A high percentage of individuals who frequently use eyelash extensions may be harboring a microscopic mite infestation that can lead to eye irritation and potentially blurred vision, according to new research.
The study, presented at the 44th Congress of the European Society of Cataract and Refractive Surgeons (ESCRS), found that 96 percent of women who regularly undergo the beauty treatment were infested with Demodex mites.
These microscopic arachnids, known as Demodex folliculorum, are common and typically do not cause harm. However, they feed on dead skin cells and oils, which can accumulate in the dried glue used to attach synthetic eyelash fibers. The extensions can also trap these mites, preventing their natural shedding and leading to overpopulation.
Researchers surveyed 345 women aged 16 to 28. Half of the participants reported getting eyelash extensions every three to four weeks. Approximately 48 percent of these women experienced discomfort, redness, or itching after the procedure.
Using a technique called meibography, which analyzes the oil-producing glands beneath the eyelids, researchers found that 85 percent of women who had received at least ten eyelash extension treatments had blocked glands or insufficient oil production to keep their eyes hydrated.
Microscopic examination of eyelash samples from 25 regular users revealed Demodex mites in 24 of them. Of these, 18 women also showed symptoms such as itching, irritation, redness, swelling, scaly skin, and sticky eyelashes.
This proliferation of mites can irritate eyelash follicles and block oil glands, a condition known as demodicosis, which can result in painful eye infections, inflammation, and distorted vision.
Experts noted that the adhesive used in eyelash extensions can also obscure the signs of mite infestation, such as "collarettes" – waxy rings made of mite debris, eggs, and skin cells – which are typically visible around the base of natural lashes. The glue can make these tell-tale signs harder to detect.
Dr. Tetiana Zhmud, an ophthalmologist at the National Pirogov Memorial Medical University in Ukraine who led the research, emphasized the importance of good hygiene and seeking timely assessment for any concerning symptoms. She recommended that individuals who use eyelash extensions clean their eyelids twice daily with a gentle cleanser and a lash brush.
