Eyelash Extensions Allergies: Must Read

Eyelash Extensions Allergies: Must Read. No matter how careful we are, this thing happens. You might wonder even to the clients you’ve been servicing for years. An allergic reaction to eyelash extensions is similar to other contact allergies, also known as contact dermatitis.

Clients who develop an allergic reaction to their eyelash extension adhesive will typically experience swelling and itching of the eyelids. They usually show up within the first 72 hrs of completion of a lash service.

Reactions to eyelash extensions are rare reactions to the lashes themselves. Rather, reactions occur when the adhesive is uncured, developing in response to either the carbon black used to pigment the adhesive.

How to prevent an allergic reaction? I would say less is more. Start using minimal adhesive and just add up if needed. Make sure that with each lash, you’re not getting too close to the lash line, staying at least 1mm away is a good rule of thumb.

A person may have an allergic reaction in their eyelid or eye. Where the allergic reaction occurs affects the symptoms that a person may experience.

Allergic reaction in the eyelids

A person with allergic blepharitis may experience:

  • tearing
  • irritation
  • redness
  • itchiness
  • swelling

The allergic reaction may occur on both eyelids, but it might be worse on one of them. It can happen soon after the application of the eyelashes or take several hours or days to occur.

Allergic reaction in the eyes

Allergic reactions in the eyes can cause various symptoms, such as:

  • redness
  • irritation
  • itchiness
  • watery eyes


In cases of mild reaction, a person may be able to treat the symptoms at home. They can try:

  • eye drops
  • cold compresses
  • antihistamines
  • hydrocortisone cream or ointment

It is also important to resist the temptation to rub the eyes if they are itchy. If symptoms are severe, a person should see their doctor for treatment. A doctor can assess the severity of the reaction and provide specific treatment for it.
