There are many different aspects of beauty, whether it is skincare, haircare, makeup or any other beauty applications to achieve the kind of look you want. A lot of these routines are centered around our face; hence one must be careful not to hurt one's eyes, inhale some chemicals or even inject any product as they can cause harm to our health. For a few years now, many people have been opting for eyelash extensions or fake eyelashes to complete their beauty routine. These are done by professionals and while they do ensure safety, things can certainly go wrong, affecting your eyesight. Dr Saurabh Sethi, a US-based doctor trained at Harvard University had warned us about a common beauty product: eyelash glue. He explained that some brands of eyelash glue may release a dangerous chemical that could have serious health consequences, including, in rare cases, blindness. While many people may be focused on the tools used, and how it can hurt your eye with one wrong move, the glue used can also be a big reason for hurting your eye health. Chemical Culprit: Formaldehyde In an Instagram video, the doctor explained that certain eyelash glues can release formaldehyde, a chemical also used to preserve bodies. He cautioned that while fake eyelashes are increasingly popular, the adhesive often contains this chemical. Formaldehyde can lead to allergic reactions, thinning, and even permanent loss of natural eyelashes. The doctor further stated that in very rare instances, it could even result in blindness. To reduce this risk, he advises either avoiding fake eyelashes or opting for formaldehyde-free adhesives. Why is Formaldehyde in Eyelash Glue? Experts explain that formaldehyde helps make lash glue last longer and stick better. However, even in small amounts, this chemical can trigger problems like shortness of breath, headaches, and skin irritation. A 2022 study published by the American Contact Dermatitis Society found that a significant number of eyelash glues contained formaldehyde. Specifically, 75% of 20 professional products and four out of 17 consumer glues released the chemical. Surprisingly, only two of the consumer glues actually listed formaldehyde as an ingredient. Cyanoacrylate Connection According to a lash retailer, Lash Base, the main ingredient in all lash adhesives is cyanoacrylate, which is made from formaldehyde. They state that after cyanoacrylate is formed, the lash adhesive goes through a purification process to remove excess formaldehyde. This process purifies the glue, making it safe for use and leaving only trace amounts of the chemical behind. Given these warnings, it's always wise to be cautious and consider the ingredients in your beauty products. Fake Eyelash Safety Guidelines The American Academy of Ophthalmology explains different nuances that could entail how safely your eyelashes are being installed. Here are some points you must keep in mind when getting eyelash extensions. Why Infections Happen Infections can pop up if the salon isn't super clean. Also, imagine sharp tools near your eye – if something slips, it could hurt you. So, hygiene and careful application are super important for your eye's safety. Allergic Reactions to Glue Some lash glues have chemicals like formaldehyde, which can cause an allergic reaction. This might make your eyes hurt, itch, turn red, or swell up. It's a big deal, especially since these glues aren't checked by federal agencies. Other Potential Problems Pulling or rubbing your extensions can actually damage your own lashes, sometimes for good. And very rarely, tiny fibers from the extensions might get stuck under your eye, which could even need surgery to fix. How to Get Lash Extensions Safely Want extensions the right way? Always check out the salon and the person doing your lashes. Ask about their experience and the glue's ingredients. It's always best to be prepared and ask lots of questions.
