Vitamin K, (In German call koagulation) has long been used to promote blood clotting and prevent bleeding, particularly in
cases of aspirin poisoning or blood-thinner overdose. It’s also a favorite among plastic surgeons, who use large doses on their patients to prevent post surgery bruising.
Now these benefits are accessible to the general public as well. Research shows that applying vitamin K topically can prevent and heal bruising from laser surgery and fade away bruises, even those occurring from purpura senilis.
