Ever wonder if washing your face with cold water benefits your skin? While cleansing the skin with lukewarm water is best, experts say cool or cold water can help the skin in a few ways. Here are some of the top reasons someone may want to wash using cool or cold water: (1) It can help reduce puffiness around the eyes, especially in the morning upon waking. (2) Washing with cool water may help with acne-related irritations. (3) Cold water causes vasoconstriction, temporarily giving the skin a less inflamed and brighter appearance. However, washing your face with cold water also carries a few possible downsides. For example, experts say cold water may not cleanse the skin of pollutants and bacteria as effectively as washing with warm water. It may also cause pores to contract, trapping grime and oil and making cleansing less effective.
