1. Appying a small amount of foundation before adding on any makeup products is highly suggested for an easier blend & hold of everything coming after. 2. Professional cleansing oil/liquid/balm for silicone practice skin could help removing tenacious residue but general makeup remover works just as fine, you don't have to buy 'professional cleansing products" to maintain the "MODEL" 3. Towel or tissue dry after it's cleansed. 4. Keep away from straight and strong sunlights for longer use.
