I think the steam treatment has been helping my vessels repair itself alot more. My crusts still form & as a matter of fact they are harder to come off. Like i said the crust are necessary in my case so the vessels can be repaired. But your probably in the stage where the bodies trying to make water proof skin, so you might not get as much crusts.
My lips are severely damaged so i dont know how long it will take for my vessels to rebuild the lips, but i know that the steam treatment is helping because i cant see the pigment starting to change colors.
