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 which 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) it creates tiny holes in the film.
