In Skincerity, the acetone serves four purposes:

  • Prepares and cleans the skin
  • Keeps the masque in liquid form so it can easily be
    rolled on
  • Keeps bacteria from growing in the bottle (the
    roller ball makes contact with both skin and bottle
    contents)
  • Is a catalyst that creates micro-porous holes that allow
    oxygen to reach the skin, which is vital for healthy
    skin. The acetone evaporates so fast (it is on the skin
    for only 2–4 seconds) that it creates tiny holes in the
    film.
