1. mineralized skinfinishes have only been realeased 3 times, i believe, as regular collections. roccoco in 2oo4, goldplay in 2oo5, and lingerie in 2oo5. they were limited edition, and sold out pretty quickly. they're apparently being re-released with a muse/amuse, in late summer. they are not pro, they're just always limited. they're expensive and time consuming to produce, which is why mac doesn't make them permanent.
2. i only use mac wipes. they get everything off, including waterproof makeup and pro longwears, plus, they're super convenient, and smell wonderful. cleanse off oil is an alternative, although i personally can't stand it, some people love it. it does do the job, it just feels super greasy.
