Red marks on the eyelids of newborns are often caused by neonatal erythema or neonatal hemangioma. Neonatal erythema is only a temporary phenomenon, with age, most of the neonatal erythema will subside within one month after birth, all other states are good, no special treatment. If the red mark on the eyelid is caused by hemangioma, and the redness is gradually increasing with age, and the color is gradually deepening, it should be treated with laser surgery in time. If the red marks increase in size, there is a possibility that the vision may be affected, and the red marks should be treated very aggressively. Laser treatment is very minimally damaging and can be used with confidence by parents.
