I recommend at least these--
An all skin type face moisturizer
an all skin type eye cream
body moisturizer
eye make up remover pads
facial cleansing cloths
Finishing spray--Evian mist, Fix+, UD All Nighter, something like that
Mattifier/pore filler
Primer
Bonus items--
A really rich moisturizer for dry skins
A richer eye cream
A line filler
Pearlescent additive for moisturizers to make them more luminous
Tinted primers
Three shades of BB Cream--Missha has a broader range of the better ones out there and Seoulglamour on Amazon has an amazing price on authentic Missha
