This concealer requires no complex setup. Simply twist the cap to open, pull out the doe-foot applicator, and apply directly to your skin. Compatibility: It is specifically designed to pair seamlessly with the Armani Power Fabric foundation for a cohesive, full-face look. However, it can also be used with other foundations or on its own for targeted correction. Care: To maintain the product's quality and hygiene, always secure the cap tightly after each use. Store the concealer in a cool, dry place away from direct sunlight. Avoid touching the applicator directly to your fingers or other surfaces to prevent contamination. Regularly clean the area around the bottle opening to prevent product buildup.
