Quick Verdict
Best for: post-acne marks and sun spots, at an unbeatable price point. Skip it if: you want the fastest possible fading — alpha arbutin is gentler and slower than stronger tyrosinase-inhibitor combos.
What Is This Serum?
Alpha arbutin is one of the most well-studied skin-brightening ingredients, working by inhibiting the enzyme (tyrosinase) responsible for producing excess melanin. The Ordinary’s version pairs it with hyaluronic acid for hydration, in their usual no-frills, low-price format.
Key Ingredients
- Alpha Arbutin 2% — inhibits melanin production at the source
- Hyaluronic Acid — adds hydration to offset any dryness

Frequently Asked Questions
How long before you’d notice fading?
Since cell turnover takes 4-6+ weeks even in younger skin, most people need 8-12 weeks of consistent daily use before seeing meaningful fading of dark spots.
Can you use it with vitamin C?
Yes, they work through different mechanisms and are commonly layered — vitamin C in the morning, alpha arbutin at night, or vice versa depending on your routine.
