Two days after a lash extension service, a client calls the salon reporting itchy, red, and swollen eyelids that were not present immediately after the appointment. What most likely caused this reaction?
- AAn immediate reaction to eye makeup applied by the client
- BNormal shedding of natural lashes
- CA delayed allergic reaction to the cyanoacrylate adhesive
- DOverexposure to sunlight after the appointment
Show answer & explanationAnswer & explanation
Correct answer: C. A delayed allergic reaction to the cyanoacrylate adhesive
Allergic reactions to cyanoacrylate lash adhesive can be delayed, sometimes appearing 24-72 hours after exposure, rather than immediately. Symptoms such as itching, redness, and swelling of the eyelids indicate a hypersensitivity reaction, and the client should be advised to have the extensions removed and see a physician if symptoms persist or worsen.
Why the other options are wrong
- A. Makeup reactions typically occur at time of application, not two days later as a new onset.
- B. Natural lash shedding does not cause itching, redness, or swelling.
- D. Sunlight exposure is not a typical cause of sudden delayed eyelid swelling after lash services.
Delayed Adhesive Allergy
An allergic reaction to lash adhesive that may not appear until 24-72 hours after application, presenting as itching, redness, and swelling.
- Caused by sensitivity to cyanoacrylate in adhesive
- Can occur even after multiple prior uneventful services
- Client should remove extensions and seek medical care if severe
Memory trick: The itch doesn't always come quick — allergies can be a late trick.
