No, hot water does not tighten skin. In fact, hot water can have the opposite effect, potentially drying out skin and making it appear less firm. While hot water opens pores, it's the cold water that's associated with a temporary tightening effect on the skin. This is because cold water constricts blood vessels, leading to a temporary feeling of skin firmness. Several sources confirm that cold water, rather than hot water, helps tighten the appearance of skin.
The Effects of Hot vs. Cold Water on Skin
- Hot Water: Opens pores, can dry out skin, potentially worsening the appearance of wrinkles or sagging. Several sources, including the National Institute on Aging, advise against hot baths or showers as they can exacerbate dry skin.
- Cold Water: Temporarily constricts blood vessels, leading to a tightening effect on the skin. This effect is temporary and only affects the superficial layer of the skin. Multiple sources, including Healthline and Kiehl's, highlight the temporary skin-tightening effect of cold water.
Misconceptions about Hot Water and Skin Tightening
It's important to differentiate between the feeling of tightened skin and actual skin tightening. Hot water may temporarily feel like it's tightening the skin due to the warmth, but it doesn't produce lasting changes in skin elasticity. Long-term skin tightening requires different methods, such as cosmetic procedures or targeted skincare routines.
Several references mention the benefits of cold water for skin tightening, while none support the claim that hot water tightens skin. In fact, some sources warn against using excessively hot water as it can lead to dryness and other skin issues.
