For In A Lash Serum

Various lash serum brands are available in many stores today, and they all claim to give longer, fuller, and thicker lashes within a few weeks or months. However, we all purchase these serums without knowing if the product will work and help us achieve longer and thicker eyelashes, and the only way to find out is by checking the product’s ingredients.

1. Peptides

Peptides in lash serums are a good indication that they can boost the appearance of your lashes and fortify lash hairs because they are believed to promote hair growth from within the follicle and lengthen the growth cycle. To enhance your lashes, you must catch each follicle as it prepares to grow or when it is already growing. This means that you must use it consistently and use it for at least three months or more for visible results.

2. Biotin

Biotin is a water-soluble B vitamin often used to promote hair growth, and it also improves the foundation of Keratin to stop and even reverse hair loss. Lash serums containing this ingredient are recommended to help your lashes grow long and strong.

3. Conditioning Formulas

To get long and healthy lashes, you will want to look for a formula containing conditioning ingredients to keep them from breaking out.

Frequently Asked Questions

1. What Happens When You Stop Using Lash Serum?

The most common benefit of lash serum is that it makes eyelashes grow in length and not in thickness. So if you stop using the serum, your lashes will revert to their original length and thickness.

2. How Long Should You Use Lash Serum?

To achieve desirable results, apply the serum daily for at least 2-3 months. Use at night after cleansing, and avoid touching your eyes or rubbing them for at least an hour so that it can take time to absorb. Approximately one lash serum should last for three months, and when you’ve finally achieved your desired length, you can proceed to apply the serum 2-4 times a day to maintain your lashes.

3. Does Lash Serum Give You Dark Circles?

The most common side effect of lash serums is the stimulation of pigment, and it can lead to dark circles and possibly a darker eye color if the serum gets into the eye by accident. This is because prostaglandin can also dilate blood vessels and cause redness and enlarged vessels on the eyelids and chronic eye redness. Therefore, paying attention to your skin when using a lash serum for the first time is advisable.

4. Does Lash Serum Age Your Eyes?

The lesser-known side effect of lash serum is that it causes loss of fat around the eyes, which gives the appearance of sunken eyes.
