The Ordinary Alpha Arbutin 2% + HA is a lightweight brightening serum that targets dark spots and uneven skin tone using a high 2% concentration of purified alpha arbutin supported by hyaluronic acid. This water-based, fast-absorbing formula visibly fades hyperpigmentation, age spots and post-acne marks while keeping skin hydrated, making it a popular choice for a more even, radiant complexion.

Why This Serum Works

Alpha arbutin works by inhibiting tyrosinase, the enzyme that drives melanin production, which helps reduce the appearance of dark spots and discolouration over time. The Ordinary uses it at 2%, double the standard 1% concentration found in many brightening serums, in a pH-optimised base that keeps the active stable and effective in solution. Because alpha arbutin targets only areas of excess pigment, it fades marks without altering your natural skin tone. Hyaluronic acid supports delivery and adds a layer of lightweight hydration, so the serum brightens and replenishes moisture without leaving skin feeling dry, tight or greasy.

Ideal For

This brightening serum is suited to anyone wanting to reduce dark spots, post-acne marks, sun spots and general uneven tone, and it works for all skin types thanks to its gentle, lightweight texture. It can be layered with other treatments such as niacinamide for added brightening or retinol in an evening routine, making it easy to slot into an existing regimen. Results are gradual and typically become visible after around eight to twelve weeks of consistent daily use, so patience and regular sunscreen are key to seeing and protecting your progress. Patch test before first use, and if irritation occurs, reduce frequency or stop use and consult a professional.
