Compare Products: Niacinamide Brightening Toner vs Glass Skin Refining Serum
Ingredient Analysis
Good Molecules Niacinamide Brightening Toner wins for brightening with confirmed percentages of niacinamide, arbutin, and ethyl ascorbic acid. Peach & Lily Glass Skin Refining Serum wins for barrier hydration with four hyaluronic acid forms, beta-glucan, and madecassoside. Choose based on your primary skin goal.
Good Molecules Niacinamide Brightening Toner stacks three confirmed brightening actives: arbutin at 2%, niacinamide at 3%, and ethyl ascorbic acid. Peach & Lily Glass Skin Refining Serum relies on niacinamide alone for tone-evening.
Peach & Lily Glass Skin Refining Serum delivers four distinct hyaluronic acid forms plus beta-glucan and saccharide isomerate, targeting multiple skin depths. Good Molecules Niacinamide Brightening Toner has glycerin and one sodium hyaluronate.
Madecassoside and asiaticoside are well-studied for reducing redness and aiding barrier repair. Good Molecules Niacinamide Brightening Toner's licorice extract is calming but present at only 0.1%.
Good Molecules Niacinamide Brightening Toner discloses percentages for nearly every ingredient. Peach & Lily Glass Skin Refining Serum lists no concentrations, making active strength impossible to verify.
Peach & Lily Glass Skin Refining Serum includes adenosine and a peptide (acetyl octapeptide-3) targeting fine lines. Good Molecules Niacinamide Brightening Toner has no dedicated anti-aging actives.
