If you experience any eye irritation while wearing eyelash extensions, book an appointment with your local GP or dermatologist so they can diagnose the problem. If you do have Demodex, Dr. Green said they're likely to tell you to apply petroleum jelly to your eyelids and let it sit for two hours, followed by 1-percent permethrin shampoo for 10 minutes. You wash this off, and do this treatment twice a day. If they don't advise this course of treatment, they may prescribe an ointment.
Ultimately, prevention is the best treatment, so keep your lashes clean and, as Dr. Shotter said, "don't be afraid to take a break from extensions every now and then."
