Tears on the face generally do not damage the skin, but if tears are frequent or for allergies, the skin on the face may be damaged to varying degrees.
Most of the components of tears are water, and the remaining components are inorganic salts, proteins, lysozyme, etc. If you shed tears only once in a while, and dry your eyes in time afterward, it usually won’t cause damage to the skin on your face.
It should be noted that if you often shed tears and do not wipe them away in time afterward, you may experience dry, itchy facial skin after being stimulated by the wind. If the patient is prone to allergies, when the tears flow to the face, contact rash may occur, mainly manifested as redness and swelling, accompanied by varying degrees of itching.
Therefore, try to avoid frequent tears in ordinary life.
