A Complete Guide to Eyelash Extension Adhesives: Which One is Best?

Jul. 19th,2023

Main Ingredients in Lash Extension Glue:

Cyanoacrylates: Cyanoacrylates are the primary active ingredients in most eyelash extension glues. These molecules form strong bonds with other materials, ensuring the secure attachment of lash extensions to natural lashes. Cyanoacrylates consist of two substances: ethyl cyanoacrylate and methyl cyanoacrylate. Ethyl cyanoacrylate is commonly used due to its longer bonding time, while methyl cyanoacrylate has a shorter bonding time and is less likely to cause irritation.

Methanol: Methanol, an alcohol, is often present in eyelash extension glue as a solvent for the cyanoacrylate molecules. It helps break down the particles, facilitating easier bonding with natural lashes and ensuring longer-lasting attachment. Methanol also acts as an adhesive activator, activating the adhesive properties of the glue upon contact with moisture from natural lashes, resulting in stronger bonds.

Polymers: Polymers are frequently used in eyelash extension glues to thicken the solution, providing a smoother consistency for easier application and better adhesion to natural lashes without causing irritation or discomfort. Polymer-based glues are typically more expensive but offer longer bonding times, making them worth the investment for extended lash retention. They also prevent clumping or flaking during application, which can lead to premature shedding or damage to natural lashes.

Black Glue:

Black glue is suitable for clients with naturally darker or thicker lashes. It offers enhanced definition and opacity compared to clear glue, making it ideal for those seeking a bolder lash look. Black glue sets faster than clear glue, allowing for efficient and quick work. However, it's generally not recommended for clients with lighter lashes, as the color of the adhesive may show through, resulting in a less natural appearance.

Carbon-Black Eyelash Extension Glue:

Carbon-black lash extension glues contain carbon and black pigments, making them perfect for darker lashes. These glues are typically thicker than clear glues, ensuring longer-lasting results and better retention of false eyelashes. They also have a faster drying time, enabling you to complete your work more efficiently.

Clear Glue:

Clear glue is ideal for clients with naturally lighter or finer lashes, as its color won't interfere with their natural look. Many clients prefer the subtle and natural effect provided by clear glues, as they enhance their beauty without appearing overly dramatic or noticeable. Although clear glues have a slower setting time, they offer a longer-lasting bond that can last up to 8 weeks when applied correctly.

As a lash artist, understanding the ingredients used in different types of eyelash extension glue is essential for ensuring the safety and effectiveness of the products used on your clients' lashes. Most eyelash glue products contain combinations of cyanoacrylates, methanol, and polymers as active ingredients. Each type has its unique properties that make them suitable for different applications, depending on the desired look. By considering these factors, you can select the appropriate glue to achieve the desired lash style for your clients.
