Alpha-Arbutin,Sodium-Hyaluronate
Ingredients Details
Alpha-arbutin
Common Name(s): 4-hydroxyphenyl-alpha-d-glucopyranoside
DESCRIPTION
What It Does: Provides potent tyrosinase inhibition with improved stability and tolerability over other arbutin forms.
Why It's Used: Premium arbutin โ alpha configuration provides 10ร greater tyrosinase inhibition than beta-arbutin at equivalent concentration, making alpha-arbutin the most effective arbutin form.
How It Works: Alpha-glucoside linkage provides enhanced metabolic stability vs beta-arbutin (less enzymatic hydrolysis to free hydroquinone in skin). inhibits tyrosinase via competitive substrate inhibition (ic50 ~24ฮผg/ml vs beta-arbutin ~525ฮผg/ml โ 20ร more potent). inhibits dopa oxidase step in melanogenesis.
Typically Found In: Brightening serums,anti-spot products,premium lightening

SCIENTIFIC NOTE
Alpha-arbutin's 10โ20ร greater potency vs beta-arbutin at equivalent concentration arises from the alpha-glycosidic bond geometry โ the alpha configuration positions the hydroquinone aglycone at a specific orientation relative to the glucose that fits the tyrosinase active site copper more precisely than the beta isomer's different spatial arrangement.

SCIENTIFIC NOTE
Phenoxyethanol's widespread adoption as the primary cosmetic preservative followed the phaseout of parabens from many formulations in the 2000s-2010s. despite having a comparable or better safety profile to parabens, it is often cited in 'free-from' formulations โ a consumer perception issue rather than a scientific safety concern.
