False strip lashes were once the only option to get luscious. Undoubtedly, the last decade was ruled by lash extensions. Lash extension before and after permanency and quality entirely depends on lash adhesive used for gluing on artificial lashes. Like other advancements in the false lash industry, the lash adhesive has evolved a lot.  Different types of lash glues have been introduced to simplify the process and increase the retention period without any harm to the skin or eyes.

Lash adhesives are of different types, they vary in formulas, drying time, retention level, staying power, and ease of removal. Using the wrong solution can lead to lash loss, eye damage, or serious allergies. Even the right formula demands lash extension aftercare.

Some classifications of lash adhesives are explained below that will surely help you know them well.

Different formulas

The basic formula of every lash adhesive remains the same, a bonding agent, stabilizer, colorant, and some other components for flexibility.

Cyanoacrylate (Cyan) is the foundation of lash adhesive, all lash glues consist of 80 to 95% cyan. 10 percent are other complex compounds such as carbon black, anthraquinone color, for color, hydroxyanisole or Hydroquinone as a stabilizing agent, acrylic resin as thickening agents.

The quality and type of lash adhesive depend on the type of Cyanoacrylate used in the formula. It’s the main bonding compound. The adhesion strength, drying capacity, fume level, and sensitivity all are due to Cyanoacrylate. It has the unique ability to bind quickly to human lashes, skin, and artificial fibers at the same time.

What is Formaldehyde?

You might have heard Formaldehyde, a controversial word in lash extension treatment. It’s not an ingredient; it’s a gas or fumes emitted during the curing of Cyanoacrylate. Some types of Cyanoacrylate emit more fumes than the others. You can’t avoid formaldehyde but choose an adhesive that emits fewer fumes.

Different colors of lash adhesives

Lash glues are available in two different types in terms of color, clear or transparent glue and black glue.

• Black lash adhesive

The black color is generally due to the colorant carbon black. Black glue is mostly applied to the clients because it helps to add definition and outline lashes just like bold eyeliner. The lash line becomes too prominent that you can skip the eyeliner. Moreover, it allows better blending and creates natural looks. The black adhesive is harmless but some may experience irritation from carbon, for them the other option is clear glue.

• Clear or transparent glue

When it comes out of the jar its white, after drying it becomes transparent. This type of glue provides a clean look rather than a darker effect. Colorful lash extensions are very popular nowaday. For better projection of every hue, clear glues are the right choice. Besides that clear glue works well for sensitive skins

Adhesion strength

Lash extensions are designed to last for anywhere around three to eight weeks. You can find different types of lash glues based on adhesion strength. The strength of glue highly depends on the kind of Cyanoacrylate used in particular formula. All cyanoacrylate variations are  combine with PMMA, another ingredient to increase the strength of the glue. Cyanoacrylate helps in curing while PMMA strengthens the bond.

Cyanoacrylate variants decide the type of strength you are going to have. For lash extensions choose sensibly what ingredients are most suitable for you?

• Methyl-Cyan: is the strongest industrial grade bonding agent. Lash glue containing it should never be chosen to apply lashes for its toxic properties. for safe results avoid a type of glue having Methyl
• Ethyl-Cyan: is mostly a part of the strongest lash adhesive. it’s safe to use on skin.
• Butyl-Cyan: glues containing Butyl-Cyanoacrylate are used for sensitive skins as they are hypoallergenic with low odor. Its adhesive strength is weaker.
• Alkoxy-Cyan: is the most expensive type of Cyan.  It has low adhesive strength but it is recommended for sensitive skins.

Although adhesion strength relies on the formula of the glue. Some other factors heavily affect their efficiency such as;

• Lash artist’s inexperience; incorrect attachment. Incorrect amount of glue
• The inappropriate environment of lash extension area.
• Not following lash extension aftercare directions.

Drying Time

There are two different types of glues when considering the drying time. Each type comes with its pros and cons. generally lash technician’s expertise matters when it comes to deciding which type is better.

A lashing style may also require a specific variation of dry timing. For example, pre-made volume lashes are applied well using fast-drying glues with a thicker consistency.

• Fast Drying glues

Fast-drying glue dries in approximately 1- 2 seconds. They have a stronger formula of Cyan. The strong fume and odor may cause irritation and inconvenience to sensitive skins.

• Slow drying glues

It takes 5-6 seconds to set dry these glues. The formula is lighter and less irritant so they are lighter and good for sensitive skin clients and beginner lash artists.

Fume level

Lash glue fumes are responsible for watery, irritant eyes. In many cases, they may cause allergic reactions too.  When you decide to take lash extensions you have the liberty to select a glue type that emits lesser fumes. Here again Cyan plays a crucial role.

• The stronest Cyan variation methyl has the strongest fume level they, therefore, are never recommended to apply near eyes.
• Ethyl-Cyan fume emission is on an average scale. Most lash extension clients can bear it without any harm to the eyes.
• Butyl and Alkoxy-Cyan have the lowest fume omission level and are safe for sensitive skins. although they have the lowest adhesion strength.

Take Away

Lash adhesives have different varieties nowadays. It is difficult to say which type of lash glue is best to use. It’s because lash glue performance highly depends upon, environment, proficiency of the lash artist, and individual preferences. One type may suit a person but not another. Only a professional and licensed lash technician can select one for you after the glue test. What is due on you is lash extension aftercare for longer, safer results.
