After mones have dried, do they leech out if app points are physically rubbed on something?

Would the mone lose effectiveness? And if I'm sensitive to the mone, would enough rub off that should make sure to wash the clothes or part of my body thoroughly that the app point rubbed off on?

mix ink and oil, apply it, let it dry, try it out

Along the same lines and somewhat related: When applying oils via dropper is it better to let the drop stay on the surface or is it better to spread it out? Wondering if having it cover more open surface area makes for better dispersion or keeping the drop and oil how they landed and let it dissipate that way.

No one has tested this under scientific conditions. To find what works best for you both you have to test it out yourself
