You use the warm water to wash the face and body. Do not use the cleanser.
Add some Oilatum into the warm bath water and soak inside for 10-15 mins.
After bathing, you must apply the cream e.g. oil or physiogel:AI Cream or Intensive Cream. And you always apply the cream again.
If it becomes more serious, you can consider my doctor. But the doctor fee is quite expensive. If you need, you can pm me.
My baby had this before. Only pat pat, hand and feet's skin is beautiful. Face, chin, neck, chest, back, elbow and leg also become red, especially the face. I have a post before. At that moment, I am not brave enough to take the photo and post her because I feel very very sad and tired.
