The Ordinary

APLB Glutathione Niacinamide Ampoule Serum (40ml) is a brightening concentrate from the Korean skincare brand APLB, formulated with Glutathione and Niacinamide alongside Centella Asiatica Extract.
Efficacy note: the brand markets this serum as a "potent brightening concentrate" to help fade dark spots, but topical Glutathione's brightening efficacy is scientifically contested -- its large molecular size and instability raise real questions about how well it penetrates skin, and no clinical trial data is cited by the brand. Niacinamide has better-established literature support for brightening and barrier benefits. Treat the brand's specific "fade dark spots" claim as marketing positioning rather than independently substantiated fact.
Apply 2-3 drops after cleansing and toning, spreading across the face and neck, and press gently into the skin, per the official brand instructions.
Store in a cool, dry place away from direct sunlight. Keep the bottle tightly closed after use. Avoid contact with eyes; rinse thoroughly with water if contact occurs. Discontinue use and consult a doctor if irritation develops. Keep out of reach of children.
Q: Which ingredient actually does the brightening work in the APLB Glutathione Niacinamide ampoule serum?
A: Niacinamide, included at a 2% concentration, has the better-established evidence for evening out visible skin tone; the serum's Glutathione content is an antioxidant whose ability to brighten skin when applied topically is still debated among researchers.
Q: Why is Centella Asiatica Extract at such a high concentration in the APLB Glutathione Niacinamide ampoule serum?
A: At 29.2%, it's included mainly to soothe the skin, which can help offset any sensitivity from the active brightening ingredients used alongside it.
Q: Can the APLB Glutathione Niacinamide ampoule serum be used daily?
A: Yes, it's designed to be applied after cleansing and toning as part of a regular routine, though anyone with known niacinamide sensitivity should patch-test before applying it to the full face.
Q: What does Sodium Hyaluronate do in the APLB Glutathione Niacinamide ampoule serum?
A: It's a hydrating ingredient that helps draw moisture into the skin, supporting the serum's overall feel rather than contributing to the brightening effect.
Q: How should the APLB Glutathione Niacinamide ampoule serum be applied?
A: Apply 2 to 3 drops after cleansing and toning, spreading it across the face and neck and pressing it gently into the skin.
Q: Is the APLB Glutathione Niacinamide ampoule serum suitable for broken or highly irritated skin?
A: No, it's not intended for use on broken or highly irritated skin without medical advice.
Q: What should I do if the APLB Glutathione Niacinamide ampoule serum irritates my skin?
A: Discontinue use and consult a doctor if irritation develops.
