Start with the sunscreen direction you want—mineral, organic, combination, or tinted. Then review whether that direction suits the target market, product format, desired feel, package, testing plan, and available manufacturing route.
The review can cover filter permissions, combination rules, use levels, dispersion, processing, photostability, and finished-product objectives. It also considers white cast, greasiness, tack, dry-down, pilling, tint, fragrance, viscosity, packaging compatibility, and intended application amount.
UV-filter selection is one part of product development, not a standalone ingredient decision. No filter category should be presented as universally safer, gentler, or more environmentally responsible without relevant evidence and market context.
