If that is all that your doctor said to you, then I would be looking for a new dermatologist. He should have, at least, talked to you about how to best care for your daughter's skin condition.
There is no cure for KP, but there are treatments to help. However, since your daughter is just one year old and has KP on her face, that may eliminate many of these options as baby skin and facial skin are very delicate. There's no way to know until you talk with another dermatologist.
Get a second opinion, and this time, ask for specific things you can do to help manage her condition and keep her skin healthy. Also ask about treatments that may be available to your daughter as she grows.
I would not randomly experiment with any creams or moisturizers until she is seen by another doctor and you are told what you can use, particularly if the first doctor told you that moisturizers would make her condition worse.
