Vitamin K Serum is very popular in Korea known
as "bruise cream" or "detox cream."
Bruises result from some type of trauma or injury to the skin that causes blood vessels to burst. Bruises usually go away on their own, but you can take steps to lessen the pain and reduce the visibility. Applying ice immediately after the injury to reduce blood flow around the area can help. Cooling the blood vessels can reduce the amount of blood that leaks into the surrounding tissue. This can prevent the bruise from being as apparent and reduce swelling. so people actually use these creams to help with blood circulation and depuff the face post treatments even if you dont have visible bruising. also these creams are popular for dark circles and eye bags!
Vitamin K is an essential nutrient that helps with blood clotting. Vitamin K cream was shown to reduce the severity of bruising after laser treatment in a 2002 study.
Gently rub vitamin K cream onto the bruise or on the concerned area at least two times per day.
Bruise creams are meant to be applied after toner, before essence!
