FAQ # 2 - How exactly does this product work?

The Insect DEFEND Patch is a transdermal, patch that slowly releases Thiamine (Vitamin B1) into the dermal skin layer of the body, becoming effective in 2 hours. The Thiamine (Vitamin B1) is then slowly released through the skins pores through sweat glands. Combined with the body’s own chemistry it produces an invisible, odorless ‘shield’.
