photoprotection

This term is primarily used in scientific, dermatological, and pharmacological contexts. It describes a technical process of shielding biological tissues or chemical structures from radiation-induced degradation, carrying a clinical and objective tone rather than a casual one.

As an uncountable noun, it refers to the general concept or the state of being protected. It does not typically take a plural form, as it describes a systemic property or a protective mechanism rather than a discrete object.
