“The risks of eyelash extensions are not only an allergic reaction to the glue, but erosion of the inner surface of the eyelid,”
– Dr. Orly Avitzur, M.D.



Day-wear extensions take up to 20 minutes to apply and permanent extensions take up to 2 hours. The process is long and expensive.

Causes Lash Loss

Eyelid inflammation from overuse of eyelash extension can cause eyelashes to get inflammation and can fall out, known as Blepharitis. This can be permanent.


As a minimal, lash extensions can harbour extra bacteria, increasing the risk of lid infections like styes and eye infections like bacterial conjunctivitis.

Infestation of Lice

Improper or overuse of eyelash extensions can result in developing Demodex and parasites, which is the medical term for lash lice and mice… Ewww. Let’s move on.

Permanent Damage

Allergies, infections, trauma and improper use can damage permanently. Overuse of heavy extensions can cause long-term traction alopecia, which is a permanent lash loss condition.

Doctors Agree

Lash lice, Demodex, is becoming a common problem for extension users. It’s recommended to stop using extensions or take regular breaks from wearing them. Lashfactor Pharmacists agree, too.

Unwanted bacteria can build up in day-wear and permanent eyelash extensions, which can cause unwanted infections and infestations of parasites. Eyelashes are in close proximity, an important sensory organ, which should always be taken care of. Any foreign object or fluid applied to this area should be hypoallergenic & 100% sterile for maximum safety.
