Hidden Risks of Eyelash Extensions to Eye Health

Eye specialists have warned that the application of eyelash extensions may increase the risk of Demodex mite accumulation around the lashes, potentially causing itching, redness, irritation, skin flaking, and blurred vision. A study conducted by ophthalmologist Tetyana Zemod and her team found that these mites were present in 24 out of 25 women who regularly undergo eyelash extension procedures, representing a prevalence of 96%. The study included 345 women aged 16 to 28. Half of the participants reported undergoing extensions every three to four weeks, approximately 17 times per year, while 48% reported experiencing discomfort, redness, or itching following the procedure. Another examination revealed that 85% of women who had received at least ten eyelash extension treatments suffered from blocked eyelid glands or reduced secretion of the oils necessary to maintain eye moisture. Demodex mites are common among adults and typically fall off naturally from the lashes without causing problems. However, large accumulations can lead to eye infections. Researchers believe that eyelash extensions may provide an environment conducive to mite reproduction, as dead skin cells and glue residue accumulate around the lash base, and extensions may also hinder the natural removal of dead mites. Professor Sorcha Ní Dhubhghaill, chair of the Cornea Committee at the European Society of Cataract and Refractive Surgeons, noted that detecting the mites may become more difficult for extension users, as the adhesive is applied near the area where characteristic waxy “cuffs” typically appear—these cuffs are deposits and scales that accumulate around the lash roots and serve as indicators of Demodex presence. Zemod emphasized the importance of eyelid hygiene and vigilance regarding warning symptoms, and recommended that women who regularly undergo eyelash extension treatments clean their eyelids twice daily using a gentle cleanser and a dedicated lash brush.
