A friend of mine who has just given birth got perplexed when she saw tiny pimples on her son's face. I remember that my son had that too when he was a newborn. They're actually called Milia. According to my little research, they are known as milk spots or oil seeds that disappear in a few weeks so there's no need to look for and peruse acne product reviews. This is caused by a certain type of yeast causing a primary skin infection. They also clear up in a few weeks time although sometimes, it could linger for months.
