Some treatments require an obligatory patch test to check for any allergic reaction to the ingredients in the treatment. The patch test must be carried out at least 48 hours before a new treatment takes place with your therapist – so ensure you consider this when booking your appointment! Always make sure you tell your therapist about any known allergies you have, any medical conditions (including pregnancy or menopause) or medications you are taking when you book your appointment. This will allow them time to provide advice and check any product ingredients.
You may have had a patch test before, but each new therapist will need to do their own test. You might also need another test if you haven’t had the treatment for a while, if your medical conditions have changed or if the product manufacturer changes the ingredients.
I follow my suppliers’ recommendations for patch testing and will let you know when a patch test is needed. Recently, my eyelash extension supplier has changed their policy and do not insist on patch testing, this is due to research that applying a few lashes does not give a clear indication of whether or not a reaction will occur and that lash glue should never be applied directly to the skin. However, you should ensure that you understand the risk of a possible allergic reaction and if you would like a patch test this can still be arranged a minimum of 48 hours before your appointment.
For eyelash extensions a reaction is usually caused by an allergy to the ingredient cyanoacrylate that is in eyelash extension adhesive. Symptoms are typically swelling, redness and itching of the eyelids. You can become allergic at any time, sometimes after the first lash application or even months or years down the road. If you do react once, you will continue to react over and over again. If you do experience any irritation, you should contact your lash technician immediately. The lashes will more than likely be removed to stop the irritation and you may then need to contact your GP depending on the severity.
In addition to adhesives you could be allergic to other products used in the prep and procedure so as mentioned before always make sure you mention any allergies etc.
