Usage, safety and formulation details
Mechanism of action
Its conjugated molecular structure absorbs ultraviolet energy. Photostability is useful, but complete sunscreen performance still depends on the formulation.
Sources: 1, 2, 3Potential adverse effects
Some users experience irritation, contact allergy or eye stinging; select a tolerated finished sunscreen rather than abandoning sun protection.
Sources: 1, 2, 3Formulation considerations
