Ingredient analysis and how the ad lines read

What is this product?
Begins by Jung Saem Mool's Trace-Fading Serum is a Korea-registered functional cosmetic (the specific function is not itemized in the sourced record) built for post-blemish marks: alpha-arbutin, niacinamide and a disclosed 100ppm each of glutathione and guava fruit extract, plus madecassoside and asiaticoside for soothing. All the brightening logic checks out on ingredient science, but the two most talked-about actives here, alpha-arbutin and niacinamide, carry no disclosed amount, so there is no way to judge strength from the label alone. It ships as a limited bundle whose retail label block records the volumes: a 30ml serum, a 30ml refill and a 5ml cream miniature.
What makes it different?
Glutathione and guava fruit extract are both pinned to a precise 100ppm, an unusually specific disclosure for a brightening serum in this category, while every other named active is undisclosed. Clary sage, orange peel and patchouli oils sit near the end of the list, carrying limonene as a declared, naturally occurring constituent rather than an added fragrance compound; no separate parfum entry appears.
