Is UV Resin Harmful To The Human Body?

UV light resins are non-toxic and are polymers.
UV resin is composed of polymer monomers and prepolymers, both of which are highly irritating/corrosive/toxic.
After UV curing, it becomes a polymer and is non-toxic.
That is to say, it is toxic before curing and non-toxic after curing.
But I personally think that chemicals definitely have an impact on the body. This is for reference only.
