Alpha Arbutin 02% is a popular facial serum sold by the Minimalist brand. The company claims it's effective for "dramatically reducing dark spots" and supporting "brighter, even-looking skin."
But does Alpha Arbutin serum contain research-backed ingredients for improving skin quality? Does it contain any unhealthy ingredients? And is this product better or worse than other popular budget serums like Good Molecules Discoloration Correcting Serum?
In this article we'll answer all of these questions and more, as we analyze the ingredients in Minimalist Alpha Arbutin 02% to give our take on whether or not it's likely to improve facial skin quality, and whether or not it's healthy.
We'll also compare the brand to other popular budget facial serums to pick our winners (and losers) from a formulation quality perspective.
Key takeaways:
- Contains research-backed depigmenting active ingredients
- Contains three inactive ingredients we consider unhealthy
- We do not currently recommend Minimalist Alpha Arbutin Serum

Alpha arbutin is the ingredient from which this product gets its name, is described in a clinical review as a "skin depigmenting agent."
The researchers also note that it may cause dermatitis or allergic dermatitis.
Lactic acid was shown to increase skin firmness and smoothness in a clinical trial published in the Journal of the American Academy of Dermatology.
Ferulic acid is clinically shown to improve skin barrier function, as we documented in our Drunk Elephant Bronzing Drops review article.
Pullulan is used to increase the absorption and site-specific availability of other active ingredients, according to a 2023 medical review.
There are three inactive ingredients in this formulation that we consider unhealthy when used in combination.
Triethanolamine is a pH balancer which was shown to be irritating and potentially harmful to the eyes in a clinical trial published in the Occupational & Environmental Medicine journal.
Phenoxyethanol is a synthetic preservative shown to be toxic to human cells in a clinical trial published in the Experimental Eye Research journal.
Ethylhexylglycerin is a synthetic preservative shown to potentiate the toxic effects of phenoxyethanol in a 2016 medical review.
We consider Minimalist Alpha Arbutin face serum likely to be effective for depigmenting, but we don't currently recommend this product due to the inactive ingredients highlighted above.
Minimalist Alpha Arbutin vs. Popular Budget Cosmetics
Here's how Minimalist Alpha Arbutin facial serum compares to other budget-friendly cosmetic brands in regard to potential efficacy and healthiness, in our opinion:
Global Beauty Care
This dollar store brand's skin cream contains shea butter, which is clinically shown to support skin barrier repair and to have anti-inflammatory effects.
While the formulation we analyzed contained one inactive ingredient we consider unhealthy, that's two less than in Minimalist's serum.
Global Beauty Care has the advantage from a health perspective.
Winner: Global Beauty Care
Good Molecules
Good Molecules Discoloration Correcting Serum is one of the most popular budget, anti-aging skincare picks.
As we documented in the above-linked review, the serum has research-backed anti-pigmentation ingredients, has the concentration of every ingredient published, and is free of any unhealthy additives.
We consider Good Molecules to be the winner from both a potential efficacy and a health standpoint.
Winner: Good Molecules
Bubble Moisturizer
Contains more active ingredients we could find research backing to support potential efficacy for than Minimalist.
Contains fewer inactive ingredients we consider unhealthy.
Winner: Bubble Moisturizer
