Eyelash extensions allergic reactions can be experienced by clients either during or after lash extensions application.

However, allergy due to eyelash extensions application is very rare and is not an indication of serious health problems.

In this article, I will focus on providing information about the causes, symptoms, treatments, and preventions of allergy due to eyelash extensions filling.

So, let's jump into the main points.


    What is Allergic reaction in the Place?

    An allergic reaction is an immune system response to any foreign chemicals or substances that our body immune system thinks or suspects that they might compromise or cause harm to our body.

    The substances or chemicals that have the potential to cause allergic responses are called allergens. They include but not limited to foods, formalin, lash extensions primers and glue, talc in powder, pollen grains in plants, essential oils and so many of them.

    And one thing about allergy is that, just because you are allergic to one type of allergens that does mean you are allergic to all types of allergens.

    For example, you may be allergic to eyelash extensions primer but you will not be allergic to lash extensions glue.

    In this case, as lash extensions technicians, you only need to change the lash extensions primer with one that is suitable for your clients.

    Differences Between Eyelash Extensions Allergic Reactions And Irritation

    As a lash extensions technician or stylist, it is important to know the differences between the allergy and irritation.

    This helps you understand what is really disturbing your client when the client confront you with symptoms.

    The two conditions look like they are the same, however, they are not.

    Where allergic reactions are immune system responses due to allergens, irritation is a feeling of discomfort or pain due to irritants. Irritants are substances or chemicals that have the potential to cause irritation.

    Irritation can be triggered by stress due to eyelash extensions filling or anxiety from the client.

    Symptoms of allergy

    Symptoms of eyelash extensions allergy can be classified into two types.

    These are:

    • Simple symptoms
    • Chronic or severe symptoms

    The simple symptoms include:

    • Eye tearing
    • Redness of eyes
    • Skin sensitivity
    • Swollen eyes
    • Headache

    The severe symptoms include:

    • Rashes
    • Eczema
    • Contact dermatitis
    • Hives
    • Burning sensation
    • Severe itching

    Symptoms of irritation

    Sometimes, your client may experience irritation if the client has an underlying medical conditions such as irregular menstrual cramps, reduced sex drive, hair loss, headache, and fever.

    Common symptoms associated with irritation are sweating, fast breathing, annoyance, confusion, heart racing and sometimes pain.

    What Causes Eyelashe Extensions Allergic Reactions?

    Eyelash extensions allergic reactions can be caused by lash extensions primers, lash glue, and low quality of the lash extensions salon.

    As a lash extensions technician, it is important to know that allergic reactions are not typical because of eyelash extensions, but allergic reactions occur due to the synthetic chemicals in lash extensions primers and glue.

    Most if not all the adhesive glue that is used for binding the eyelash extensions to the natural eyelashes contain cyanoacrylate. And this chemical is responsible for almost all forms of lash extensions of allergic reactions.

    The cyanoacrylate is a colorless liquid chemical with adhesive property and is because of this property, the chemical becomes popular among eyelash extensions lovers and other stylists.

    It has been widely used to connect tissues during surgical operations, and more commonly to connect eyelash extensions to the natural eyelashes.

    However, one study showed that the short form of cyanoacrylate quickly dissociates giving out a harmful toxic chemical, which causes allergic responses.

    And this is the most common form of cyanoacrylate that is widely used in eyelash extensions glue.

    In this study, long forms of cyanoacrylate were found to cause less harm.

    During degradation or curing time of cyanoacrylate fumes and heat are released, and this heat can be perceived by the client's system as a warming skin sensation, especially if the client's skin is sensitive skin. This increases the risk of allergic reactions.

    And one study also showed that heat generation due to cyanoacrylate can cause burning sensation to patients.

    During lashing, this heat generation can be seen in the form of fumes or vapors.

    Another that can be found in lash glue is the carbon black, which is used to color the lash glue. This was also found to cause allergic responses with symptoms such as burning sensation, eye tearing, and swelling, especially to clients with compromised skins

    Applying eyelash extensions too close to the eyelids can also increase the chance of lash glue getting into the eyes, and thereby causing eye tearing, burning sensation, and redness of eyes.

    Lashing or lash extensions filling in a non-ventilated area can also be a major contributing factor for causing eyelash extensions allergic reactions.

    The ventilated area is an area with low oxygen. Low oxygen in an area can lead to oxygen tension which is medically known as hypoxia.

    Low oxygen causes less oxygen supply and low blood flow to the brain and other important organs of the body.

    Since the brain and other organs of the body solely depend on oxygen supply and blood flow, this condition puts your body into a state of shock, which is also a form of allergic reactions.

    This condition of low oxygen supply and blood flow can stimulate you to release chemicals called histamines, and histamines are the ones responsible for swelling, itching, and burning sensation.

    Use a clean cotton bud to apply the oil and remove the eyelash extensions and lash glue.

    This can help lower the inflammation, itching, and other possible injuries that might result before the client sees a doctor.

    Use Hydrocortisone cream

    Hydrocortisone cream is also a good anti-allergy that can provide immediate relief for inflammation, burning sensation, and itching.

    Cold compress

    Cold compress is the application of local cold on the area affected by allergy. This is done to store the body back to normal balance by calming down the body immune system and blocking the effects of inflammation.

    Immediately remove eyelash extensions

    When you notice your client is developing a sign of discomfort, eye tearing, and having redness of cornea, stop filling the eyelash extensions and advise the client to see a medical doctor.

    If it is after you applied the lash extensions, the client started experiencing allergy, then immediately remove the eyelash extensions. There are some clients that will insist to have the eyelash extensions despite having these health problems, do not listen to them and advise them with the potential side effects of allergic reactions.

    Because, if you leave the eyelash extensions, that can lead to a severe form of allergy such as ad blindness, rashes, contact dermatitis, hives and so on.

    Tell them that once you are allergic to a certain chemical or substance, it is important to avoid contact with that substance.

    Use of chamomile essential oil
