Signs that a nevus of bright red is healing on its own are a gradual lightening of color and a gradual reduction in its size. Generally speaking, the vast majority of nevus erythematosus does not heal on its own, and only a very small percentage does.
Nevus erythematosus is a malformation of the microvessels, which usually appears when the newborn is born, or about one month after birth. It is a bright red or dark red patch that often occurs on the face, neck, and occipital area, and the majority of nevus erythematosus does not fade with time.
The regression of nevus erythematosus is different from other types of hemangiomas, such as strawberry hemangiomas, which can slowly fade over time in infants and toddlers after the age of 1 year. In the case of nevus erythematosus, only a very small number of children will slowly regress over time, with the color gradually becoming lighter and the extent gradually becoming smaller and receding.
If you have a bright red nevus, you need to go to the hospital as soon as possible, and not wait for it to subside on its own, so as not to delay the treatment time.
