Dr.BS La Thanh Ha, Head of the Department of Dermatology (Vietnam Academy of Traditional Medicine and Pharmacy), said that it was said that washing the face of salt water brings benefits such as antiseptic, alkaline oil, reducing acne.Some beauty facilities after acne treatment also remind customers to go home to wash their face with physiological saline.
Dr. Ha affirmed that physiological saline can be used to wash their faces, but should not be used regularly.If used regularly, improperly will bring unwanted harmful effects to the skin.
Should I wash your face with physiological saline?
Physiological saline solution is usually sold in the form of bottled in pharmacies, containing 0.9% of NaCl concentration and 1 liter of water.This is the isotonic solution with an approximate osmotic pressure in the human body.The reason why the salt water is often used to clean the wound is due to this isothermal nature, interrupting the normal healing process (advantages compared to pure water).
However, physiological saline is not classified as high bactericidal properties.A 2012 scientific study of the UK informed that the difference in infection rate in acute, surgical or chronic wounds was washed with clean water compared to physiological saline.
"Only salt water is high enough to disinfect, but no salinity should not exceed 9%, will shrink skin cells."The dermatologist said.
Washing your face is an important step in cleansing the skin, using physiological saline to wash your face is difficult to remove excess oil and dirt on the skin after a long day.The consequence of this causes skin clogged skin by excess oil, dirt, sebum, acne, irritating dermatitis.
Not to mention, if you use salt water to wash your face without rinse with water, the salt crystal lingers on the skin, leading to much more sunburnt skin.
