Eyelash extensions can look very natural when they are applied well, but they are not completely risk-free. Adhesive, work close to the eye, the weight of the extensions and maintenance can cause irritation, allergic reactions or weakening of natural lashes in some people.
What are the risks of eyelash extensions?
Eyelid allergy or irritation
Some glues and adhesives can contain or release irritating or allergenic substances. A reaction may cause redness, itching, tearing or swollen eyelids, sometimes several hours after application.
Irritation of the eye surface
Glue vapours, a poorly positioned pad or handling too close to the eye can cause burning, a foreign-body sensation, redness or watering.
Infection
Poor hygiene of equipment, hands or the eye area increases the risk of infection. After application, makeup and residue can also build up if lashes are not cleaned correctly.
Weakening or loss of natural lashes
Extensions that are too heavy, poorly isolated or pulled during removal can place traction on natural lashes. Repeated stress can contribute to breakage or premature shedding.
How can you reduce the risks?
- choose an experienced technician working in a clean environment;
- ask which glues and products are used if you have known allergies;
- avoid extensions that are excessively long or heavy for your natural lashes;
- never pull extensions off yourself;
- clean the lash line regularly and gently;
- seek prompt medical advice for significant pain, reduced vision, marked swelling or discharge.
Does a patch test rule out an allergy?
No. A test may provide useful information, but it cannot guarantee that a reaction will never occur. Allergy can also develop after repeated exposure to the same product.
Do you need breaks between sets?
There is no single rule for everyone. If your natural lashes become more fragile, the area feels irritated or remains sensitive, taking a break is sensible. The important point is not to hide a problem by immediately applying another set.
How should you care for extensions?
Hygiene remains essential. Follow your technician’s cleaning advice and avoid rubbing or pulling the lashes. Our eyelash hygiene guide covers the key steps.
What are the alternatives to extensions?
For a more intense look without extensions, use a lash curler and mascara. See our false-lash-effect mascara tutorial. If you are looking for daily care instead, our guide to choosing an eyelash serum explains how formulas differ.
