Preparation and finishing
Luxury setting sprays: makeup wear and final finish

Reading wear claims in their context
An advertised wear duration reflects a claim assessed under particular conditions rather than an identical guarantee for every face. Heat, perspiration and rubbing influence actual use. Compare the objectives too: limiting transfer, preserving a matte appearance and resisting water are related considerations but are not strictly equivalent measures of performance.
Finishing with a controlled application
Spray at the distance and with the precautions specified for the formula, then let it dry without unnecessary rubbing. A mist cannot consistently correct incompatibility between layers already applied. To assess its usefulness, keep the makeup look comparable between trials and observe the areas where wear genuinely presents a practical difficulty.
