From personal experience of fleshing and eating and breathing, i would highly recommend a barrier lotion to protect your skin.
It is worth researching different types that are available to you in your area, but you will need to read any information on any products and make sure what kind of protection they give for what you intend to use said products for.

In giving love there is an equal grace.
Nor need one seek the aura in the face,
As love unveils the beauty of all things."
