The Integra LifeSciences Corporation Unna Boot Primer is a zinc oxide-based medical dressing designed to protect the skin underneath Unna Boots. As an antiseptic and antibacterial agent, zinc oxide inhibits microbial growth and helps prevent skin maceration, irritation, and infection. The non-adhesive primer is easy to apply directly to the skin, providing a protective barrier that reduces friction and prevents further damage. Ideal for wounds requiring support, such as venous stasis ulcers, cellulitis, and edema, the durable and long-lasting primer ensures extended protection for up to 24 hours. The convenient roll format allows for quick and simple application, making it a suitable dressing for various wound types. Contraindicated for open or infected wounds, the primer should be used with caution and discontinued if any irritation or sensitivity occurs.
