I also had the same issue with my newborn but its much better now... i clean with water after every feed and once in the morning & afternoon with mustela cleansing water (red bottle for sensitive skin).
I use Mustela cicastela in the morning and night - it's super helpful and cleared most of my son's acne in about 2 weeks. Now reaching 3rd month soon and completely clear
My baby has baby acne as well and seemed to get worse when she was 3weeks old. I started applying breast milk on her skin and it healed her baby acne in 2 weeks!!
Yup newborn will get baby acne which usually go away when they grow older i didnt really apply anything just constantly clean face with cooled down boil water
My mummy friends recommend the vivaiodays all purpose olive oil, the original one 😊
