How long does it take for red marks on a newborn's face to fade?
The time it takes for facial red marks on newborns to fade varies depending on the nature and cause of the marks. If the mark is neonatal erythema, it typically fades within 7-10 days; if the facial red mark is a birthmark, it may not fade. Parents should closely monitor the newborn's condition and seek medical attention promptly if any abnormalities occur. Detailed explanations are as follows:

Neonatal erythema is a common physiological phenomenon, usually caused by the newborn's delicate skin reacting during the adaptation to the external environment. This type of erythema typically appears around the 2nd or 3rd day after birth and does not require special treatment, fading naturally over time. In most newborns, the erythema will gradually fade and disappear within 7-10 days.
Birthmarks are caused by abnormal proliferation of skin tissue during development, and it is relatively common for newborns to have birthmarks. Red marks caused by birthmarks generally do not fade spontaneously. However, most birthmarks do not affect health, only aesthetics, and whether treatment is needed can be decided based on specific circumstances. If a birthmark affects the development of organs, it is recommended to seek timely medical attention and actively undergo treatment.
During the period when the red marks on the newborn's face have not faded, it is important to keep the skin clean, gently wipe the newborn's face with warm water, avoid applying excessive force to prevent skin irritation, and use a soft towel or gauze. Avoid rough materials to prevent skin damage.
