You must use Skin Illustrator Activator, Skin Illustrator Slow Activator, or 99% alcohol to activate the color pigment. Do Not use 70% alcohol, MEK, acetone, water or any other solvent.
Removal is easy with PPI's Telesis Super Solv or Telesis Makeup Remover.
NB. Due to the high pigment content and lack of unnecessary fillers in the Skin Illustrator color system, cracks, bubbles and any shrunken appearance that may occur in some dried color cells does not affect the quality or performance of the product in any way.
