When you engage in beauty courses online, you get many of the skills you need to become the best possible eyelash extension technician you can be. Of course, creating beautiful lashes for your clients is your primary role, but that needs to be backed up with excellent aftercare, which involves advising your customers about any potential side effects.

You don’t necessarily have to have done a bad job on your client’s eyelash extensions for side effects to occur, as there are other factors at work. Skin sensitivity and people not being able to stop touching their eyes are just two of the reasons why complications might result, so as a professional, you need to know what they are so to provide the right guidance.

Possible Side Effects From Lash Extensions

People who take beauty courses online learn that while lash extensions can make a person look simply amazing, they do come with some risks - which is why clients should always use professional services rather than doing a DIY job. To begin with, 100% sterile tools need to be used at all times to prevent any infection from being transferred.

Then there’s an errant adhesive that can cause problems, with the glue vapour itself also able to irritate the eyes. When lash adhesive gets where it’s not supposed to be, it can cause a minor reaction like watery eyes or a serious burn in more severe cases. However, it’s not just the eyes you’ve got to worry about, as the skin can also be irritated. 

Knowing What Signs to Look For

Another part of dealing with the side effects we’re talking about is understanding what the symptoms look like when they happen. Typically relating to an allergic chemical reaction or infection, beauty courses online teach us that problems arising after extensions have been attached will usually manifest within two or three days, and they include:

  • Red or bloodshot eyes
  • A burning sensation around the eyes
  • Persistent itching
  • General eye discomfort
  • Rashes in the eye area
  • Mild to severe swelling
  • Eyelid inflammation or redness

Everyone has different reactions and sensitivities to certain chemicals, whether talking about the products that are used to attach eyelashes or remove them. Benzoic acid, cellulose gum, formaldehyde and geraniol represent just a few of them. 

It’s, for this reason, that beauty courses online tell us that patch testing before lashes are installed is the best way to proceed with new clients. Taking steps like these will protect your customer and your reputation as a professional.
