FREQUENTLY ASKED QUESTIONS
Everything you need to know about SEAL
What is SEAL Hemostatic Spray?
SEAL is an FDA-cleared hemostatic spray designed to rapidly stop bleeding. It works by forming a gel barrier over the wound upon contact, instantly halting blood flow while promoting the natural clotting process.
How does SEAL work?
SEAL uses a proprietary formula that reacts with blood to instantly form a protective gel barrier. This barrier physically stops bleeding while simultaneously activating the body's natural clotting factors, providing both immediate and sustainable hemostasis.
Is SEAL safe to use?
Yes, SEAL is FDA-cleared for over-the-counter use. The formula is non-toxic and does not cause tissue damage. It has undergone rigorous testing to ensure safety and effectiveness in a variety of applications.
Can SEAL be used on all types of wounds?
