IvyBlock® is a safe, effective, non-allergenic over-the-counter lotion that really works, really well. And, it's as simple to use as sunblock. Just rub it on your skin before you go outdoors and you're protected for hours.

The secret ingredient? It's Bentoquatam, a patented substance that actually absorbs urushiol-the incredibly irritating oil that's the most common cause of allergic contact dermatitis in America-before it irritates the skin.
