Eye drops. We advise against using eye drops while wearing pre-glued lashes, because the liquid runs along the lash line and can weaken the bond. If you need them (prescribed drops or contact lens comfort, for example), wait at least 24 hours after applying the lashes so the bond has cured, then apply the drops carefully with your head tilted back and blot any excess away from the lash line rather than rubbing. Never stop prescribed eye drops on our account; just be aware the lashes may not last as long.
Contact lenses. Perfectly fine. Put your lenses in after applying the lashes, and take them out before removing the lashes.
Lash serums. Most serums are applied along the lash line and many contain oils or conditioning agents, so we recommend pausing serum while wearing the lashes and applying it between sets instead.
