It is very hard to tell the difference between eye irritation and an allergy because symptoms may look the same: red puffy eyes, itchiness, tightness, watering, burning sensation. The difference between the two is that irritants do not cause the immune system to react and, in most cases, irritation will go away after 24 hours and should get better as time passes. Allergic reaction may not appear until several hours or even days after exposure to the allergen, making it difficult to work out the cause of the problem.
Irritation may be the result of the fumes emitted while adhesives cure and solidify. Delicate areas of the body where the skin is naturally thinner, particularly the eyelids are most vulnerable to irritant reactions.
Good ventilation is imperative. Ideally fans and air conditioners should be directed away from the treatment bed and windows should be open all the times to allow free air circulation.
An allergy is the response of the body’s immune system to normally harmless substances known as allergens. The human body produces antibodies (or immunoglobin) to fight these allergens. The more your body is exposed to the allergen, the more severe the allergic reaction might be. Symptoms can affect the eyes, nose, throat, skin…
In order to develop an allergy, you have to be exposed to the allergen more than once and repeatedly. This means that clients, that have never had an allergic reaction when exposed to cyanoacrylate (main ingredient of the lash adhesives) before, may develop the allergy after sometime and have to stop getting eyelash extensions. While a small percentage of clients develop an allergic reaction, this allergy is not especially dangerous, and the symptoms will disappear once the lash extensions are removed.
Allergy might manifest itself again if the body is exposed to the same allergen (e.g. if eyelash extensions are applied). The body keeps a memory of the allergy once developed therefore the immune system will overreact in contact with the allergen again.
The main ingredient of lash adhesives is a cyanoacrylate which provides the glue with adhesive quality. Without cyanoacrylate, the extensions wouldn’t stick to the natural lashes. This ingredient is used in all eyelash adhesives, even those formulated for sensitive or allergic eyes. Eyelash adhesives containing cyanoacrylates are generally safe when used as instructed.
Cyanoacrylates cure when it comes in contact with water. This is where the room humidity plays a major part. Adhesive will cure faster in high humidity and vice versa. Once it is cured, it is harmless as unable to act as an irritant. Cured adhesive is waterproof to a reasonable extent too and can be washed with water to calm irritated skin.
In dryer season, the adhesive will take longer to cure therefore exposure to fumes and irritants is higher. So if regular clients returns to you with allergic reaction even though treatment safety were carefully followed; you need to take into account the customer’s health but also the environment and the time of the year.
Most clients won’t have a reaction to cyanoacrylate as long as the extensions are applied carefully and the adhesive doesn’t get in their eye or on their skin. However, in rare cases clients develop an allergy to this ingredient as explained earlier.
If there is any redness or itching after patch test, the client is considered high risk and lash extensions are not recommended. But as the amount of the adhesive is very small, patch test doesn’t guarantee that the client may develop an allergic reaction therefore, it is important to inform your client of any possible contraindications and allergies before the patch test.
Q-1: Do you experience seasonal allergy symptoms?
A-1: A client suffering from hay fever could easily mix up the symptoms such as red eyes and itchiness for being a reaction to the adhesive. Also as previously explained, a body which is already fighting an allergy might be more sensitive to the allergens contained in the adhesive. It is important to remind the customer to refrain from rubbing their eyes as this could make the symptoms worse and also damage their extensions.
Q-2: Do you schedule other beauty treatment for the same client on the same or following day?
A-2: Clients that attend more than one treatments are exposed to other irritants. For example, having hair coloured or nails done. Exposure to several irritants in a short period of time may trigger the body to have a higher sensitivity.
Q-3: Are you taking any prescription drugs?
A-3: Certain prescription drugs, when built up in the body, can create sensitivity to some harmful substances. Clients may want to refer to their drugs leaflets for contraindications.
Q-4: Have you recently had a cold or a flu?
A-4: A recent cold or a flu is a sign of a low immune system. As explained above, the body doesn’t produce enough antibodies to fight the allergens. Clients that have never had a reaction to cyanoacrylate before may have an increased sensitivity.
Ask how long the sensitivity has been lasting and what are the symptoms? Ask the client if they have been exposed to additional irritants. Ask about seasonal allergies if not done prior treatment. Advise to resist the urge to rub eyes or pick at lashes. Ask client to come in to remove the lash extension asap. In case of severe symptoms, advise the client to contact their doctor immediately.
