Rashes

Hi. So, my lo has these rashes on her face sguro a month na. Di namin masyado pinapansin kasi mawawala sila bigla tas babalik ulit. Akala namin dahil lang sa panahon and kapag naiinitan sya. Kaso, this time, medyo matagal na rin, di parin nawawala and medyo nagwoworry na kami. We tried calamine lotion as prescribed by her tita, she's a doctor by the way, pero di sila nawawala ng todo. And then we are now trying calmoseptine ointment, may go signal naman ng tita nya and this is her first day using it since marami dn nagrerecommend dun. Just wanted to ask, how long bago natanggal rashes ng baby nyo using the ointment? Any other recommendations that you can share?
