The Ordinary Alpha Arbutin 2% + HA Concentrated Serum 30ml. TO-19025

The Ordinary Alpha Arbutin 2% + HA Serum is a concentrated brightening treatment formulated to reduce hyperpigmentation, dark spots, post-inflammatory marks, and uneven skin tone. Alpha Arbutin is a glucoside derivative of Hydroquinone that inhibits tyrosinase enzyme activity - the key enzyme in melanin production - without the irritation, sensitization, and stability concerns of pure Hydroquinone. Combined with Hyaluronic Acid for simultaneous hydration, it is one of The Ordinary's most consistently recommended brightening formulations.

Specs

• Active ingredients: Alpha Arbutin 2%, Hyaluronic Acid
• Form: Water-based serum
• Volume: 30ml
• Action: Tyrosinase inhibition / brightening / hydration
• Free from: Hydroquinone, parabens, alcohol

Benefits

• Alpha Arbutin inhibits tyrosinase - the enzyme that catalyzes the first and rate-limiting step of melanin synthesis - at the pigmentation source, reducing melanin production in hyperpigmented areas progressively with consistent daily application
• Stable glycosylated form of hydroquinone that does not oxidize or degrade rapidly on skin contact, providing reliable active concentration maintenance throughout the application period unlike ascorbic acid which oxidizes quickly
• The 2% concentration is clinically active for brightening without the threshold of irritation that higher concentrations or pure hydroquinone can cause, making it suitable for sensitive skin types that react to more aggressive depigmenting agents
• Hyaluronic Acid in the formula provides immediate skin surface hydration and maintains the skin plumpness that dehydrated skin lacks, complementing the gradual brightening benefit with an immediate visual improvement in skin texture
• The Ordinary's direct ingredient communication and cost-transparent pricing makes this serum accessible to users who want a clinically relevant brightening active without the premium markup of luxury skincare brands

How to Use

• Apply to the face morning and evening after water-based serums and before heavier creams
• Use 2 to 3 drops and spread across the entire face or focus on dark spots and pigmented areas
• Allow to absorb before applying the next product
• Always apply SPF50 in the morning when using brightening actives - UV exposure counteracts tyrosinase inhibition
• Begin with once-daily evening use if you are new to this product and increase to twice daily after 1 to 2 weeks
• Allow 8 to 12 weeks of consistent use before fully assessing brightening results
• Do not use in the same routine as Vitamin C at high concentrations - use Alpha Arbutin in the morning and Vitamin C in the evening or vice versa
