Arbutin VC Brightening Essence
Peterson's Lab Arbutin VC Brightening Lotion (nicknamed "Big C Lotion") is a daily brightening emulsion that targets dullness, uneven tone, and post-acne marks. It combines α-arbutin and stable Vitamin C derivatives to deliver visible radiance while remaining gentle enough for sensitive skin.
