Lash Boost: Pros and Cons

Many women use lash boost as an alternative to enhance the appearance of their eyelashes. While mascaras and a good set of false eyelashes are other options that can work wonders if you want to enhance the appearance of your eyelashes, it is not a permanent solution.

Lash Boost is known to be effective as it can condition and moisturize the lashes and give the appearance of fuller, longer, darker-looking lashes. This article will review Lash Boost, the pros and cons, and how to use the product.

What is Lash Boost?

Lash Boost is a nightly eyelash serum that conditions and moisturizes the lashes to promote the appearance of fuller, longer, darker-looking lashes. It uses a blend of keratin, biotin, and peptides to boost eyelash growth. Keratin is formed by the combination of 18 amino acids and is the key structural material making up hair, nails, and the outer layer of the skin.

Biotin is a water-soluble vitamin that assists with healthy cell formation and growth, leading to healthy hair, skin, and nails. While it is known to be effective, it also contains a questionable ingredient Isopropyl Cloprostenate. However, Isopropyl Cloprostenate is now used in the cosmetic industry to grow eyelashes and eyebrows.

Therefore, it is essential to note that this ingredient has the potential to cause many side effects, such as eye irritation, dryness, redness, itchy eyes, flaky skin, burning, and pain. Unlike Latisse, which the FDA considers safe and effective for lash growth, Lash Boost isn’t. Rather it is sold as a serum and not a medication.

Pros And Cons of Lash Boost


1. It Is Easy To Use

Apply the product to your lash line each night before you go to sleep with the provided applicator. Improper use can lead to eye irritation and other side effects.

However, the application should only be made on your top lashes; if used overnight, it will be absorbed by your bottom lashes while you sleep. You may see results in as little as 4-8 weeks.

2. It Nourishes The Follicles

The Lash Boost promotes new growth and makes your eyelashes look fuller and longer.

3. It Contains Proprietary Technology And Key Ingredients

Ingredients in Lash Boost are formulated to improve sparse lashes and promote better retention. The critical ingredient is the Lash Boost Technology, a complex of several ingredients that will not harm the sensitive eye area and help prevent breakage overnight. The ingredients also help to rejuvenate the lashes by keeping them conditioned and moisturized.

3. It Can Be Used As A 2-in-1 Product.

Apart from using the Lash Boost on your eyelashes, you can also apply it on your brows to make them look fuller.


  1. It is expensive
  2. The instructions are pretty unclear as it is unknown what will happen if the product does not apply or rest on the lashes evenly.
  3. The ingredients may produce unwanted side effects such as ocular irritation, hyperemia, iris color change, macular edema, etc.

What Are The Side Effects Of Lash Boost?

Over the years, regular use of Lash Boost has caused the eyes to appear sunken because the fat around the eye socket starts to shrink. Many customers have experienced different results, so studying the product carefully before using it is essential. Some of the side effects include;

1. Irritation

Because the Lash Boost is applied close to your eyes, irritation may occur. However, rinsing your eye with water will be enough to reduce the irritation.

2. Tingling/Redness

Another side effect of Lash Boost is the tingling or redness of the eye. If these symptoms persist, it’s advisable to see a doctor and stop using the product.

3. Darkening Of The Eyelid

The product contains ingredients that may cause darkening of the eyelid.

To avoid any of these side effects, carry out these two procedures;

Perform A Patch Test

Before you begin, please remove any makeup on your face and ensure it is clean and dry. Apply a small amount of the Lash Boost serum to a small area of the lash line and allow it to dry before applying any other cosmetics. Wait for at least 24 hours and check for reactions.

Reduce The Frequency Of Your Application

Although, It may take a few applications for your skin to get used to the product. If you experience any side effects for the first few days after application, you should stop applying them daily until they disappear. When it disappears completely, gradually increase your usage.

How To Apply Lash Boost

Lash Boost can be very intimidating, but it is a quick and easy process; here is how you can apply a lash boost.

Step One

Wash and dry your eye area before applying. Wipe out all your makeup and wash your face with your regular facial cleanser. Once you’re done, use a soft towel to gently clean your lashes and eyelids until they are completely dry. Note that any water left in your eye might cause the product to be less effective.

Step Two

Wipe any excess product off the wand to ensure only a little lash boost liquid on the brush. Ensure you don’t apply too much of the product at once, as it could cause eye irritation.

Step Three

Now it’s time to apply. Make sure your eyes are closed, hold the wand parallel to your lash line, and slowly swipe along your upper eyelid to the outer corner of your eye.

Step Four

Repeat the same product on the other eye. Dip the wand into the Lash Boost, swipe along your upper eyelid to the outer corner of your eye, and wipe away the excess.

Step Five

Finally, wait for the product to sit for at least 90 seconds to get dry. Make sure you wait this long before you go to bed or apply any product to your face.

Note: If you forget and skip applying Lash Boost for a day, apply as usual the following day, and do not apply more frequently, as overuse can lead to irritation or itchiness. The product will make your lashes appear fuller and thicker by applying it once a day.

How Often Should You Use Lash Boost?

Lash boost requires a consistent application to achieve results. Be sure to apply once daily at night to enhance lash durability and protect against breakage. In about four weeks, you will see a difference and the best results in eight weeks. Women using Lash Boost reported seeing the following results after about eight weeks.

  • 90% of them noticed the appearance of fuller-looking lashes
  • 85% of them noticed the appearance of longer-looking lashes.
  • 63% noticed the appearance of darker-looking lashes.

What Happens If I Stop Using Lash Boost?

Just like every other lash enhancement product, if you stop using Lash Boost, your eyelashes will return to normal, and you will stop seeing results. In other words, your lashes will shed and grow back to their regular length.

If your lashes were thin and brittle, and the Lash Boost made them fuller and thicker, then they’d go back to normal. Dermatologists recommend that once you have achieved the desired appearance of lashes, continue to use the Lash Boost as directed to maintain the appearance.
