Remember that all adhesives need moisture to cure. If you live in a low humidity climate, you can expect your adhesive to be thinner and dry more slowly than normal. Try using a humidifier with the door closed. The stiffness that occasionally occurs in the adhesive is simply due to the adhesive being too cold or too hot.
When the adhesive drops below 18 °C, the viscosity (thickness) changes. This gives the adhesive a fibrous texture. In most cases, cyanoacrylate (the main component of eyelash glue) is known to be the substance that causes glue allergy. Bolkin believes that storing one type of glue is sufficient, as long as the work environment is heated.
Remember to use a new drop of glue as soon as it starts to get tangled or sticky, otherwise it will be less effective. Lash Professional eyelash extension glue will last up to 6 weeks after opening if properly stored. You've probably learned that glue for eyelash extensions heals by its reaction to moisture (specifically, cyanoacrylate does). Keep in mind that this is not only limited to customers, but it can also happen to eyelash artists, who are constantly exposed to the smoke of extension glue.
DO NOT use cotton products to clean the mouthpiece, as this may clog the eyelash adhesive or cause the cap to stick to the mouthpiece, making it difficult or even impossible to use. One of the main causes of glue allergy that many technicians overlook is the health status of the eyelash customer. Too much or too little moisture in the eyelash room can cause sticky situations for cyanoacrylate (CA) adhesives used for eyelash extensions. While a small percentage of customers develop an allergic reaction to glue for eyelash extensions, this allergy in and of itself is not particularly dangerous.
When eyelash glue (specifically the ingredient, cyanoacrylate) is exposed to too much water before it dries, it can heal quickly, become white, hard and brittle. Eyelash artists can develop a glue allergy by inhaling a strong smoke of eyelash glue for an extended period of time. Cyanoacrylate, the main active ingredient in the adhesive for eyelash extensions, must be polymerized for the eyelash glue to cure.
