Sun care innovation is moving beyond UV filters. Film-forming polymers are becoming an important part of how sunscreen brands improve SPF performance, water resistance, and product feel without necessarily increasing UV filter concentrations.
Research cited in the innovation landscape found a 61.58% increase in SPF and a 43.84% improvement in UVA protection using a co-assembled film-forming system compared with the same filter system without it.
Our analysis of sun care film-forming innovations from 2021–2026 examines the technologies, patent activity, supplier strategies, and formulation approaches shaping this shift, including where new opportunities and competitive risks are emerging.
Key Signals Reshaping Sun Care Innovations
