That review covers 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. No filter category should be presented as universally safer, gentler, or more environmentally responsible without relevant evidence and market context.
