Temporary false lashes are applied with temporary lash glue, and are not designed to be worn when showering, sleeping or swimming. The lashes come as individuals, clusters, and most commonly, lash strips. The magnetic lashes work by placing the magnetic false lash between one’s eyelashes, thereby sandwiching in natural eyelashes with the magnetic eyelashes. Due to the nature of magnets, there has been a lot of concern regarding this beauty trend. However magnetic eyelashes pose no threat to eye health, as the magnets used are too small to be considered hazardous. Some even argue that magnetic eyelashes are safer than the regular false eyelashes, that require glue. This is based on the fact that lash glue often contains ingredients like the allergen, latex, or even harmful chemicals like formaldehyde, phthalates or ammonia.
