User Feedback
From r/AsianBeauty:
> “They are marketing it as a 'glutathione' serum, even though it only contains 100 ppm… the heavy‑lifting is by 5% niacinamide” .
“I’ve repurchased this about 3 times… it’s only great for fresh acne… evening skin tone though” .
Summary of user experiences:
Glutathione concentration is low, mainly used for marketing, while niacinamide and tranexamic acid are stronger actives.
Effective at calming inflammation and preventing fresh acne from leaving dark marks, though older pigmentation may not fully fade.
Sensitivity to scent reported—despite being labeled fragrance-free, some detected a mild smell.
