The Goodal Green Tangerine Vita C Dark Spot Care Serum Alpha is named after fruit harvested before it ripens. Green tangerine carries considerably more vitamin C than the ripe orange fruit, which is the reason Jeju's unripe crop ends up in skincare rather than in a fruit bowl, and tangerine extract sits at position two, directly behind water. Niacinamide follows at four. The interesting part is further down: four separate forms of vitamin C — ascorbyl glucoside at thirty-two, plain ascorbic acid at thirty-eight, 3-O-ethyl ascorbic acid at forty-three and sodium ascorbyl phosphate at forty-four. Korean reviewers who read the list pick out that stack alongside the niacinamide and adenosine.
