Reviewed ingredient relationships
Labels summarize the scope of the reviewed evidence. Formula-supported does not mean every separately formulated product pair is synergistic, compatible, or suitable for every person.
A four-week randomized study in 44 healthy participants evaluated finished serums containing 2% or 3% tranexamic acid together with 2% niacinamide, 4% alpha-arbutin, and 4% galactomyces ferment filtrate. Pigmentation measures improved, but the multi-ingredient design cannot isolate this pair, prove synergy, or establish results for separately layered products.
The pair appears in directly relevant finished-formula or regimen evidence. This does not prove that every product pairing is synergistic.
