Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Arbutin is a naturally occurring molecule (found in bearberry, cranberry, and blueberry) that is used in skincare as a gentle brightening agent to fade dark spots, melasma, and post-inflammatory hyperpigmentation.
Chemically, it is a sugar-bound form of hydroquinone.
It works mainly by inhibiting tyrosinase, the enzyme your skin uses to make melanin. This means less new pigment gets produced over time.
There are two forms you'll see on labels: beta-arbutin (listed as just "Arbutin") and alpha-arbutin (the more stable and effective of the two).
The evidence behind this is solid: it's less cytotoxic to melanocytes than hydroquinone and comparably effective with kojic acid for hyperpigmentation.
One human study using a 10% solution reduced UVR-induced hyperpigmentation by 43.5% (jumping to 63.3% when paired with aloesin).
More recent clinical work backs it up too; a 2025 study on a 5% alpha-arbutin + 2% kojic acid cream found it comparable to triple combination prescription formulas but with lower recurrence for melasma.
Typical usage in cosmetics serums land in the 1-2% range.
It's a well-tolerated, non-irritating, and non-photoreactive ingredient that also gives some antioxidant benefits too.

That's why you'll see Kojic Acid in products that target dark spots, hyperpigmentation, and general uneven skin tone. It also pairs well with other brightening actives like Alpha Arbutin, Glycolic Acid, and Vitamin C derivatives.
By latching onto the copper that the enzyme tyrosinase needs to function, Kojic Acid prevents less pigment from being made. It's so well-established that researchers regularly use it as the go-to benchmark when testing new brightening ingredients.
Some other perks include documented antioxidant and antimicrobial properties. The The CIR (Cosmetic Ingredient Review) Expert Panel concluded Kojic Acid is safe for use in cosmetic products at concentrations up to 1% and the EU's SCCS (Scientific Committee on Consumer Safety) considers it safe as a skin lightening agent at concentrations up to 0.7%.
One thing to know about Kojic Acid is that stability is its weak spot; it is sensitive to light, heat, and air exposure and will oxidize/turn brown in formulations. Its derivative, Kojic Dipalmitate, was developed as a stable alternative.
Some individuals have reported contact sensitization so be sure to patch test if you have reactive or sensitive skin.
Fun fact: It was first discovered in 1907 and naturally occurs in the production of sake, soy sauce, and miso.

So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Remember to stay hydrated!
