Key Ingredients
Stabilized Glutathione, Alpha Arbutin, Kojic Acid
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.

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.
