protective layer
Defense against damage
A protective layer is any covering that shields what lies beneath from damage, contamination, or deterioration.
The term appears across contexts: a protective layer of sunscreen, a protective layer of varnish, the ozone layer as Earth's protective layer against ultraviolet radiation.
In figurative use, emotional defenses may form a protective layer: She developed a protective layer after years of criticism.
