Ingredients to Avoid in Lash Extensions

Lash Serum

While we all love the glam of lash extensions, safety's gotta come first. Professional lash products are the key to captivating look, but poor compound can result in irritation, allergies and complaints among lash clients. So, it's crucial for both lash techs and clients to know what's in those lash products, especially which ingredients they should avoid at all costs. Knowing the ingredients inside and out is the key to keeping things safe and sound. This article is here to shine a light on the harmful ingredients often found in lash extension products.


Eyelash Adhesives

Commonly Used Harmful Ingredients


Formaldehyde is often lurking in lash adhesives as a preservative, but it's bad news for health. Exposure to formaldehyde can trigger allergic reactions, cause breathing problems, and irritate your client’s eyes. Prolonged exposure can lead to even more serious health issues. So steer clear of eyelash glues that have formaldehyde!


Lash artists should avoid latex in lash adhesives to keep things safe and comfy for their clients. Latex is a common allergen and can cause such reactions like itching and redness. Even if someone isn't allergic, latex can still irritate the sensitive eyes. Thankfully, there are plenty of great latex-free adhesives out there that work like a charm without the risks. By choosing these, you show you're serious about client safety and top-notch service. In a nutshell, ditching latex means happier, healthier clients and a stronger reputation for you!

The future is now, which means that even if someone is prone to allergies, it shouldn’t stop them from getting those adorable extensions, if their tech is properly equipped, ofc!


Lash Shampoo

Commonly Used Harmful Ingredients

Parabens & Sulfates

Parabens are often used as preservatives in cosmetic products, including lash shampoos, but they're not the best company. They've been linked to hormone disruption and skin irritation, and prolonged exposure can lead to even more serious health issues. Then there are sulfates—cleansing agents that can strip the skin and hair of natural oils. In lash shampoos, sulfates can cause dryness and irritation, which isn't great for the health of natural lashes or extensions. So, it's best to avoid these ingredients to keep lashes fabulous and healthy!


Oil is the worst enemy of the eyelash extensions and your lash glue. It’s like a Kryptonite to the Cyanoacrylate, as it breaks and dissolves it, resulting to grand retention fiasco. So any type of oil is something you should forget like a worst nightmare. So, even the beauty routine is something everyone should take seriously, and don’t let oils close to their eyes.


We can think of better use for alcohol then adding it to the lash shampoo. Otherwise, it can overdry the lashes, leading to an extremely unpleasant result. So, it’s better to safe the alcohol for special occasions and keep eyes and skin unharmed.


Lash Serum

Commonly Used Harmful Ingredients

Prostaglandin & Analogs

Prostaglandin analogs are often used in lash serums to give lashes that extra growth boost. But watch out—they can bring some pretty bad side effects along for the ride. We're talking changes in eye color, darkening of the eyelids, and irritation. These risks make prostaglandin analogs a hot topic and pretty controversial in the world of lash enhancement. So, it’s worth thinking twice before diving in!


Phthalates, used in cosmetics like lash serums, are a bit shady. These chemicals mess with your hormones, which can lead to serious reproductive and developmental issues down the road. Bottom line: they're trouble, so it's smart to avoid them for your own good!

Safe Alternative - Natural Lash Serum

Natural lash serums use plant-based ingredients to promote lash health and growth. These serums avoid the harmful side effects associated with prostaglandin analogs, providing a safer alternative for consumers.


General Safety Tips

Reading Labels

Understanding product ingredients is crucial for safety. Always read the labels of lash extension products to identify harmful ingredients. Pay attention to the ingredients that come on top of the list, as typically, they’re provided in such a way to display from most to least amount. Look for cruelty-free products to ensure safer choices.

Consulting Professionals

Make sure to consult with certified lash technicians who really know what they use. Their advice can help you make smart choices and lower the chances of any bad reactions. And if you are a professional, share  your knowledge with your clients, so they can choose the best aftercare for themselves.



It's super important to use safe products for lash extensions. By avoiding harmful ingredients and choosing safer options, your clients will enjoy gorgeous lashes and return for more. Always prioritize product safety, give advice, and recommend them stick to good aftercare routine to ensure their lash experience is both beautiful and safe.
