Cold water tends to constrict pores, so those with oily skin should avoid washing their face with it. Cold water cannot thoroughly remove accumulated sebum, dust, and makeup residue from the face. Not only does it fail to nourish the skin, but it can also trigger or worsen acne and other skin issues.
Whether to use hot, warm, or cold water for washing varies by individual. Generally, those with non-oily or combination skin should use water above 30°C (86°F) but below body temperature—warm enough to feel comfortably hot to the touch without burning. This temperature easily removes surface dust while opening pores for deeper cleansing.Note that water should not be excessively hot. Temperatures exceeding normal body heat weaken facial blood vessel walls, potentially causing skin to become lax, dry, and prone to wrinkles.
2. Rinse with cold water after cleansing.
When washing, first lather cleanser with warm water, apply to face, and gently massage for 1 minute, focusing on the T-zone.Rinse off all foam thoroughly, then finish with cold water. Cold water boosts blood circulation and enhances skin elasticity. This alternating warm-cold water method not only cleanses the skin but also promotes the dilation and contraction of superficial blood vessels, benefiting facial skin care. 3. Cold water is not suitable for oily skin.
Cold water causes pores to contract, preventing thorough removal of excess sebum, dust, and makeup residue accumulated on the face. This not only fails to achieve beautifying effects but may trigger or worsen acne and other skin issues.
4. Avoid using basins and damp towels.
It's best not to use basins for washing your face. Water in a basin isn't flowing, so dirt from your face and hands can contaminate it. Using this water for cleansing won't effectively cleanse your skin. Therefore, use running water to wash your face. Wash your hands first, then wash your face.
After washing, dry your face with a clean towel. Damp towels can harbor microorganisms, and using one to pat your face negates the cleansing effect.
