Is 3D resin toxic after curing?

Why is my UV resin tacky after curing?
Tackiness or stickiness may be noticed on the surface of some ultraviolet (UV) light-curable adhesives and coatings. This phenomenon, known as oxygen inhibition, is the result of atmospheric oxygen inhibiting the cure on the surface layer of the polymerizing material.
Is cured resin safe on skin?
Cured resin is not toxic because its photo-polymerization is complete already and the plastic becomes inert. Firstly, this means that the resin material hardens and solidifies completely, so no toxic chemicals can leak from it anymore. This makes it safe for the skin.

Why is resin cancerous?
