Lash Extension Allergies and Sensitivities: What You Need to Know

by Nancy Pham

Lash extensions are a game changer for anyone wanting fuller, longer lashes without the need for mascara. But like any beauty treatment, it is important to understand the potential risks. Allergies and sensitivities to lash extensions are uncommon, but they can happen. Knowing what to look out for and how to manage a reaction can make all the difference in keeping your eyes safe and your experience stress free.

 

What Is the Difference Between an Allergy and a Sensitivity?

A sensitivity is a mild and often temporary irritation. It might show up as red eyes, a slight itch, or watery eyes during or after a lash appointment. These symptoms usually settle down within a day or two and may not reoccur with future appointments.

An allergy, on the other hand, is a stronger immune response. This can cause symptoms such as swollen eyelids, tightness, itching, burning or puffiness that may last longer and worsen over time. Allergic reactions do not usually improve with repeated exposure and may even become more severe if you continue having lash extensions applied.

 

What Causes Reactions to Lash Extensions?

Most reactions are not caused by the lashes themselves but by ingredients in the lash adhesive. The main ingredient that can trigger a reaction is cyanoacrylate, which is used in all lash glues. Even glues labelled as sensitive still contain this bonding agent, although in smaller amounts.

Other possible triggers include

  • Fumes from the adhesive

  • Poor ventilation during application

  • Latex in some types of tape or gel pads

  • Improper aftercare that leads to build up or infection

 

How to Know If You Are Having a Reaction

If you notice any of the following symptoms after getting lash extensions, you may be experiencing a reaction:

  • Red or bloodshot eyes

  • Itching or burning around the eyes

  • Swelling of the eyelids

  • A tight or irritated feeling in the eye area

  • Watery or dry eyes that persist beyond the first 24 hours

Always contact your lash artist if you experience anything unusual. Never try to remove your lashes yourself, as this can make the situation worse and may damage your natural lashes or irritate your eyes further.

 

What to Do If You Have a Reaction

If you are experiencing mild symptoms, a cold compress and over the counter antihistamines may help ease discomfort. For more serious reactions, it is best to seek advice from your GP or a healthcare professional. You may also need to have the lash extensions professionally removed.

In some cases, lash wearers choose to stop getting extensions altogether or switch to alternatives like lash lifts.

 

Can You Prevent a Reaction?

While allergies cannot always be predicted, there are a few ways to lower your risk:

  • Book a patch test before your first lash appointment

  • Let your artist know about any past reactions to products or adhesives

  • Avoid having lash extensions applied if your eyes are already irritated or if you have hay fever or sinus issues on the day

 

Reactions to lash extensions are rare but possible. The good news is that most sensitivities are mild and manageable. By choosing a professional lash artist and following their advice, you can enjoy beautiful lashes while keeping your eyes healthy.
