Eyeshadow Base is functioning as the primer/base before applying eyeshadow. It can enhances color, prevent from melting/smearing, and covers unwanted tone on the crease. Truthfully, because I have dry skin on the entire body, I don't need an eyebase. Moreover, the texture of Canmake Eyeshadow Base is creamy. I had thought it would smear, especially if I use a cream eyeshadow such as Laneige Two Tone Shadow Bar. But considering this one is a must have item, I often saw it on Youtube, I need to make it a try.
On picture, the SB is the darkest shade in front of PP (Pink Pearl). In Indonesia, we just have the SB one right now.
