Dermatologists agree: when it comes to washing your face or body, lukewarm water is best.
While both hot and cold water have their occasional benefits, extreme temperatures can damage the skin, especially if you have sensitive or acne-prone skin.
According to the magazine Health, the American Academy of Dermatology (AAD) recommends using lukewarm water to gently cleanse the skin without stripping it of natural oils or causing irritation.
The ideal routine involves cleansing twice a day with lukewarm water and a gentle, skin-type-appropriate cleanser.
What Cold Water Can (and Can’t) Do for Your Skin
Occasionally rinsing your face with cold water may offer some short-term benefits:
Boosts blood flow to the skin
May tighten pores for a firmer appearance
Can help reduce inflammation and soothe puffiness
Might temporarily reduce oil production, especially helpful for acne-prone skin
However, cold water isn't ideal for removing dirt, oil, or makeup. It may leave residues behind and make your cleansers less effective.
Extended exposure to cold water may also irritate sensitive skin and weaken the skin barrier, particularly in low temperatures (below 40°F / 4°C).
Why Hot Water Can Be Harmful
Hot water—especially above 107.6°F (42°C)—can feel relaxing but may actually harm your skin:
Strips natural oils, causing dryness and irritation
May worsen acne by clogging pores as the heat causes pore linings to constrict
Can damage the skin barrier, making skin more sensitive
May exacerbate wrinkles and signs of premature aging with long-term use
That said, targeted heat (like a brief 5-second application of 120°F / 49°C) has been studied for relieving itchiness in certain skin conditions like eczema.
However, this method is not suitable for general skincare use and requires more research.
When it comes to skin health, lukewarm water is the clear winner.
While hot and cold water have their uses in specific situations, extremes can compromise your skin’s barrier, hydration, and overall balance. A consistent routine with the right temperature can help maintain healthy, glowing skin.
