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.

Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.
Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness.

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!
