Infantile acne – More than 30% of newborns develop acne on the face which appear as small red bumps. Infantile acne usually begins around three to six weeks of age and may last 6-8 weeks. The cause is believed to be the transfer of maternal hormones just prior to birth. Since it is temporary, no treatment is necessary and it will resolve on its own. Baby oil or ointments may make it worse.
Drooling rash – Frequently babies will have a rash on the chin or cheeks that comes and goes. This is especially true in the dry winter months. Often these rashes are the result of contact with food or acid that has been spit up. Treatment is simply wiping the face with a soft moist cloth after feedings or spitting up.
Heat rash - This may appear on the face. These appear more in areas that come in contact while being held against the mother’s skin while nursing; these are seen more in the summer months. Changing baby’s position more frequently and applying a cool moist washcloth on the area usually helps.
Milia – This common newborn rash affects 40% of newborn babies. It is seen on the face, most commonly on the nose and cheeks but the chin and forehead may also be affected. Milia look like pimples but are much smaller and are not infected. They are actually blocked skin pores and the rash usually resolves by age four to eight weeks. No ointments or creams should be applied as this will clog the pores even more.
Mongolian spots – These bluish-green or bluish-gray birthmarks are flat and appear in over 90% of Native American, Hispanic, Asian and black babies. They are also seen in 10% of white children, especially those with Mediterranean descent. They are usually seen over the back and buttocks but can occur anywhere on the body. They are not associated with any disease and may vary in shape and size. Most fade away by 2-3 years of age, although a small few may persist into adulthood.
Stork bites or pink birthmarks – Flat pink birthmarks, also called capillary hemangiomas, occur in over 50% of newborns and are usually seen on the eyelids, the bridge of the nose and the back of the neck. The vast majority of these birthmarks appearing on the eyelids clear completely by 1 year of age, while those on the bridge of the nose may take a few years longer. Those that occur on the forehead and run from the bridge of the nose up to the hairline commonly persist into adulthood.
