Tears secretion will increase when crying or in pain, and when tears soak the skin for a longer period of time, the pH value and composition of tears will have certain irritation to the surrounding skin, especially the mucous membrane, so some people are more sensitive and may cause red spots on the surrounding skin. When you stop crying, the redness will usually be eliminated automatically after a few hours. If the redness lasts longer, it can be eliminated quickly by applying hot compresses or local lubricating and anti-allergic ointments such as Vaseline, or by applying hormone-containing eye ointments such as D&B eye ointment for a short period of time.
