Aegis Beauty Solutions examines an underappreciated class of ingredients — SPF-boosting agents — and demonstrates how these agents function synergistically with primary UV filters to achieve more efficient, stable, and safe photoprotection systems.
ABSTRACT
The pursuit of higher sun protection factors (SPF) and broader spectrum protection has evolved beyond simply stacking of ultraviolet (UV) filters. Contemporary sunscreen research increasingly emphasizes advanced formulation strategies aimed at maximizing the performance of individual protective components. This article examines a critical underappreciated class of ingredients — SPF-boosting agents, also referred to as synergists. By systematically outlining five key mechanisms of action — namely, film formation, dispersion optimization, light scattering, biological activity modulation, and photo stabilization — this paper demonstrates how these agents function synergistically with primary UV filters to achieve more efficient, stable, and safe photoprotection systems
Growing consumer awareness of photoaging and skin cancer has driven an increasing demand for sunscreen products that offer high levels of protection, superior sensorial performance, and a strong safety profile.1
