It somehow looks like baby pimples and turned to eczema.. My baby had e same when she was ard 3 weeks old.. It took her a few weeks to slowly recover but once you got eczema it will be a lifetime skin condition.. but this is not any life threatening health issue, just keep baby’s skin clean and moisture as and when needed will do..
If skin flare again, with more than one area of red patches den need to get steroid for baby.. (only Dr can prescribe, which I personally not recommend to my own baby on using too much steroid)..
Try to use Cetaphil cleanser (those that you can always find everywhere) as a replacement as baby’s shower soap/shampoo..
