Acne Invisible Patches

Our Acne Invisible Patch is a advanced hydrocolloid dressing designed for the targeted treatment of blemishes, pimples, and minor skin imperfections. This ultra-thin, transparent patch serves as a protective barrier that absorbs exudates (pus and oil), maintains a moist healing environment, and prevents external contamination or picking. Utilizing cutting-edge hydrophilic gel technology, these patches are essential for modern skincare routines, suitable for both daytime invisible wear and overnight intensive care.

The patch features a precision-engineered multi-layer construction comprising a medical-grade polyurethane (PU) film backing, a highly absorbent hydrocolloid adhesive matrix, and a protective release liner. The production process involves advanced solvent-free polymerization and precision die-cutting technologies. The core formulation utilizes a hydrophilic gel matrix optimized through response surface methodology, typically consisting of NP700 (8g), glycine aluminum (0.8g), glycerol (120g), kaolin (3.4g), and tartaric acid (0.3g) to achieve the ideal balance of adhesion, cohesion, and fluid absorption . The manufacturing process creates a compact three-dimensional network structure through cross-linked ionic bonds between Al³⁺ ions and carboxyl groups, ensuring the gel maintains structural integrity while absorbing impurities . Each patch undergoes rigorous quality testing for initial adhesion, peel strength (typically 1.0-2.0 N/cm), and moisture vapor transmission rate. Standard dimensions range from 10-14mm diameter for spot treatments, with beveled-edge options available for enhanced skin conformity and invisibility . Manufacturing occurs in ISO Class 7 (Class 10,000) cleanrooms with strict environmental controls to ensure product sterility and freedom from microbial contamination. Patches are available in various configurations including non-beveled (standard), beveled-edge (ultra-thin), and custom-printed designs featuring logos or decorative elements.

As a specialized OEM/ODM manufacturer with vertically integrated operations, we maintain strict quality control across the entire supply chain from raw material sourcing to finished product packaging. Our facility operates under ISO 13485:2016 certified quality management systems, with dedicated R&D laboratories for formulation optimization and rapid prototyping capabilities . We have invested significantly in automated production lines featuring precision rotary die-cutting, vision inspection systems, and high-speed packaging equipment, achieving production capacities exceeding 100 million units annually across multiple manufacturing hubs in Guangdong and Zhejiang provinces-China's leading regions for medical-grade hydrocolloid technology . Our technical team specializes in custom formulations including active ingredient incorporation (tea tree oil, salicylic acid, centella asiatica, or witch hazel extract) to provide additional anti-inflammatory and antibacterial benefits . With over 15 years of contract manufacturing experience, we serve major cosmetic and pharmaceutical brands requiring private labeling, custom packaging configurations (individual blister packs, zipper packs, or paper boxes), and comprehensive regulatory support for global market access . Our quality management system incorporates robust batch traceability, stability testing (validated 24-36 month shelf life), and post-market surveillance procedures aligned with international expectations for continuous improvement.
