Yes. We use Medical-Grade Bio-Silicone combined with our RN068 Suspension Breathable Patent to enhance comfort during extended wear. This creates a micro-ventilation layer between the skin and the adhesive, helping reduce heat buildup, moisture accumulation, and sweating-induced slippage while improving overall breathability. This commitment to skin-friendly performance is reflected across our product range. For example, our Waterproof Boob Tape Sweat-Resistant & Breathable for Invisible Support is made from breathable, hypoallergenic materials and is specifically designed for sensitive skin, pregnant women, and breastfeeding mothers. Its breathable structure helps wick away moisture and minimize irritation during long wear. Similarly, our Semi Adhesive Triangle Nipple Cover Nippies Silicone Lifts feature medical-grade skin-friendly adhesive, hypoallergenic properties, and a patented adhesive-free center design that avoids direct contact with the sensitive nipple area. The product is specifically described as safe for sensitive skin while providing reliable adhesion and comfort. In addition, RuiBra states that its core materials include medical-grade eco-friendly silicone and bio-based adhesives that are odorless and hypoallergenic, and the company provides biocompatibility and safety testing support to help customers meet product safety requirements.
