They show up just as fast, but these are more like a pimple in appearance. However, there is nothing to pop and get rid
of. Instead, there is a semi-hard bump under
the surface [fairly far under the surface] which is white (maybe with a faint yellow tint). It appears, at first, if you can squeeze it and pop it, but in most cases, you cannot. In some cases, I am able to scratch my finger nail over it and get rid of it.
