MedEasy found significant inconsistency in the ingredient information available for this specific serum, and we want to be transparent about this rather than present a single list as certain. Two independent retailers list different ingredient sets for this product, and neither closely resembles a standard, brand-verified INCI panel. We also checked FDA DailyMed's cosmetic facility registration records for the manufacturer, but the relevant filings there are for a related product -- the "Melao Whitening Cream," not this serum -- and those cream filings even conflict with each other on the Alpha Arbutin concentration (one states 2%, another states a figure roughly a thousand times lower). Given all of this, we treat "2% Alpha Arbutin" as the brand's own labeled/marketing claim for this serum rather than an independently confirmed concentration, and we were not able to confirm a complete, reliable ingredient list for this exact SKU. We recommend checking the product packaging directly for its definitive ingredient list.
Melao is a Chinese cosmetics brand; the manufacturer associated with Melao-branded products in FDA facility registration records is Guangzhou Yilong Cosmetics Co., Ltd., based in Guangzhou, China. This serum is typically marketed alongside two other headline actives -- Kojic Acid and Licorice Root Extract -- in addition to Alpha Arbutin, positioning it as a multi-active skin-brightening serum rather than an Alpha-Arbutin-only formula, based on how retailers commonly describe the fuller product name.
Alpha Arbutin is generally considered a gentler skin-brightening alternative to hydroquinone, and is associated in the skincare literature with helping reduce the appearance of dark spots and uneven tone with regular use. Kojic Acid is also a commonly used brightening ingredient, though it can be a sensitizer with prolonged use in some individuals. However, because we could not confirm a reliable, complete ingredient list or verify the actual concentrations used in this specific serum, we are not able to make confident, product-specific claims about its effectiveness, and recommend treating brightening claims with appropriate caution until you have reviewed your own product's packaging.
Brightening serums of this type are generally marketed to those seeking to address dark spots or uneven skin tone. Standard dermatological guidance for Alpha Arbutin and Kojic Acid-containing products generally advises against combining them with other strong actives (such as high-percentage AHA/BHA exfoliants or low-pH Vitamin C) in the same routine without spacing them apart, and recommends daily sunscreen use, since brightening actives are most effective and safest alongside sun protection. Individuals with known sensitivities to Kojic Acid or Licorice-derived ingredients should exercise caution and consider a patch test before regular use.
Serums of this type are typically applied to clean skin, in small amounts, avoiding the eye area, usually followed by a moisturizer. Because MedEasy could not confirm the manufacturer's specific usage instructions for this exact product, we strongly recommend following the instructions printed on the product packaging, which take precedence over this general guidance, and introducing the product gradually to monitor skin tolerance.
Store in a cool, dry place away from direct sunlight. Keep out of reach of children. Avoid contact with the eyes; if contact occurs, rinse thoroughly with water. Discontinue use if irritation, redness, or an allergic reaction develops, and consult a doctor if symptoms persist. Because we could not confirm a complete, reliable ingredient list for this exact SKU, we are not able to provide a definitive allergen disclosure; individuals with known sensitivities to brightening actives such as Kojic Acid should review their specific product's packaging closely and consult a dermatologist if uncertain. Daily sunscreen use is strongly recommended while using brightening serums of this type.

Q: Can the Melao Whitening Alpha Arbutin serum be used with Vitamin C or exfoliating acids in the same routine?
