Urban Decay Cosmetics Lush Lash System Review

Thick, dark and long eyelashes are a sign of beauty, health and youth for some women. To help women achieve this look, Urban Decay created the Lush Lash System, a combination of serum and mask designed to create 25% longer and thicker lashes in just 2 weeks.

What Does It Claim To Do?

The Lush Lash System is supposed to create longer, thicker lashes that resist loss and breakage. In addition, a description of the product says the “clear gel-like serum accelerates the growth of your lashes with peptides.” [1]

Does It Work?

There are many products on the market which manufacturers claim give women thicker and more beautiful lashes after just weeks or even days of use.

To find out if Urban Decay’s Lush Lash System lives up to the promises in the product description, I scoured the web to research its ingredients and find out what users have said about its effectiveness.

Is It Safe?

There are no listed safety warnings for this product, although people with sensitivities or allergies to any of the listed ingredients should avoid using it.

In addition, people with sensitive eyes or who develop frequent eye infections should avoid applying the lash system, as it may introduce bacteria into the eye area.

How Is It Applied?

Urban Decay recommends people who want to thicken their lashes use the applicator brush to spread the mask and serum evenly at the lash line and allow it to penetrate the root of the hair. Inside the root, the manufacturer claims the products will stimulate keratin to thicken, lengthen and fortify lashes.



The primary ingredients in the serum are water, glycerin, boric acid and sodium chloride.


Glycerin, or glycerol, is a sugar alcohol compound commonly found in cosmetic products throughout the world. It has moisturizing, smoothing and humectant properties, making it ideal for products which must be applied while wet, such as lotions, creams and certain types of makeup. [2]

Boric Acid

Boric acid is a weak acid with a large number of consumer and industrial uses. In cosmetic products such as the Lush Lash System, it is often used as an antiseptic, as it is effective at killing bacteria. It is also used as a preservative and as a lubricant. [3]

Sodium Chloride

Sodium chloride is another name for salt. In cosmetics, it’s often used to thicken liquids or prevent them from running. However, it is also known for its tendency to dry out skin and hair. [4]


The primary ingredients in the mask component of the Lush Lash System are water, copernicia cerfera, and stearic acid.


Water is the largest ingredient in many liquid-based cosmetic products and is used simply as a vehicle for the other chemicals and compounds in the solution. [5]

Copernicia Cerfera

Also known as carnauba wax, copernicia cerfera is a type of wax derived from the leaves of a palm tree native to Brazil. It is often used in cosmetics due to its hypoallergenic properties, as well as its tendency to add shine to any surfaces it comes into contact with.

This can have the effect of making hair and lashes appear darker and longer. [6]

Stearic Acid

Stearic acid is a saturated fatty acid used in everything from soaps, detergents and household cleaners to cosmetic products. It is used to create a thickening effect in products, including shaving cream and body lotions.

It also has cleansing properties and is effective at mixing with oils and dirt on the skin, allowing them to be washed away. [7]

Is It Worth Trying?

The main ingredients in the Urban Decay Cosmetics Lush Lash System appear to be fairly standard for similar lash-boosting products.

The majority of the primary ingredients in both the serum and mask are common in most cosmetic products, and other types of eyeliner and lash systems contain similar ingredient profiles.

However, it’s important to note the sheer number of positive reviews found on the web, as the majority of people who tried the product found it was effective at increasing the size, length and fullness of their eyelashes.

Urban Decay claims people who use the product see 25% longer lashes in 2 weeks, 40% longer lashes in 4 weeks and 63% longer lashes in 6 weeks.

While it’s difficult to verify those claims, it appears most people who used the product were satisfied with the results they achieve in short periods of time.

My research into the ingredients shows there’s nothing exceptional about what’s actually inside the mask and serum of the Lush Lash System.

However, people who are determined to get thicker and longer lashes may want to give it a try despite its less than impressive or groundbreaking ingredients, as it comes highly recommended by almost everyone who uses it.
