Baking soda water's treatment of skin problems is not only unfounded, but also "burns" the skin. Experts pointed out that the component of baking soda is sodium bicarbonate, and the aqueous solution is weakly alkaline. However, the pH value of our healthy skin is about 5.0 to 5.6, which is slightly acidic. Applying alkaline baking soda solution to the skin will destroy the natural barrier of the skin, which makes the skin more dry and sensitive, and some sensitive skin is easy to sting, swell and even cause infection.
When washing your face with white vinegar, you should also pay attention to dilution. Undiluted white vinegar is too acidic and very irritating to your face. The correct way to wash your face with white vinegar is to put a small basin of water, add a small amount (about two tablespoons) of white vinegar, pour it into the water and mix it well, throw it on your face, or simply immerse your face in warm water and then pour it out.
