ISDIN UV Mineral Brush SPF50+ is a portable brush-on facial sunscreen that provides high protection against UVA/UVB rays and blue light. It features 100% mineral filters and anti-pollution ingredients, offering convenient on-the-go application that can be used over makeup while adapting to your skin tone. The product should be applied by removing the rubber protector and making circular movements with the brush until minerals begin to flow. Before facial application, tap the brush twice on hand to avoid excess product. Apply in circular motions across face and exposed areas like neck and hands. For best protection, apply to dry skin before sun exposure and reapply every 2 hours as needed. Do not wet the brush as it could damage the powder formula. Contains key ingredients like titanium dioxide, zinc oxide, and light-reflecting particles that help visually reduce the appearance of wrinkles and pores.
