Remedies for baby acne

Hi all. How to deal with baby acne? My NB is 23 days old and it is heartbreaking to see her face breakout with baby acne. I tried applying BM but on second thought, will bm actually make things worse because milk contains some sort of “food residue” that is sweet in nature? pardon my ignorance as I am a FTM😅 I know some people recommended using calendula oil too. But Google says best not to put any lotion and the acne will usually go away by itself? not sure what is the best way…It has been almost 5 days and still doesn’t look better, I really hope they will heal faster.
