Do baby eczema scars fade?

Ne

My poor baby had three different skin conditions going on last week - mild to moderate eczema on his chest and back, the beginning of a yeast infection in his neck and groin, as well as what looks like pityriasis alba on his face and scalp.

I think everything is now under control but he's covered in scars that look like depigmentation.

Do these go away? Will any products help?

He's almost 5 months old if that makes a difference. Also, I had pityriasis alba as a baby and no lasting depigmentation so I'm really more worried about the eczema scars...but any info is appreciated. 😄
