Can washing your face with frozen water close pores?

Pores do not shrink or expand when heated!

Heat relaxes muscles, while freezing causes them to contract. However, since pores have no muscles at all, they will not expand due to contact with warm/hot water, and washing your face with cold water will not shrink the pores. Which water temperature is best for cleansing?

1. Wash your face with cold water (4-15°C)❄️

Frozen water will cause the skin's arrector pili muscles to contract, which will temporarily block some pores, creating the illusion of shrinking pores. When the skin temperature returns to normal, the pores will also return to their original appearance.

The pores may be blocked due to the contraction of the arrector pili muscles, making it difficult to clean the dirt in the pores and affecting the cleaning efficiency.

Too low water temperature may also irritate the nerves of the skin, causing a tingling sensation.

2. Wash your face with hot water (≥ 40°C)♨️

Hot water can effectively soften the oil and dirt on the skin and improve the cleaning efficiency, but it can also easily wash away the sebum film that protects the skin, leaving the skin dry and uncomfortable.

High temperature will also stimulate the expansion of capillaries in the skin, making the skin prone to redness, especially in people with sensitive skin.

3. Wash your face with warm water (~ 30°C)🚿

Dermatologists recommend washing your face with warm water (the skin will only feel slightly warm) every day. It can effectively soften and remove excess oil, keep pores clear, and maintain a healthy skin barrier.

Cleansing is the first step in skin care. If you are used to washing your face with super hot water on weekdays, you might as well try lowering the temperature tonight. It actually feels just as comfortable and can prevent your skin from drying out.

Change your face-washing habits, starting with the water temperature.
