Ma:nyo Glutathione 7 Dark Spot Serum (Bundle)
Ingredient analysis and how the ad lines read
Read on 2026-09-07
What is this product?
Ma:nyo's Glutathione 7 Dark Spot Serum earns its name mechanically: exactly seven ingredients (niacinamide, arbutin, glutathione, alpha-arbutin, acetyl glucosamine, kojic acid and ascorbic acid) carry a double-asterisk marker in the verbatim ingredient list, matching the product's own '7 core ingredients' footnote. Two of those seven have disclosed amounts, niacinamide at 50,000ppm and glutathione at 10,000ppm, together already 6 percent of the formula, consistent with press coverage claiming a 12-percent-plus high-concentration blend, though the other five actives carry no individual number.
What makes it different?
A single-arm test (20 women, one Korean institute, two-and-a-half-week window) backs a 21.95 percent surface-pigmentation improvement after seven days of use, with 'individual results vary' attached to every cited figure and no control group disclosed. Tranexamic acid sits sixth in the list but, unlike the seven asterisked actives, is not counted among the brand's own 'core ingredients' marketing group.
