Developments: 5. Medical experts, including dermatologists and ophthalmologists, have issued warnings regarding the health risks associated with eyelash extensions. Initial warnings highlighted that improper hygiene or unsuitable adhesives used in silk eyelash extensions can lead to eye irritation, allergic reactions, blepharitis, and the growth of Demodex mites. Specialists identified specific risks such as inflammation of the eyelids and corneal irritation, which can cause symptoms like photophobia and blurred vision. Recent clinical observations, including input from dermatologist Elise Taniguchi Muller at the Hospital dos Olhos de Blumenau, reinforce that adhesives can cause significant discomfort and corneal irritation. Furthermore, the artificial lashes can hinder hygiene, allowing dirt, bacteria, and mites to accumulate, contributing to redness and intense itching. Scientific research has further detailed these complications. Studies published in Cornea have linked extensions to conditions such as keratoconjunctivitis and allergic blepharitis, often stemming from adhesives or removal products. Research in Contact Lens and Anterior Eye has identified short-term changes in tear film stability and stress on the corneal epithelium immediately following application. Expanding on these risks, Dr. Christos Pitsas, President of the Hellenic Ophthalmological Society, notes that false eyelashes and extensions can cause or exacerbate eyelid irritation and inflammation. This is particularly relevant to blepharitis, a condition affecting 30% to 50% of ophthalmology patients, which is often linked to dry eye syndrome. New research presented at the European Society of Cataract and Refractive Surgeons (ESCRS) congress has further identified links to Meibomian gland dysfunction. A study led by Dr. Tetiana Zhmud from the National Pirogov Memorial Medical University found that 85 percent of women who had received extensions at least ten times showed signs of this dysfunction, as adhesives can physically block the glands responsible for the oily layer of tears. ## Timeline ### 2026-09-19: Eyelash extensions linked to eye health risks in new study A study presented at the ESCRS congress warns that frequent eyelash extensions can cause Meibomian gland dysfunction, eye irritation, and the presence of microscopic mites on the eyelids. 2 sources. https://clstr.news/cluster/eyelash-extensions-linked-to-eye-health-risks-in-new-study ### 2026-09-19: Blepharitis risks and the impact of eyelash extensions Medical experts warn that blepharitis affects up to 50% of ophthalmology patients and can be exacerbated by the use of false eyelashes and extensions. 2 sources. https://clstr.news/cluster/blepharitis-risks-and-the-impact-of-eyelash-extensions ### 2026-09-15: Eyelash extensions pose potential risks to eye health Eyelash extensions can cause eye complications like keratoconjunctivitis and tear film instability due to adhesives.
