Alpha Arbutin at 2% has a well-established safety record. No synthetic fragrance, no parabens, no SLES, no formaldehyde releasers, no AHAs, no synthetic alcohols, no dyes — one of the cleaner irritation profiles in this product range. 4-Butylresorcinol, appearing later in the list, is a potent tyrosinase inhibitor permitted in both the EU and India at cosmetic use concentrations. Some laboratory studies have noted cytotoxicity at high concentrations, but the trace amount present here is well within the safe range. Dimethyl Isosorbide appears near the top of the ingredient list, indicating it is a dominant component: it acts as a penetration enhancer, driving actives deeper into the skin and amplifying their effectiveness. This also slightly increases systemic absorption of everything in the formula — worth knowing when stacking multiple actives.

Using two tyrosinase inhibitors simultaneously — Alpha Arbutin (2%, confirmed) and 4-Butylresorcinol — is more effective than either alone, because they work through complementary mechanisms to block melanin production. Dimethyl Isosorbide appears very high in the list, acting as the dominant delivery vehicle and maximising how effectively these actives reach the melanocytes where they need to act. Ferulic Acid helps stabilise Alpha Arbutin in the formula. Two forms of hyaluronic acid (standard molecular weight and hydrolysed lower molecular weight) address hydration at different skin depths. The concentrations of Ferulic Acid and 4-Butylresorcinol are not disclosed by the brand.

The full ingredient list is on beminimalist.co and Alpha Arbutin at 2% is brand-confirmed. The brand acknowledges 4-Butylresorcinol on the product page, which is a commendable transparency step — most brands do not call out supporting actives by name. The concentrations of Ferulic Acid and 4-Butylresorcinol are not disclosed, which is typical industry practice for secondary actives. No unsubstantiated marketing claims are made. No third-party clinical data has been published for this formula.

PETA-certified cruelty-free. Vegan. No synthetic fragrance, no dyes, no silicones. Uses biodegradable chelating agents rather than EDTA.
