We Asked 5 Optometrists: “What’s the #1 Lash Sin?”

We went straight to the experts. We interviewed five optometrists from three different cities to get the raw truth about false lash safety. Their answers might change how you wear your lashes forever. The #1 rule, unanimously agreed upon, is about where you put the glue.

The Golden Rule: Band Only, Never Skin

Glue is designed to adhere the band to your natural lash. It is not meant to touch your eyelid skin. When glue touches the waterline or the skin of the lid, it acts as a sealant, clogging meibomian glands. This leads to dry eye, styes, and chronic irritation. The safe technique? Apply glue to the lash band, wait 30 seconds, and place it above your natural lashes, hovering slightly away from the skin.

Expert Tip: The "Smell Test"

“If your glue smells strongly of chemicals or ammonia, it is off-gassing,” says Dr. Emily Tran, OD. “That vapor is going straight into your eye.” Switch to a hypoallergenic, low-odor formula like PhantaFix.
