By combining a lipid-coated droplet technology with an oil-gel matrix and propanediol carrier, the product aims to protect Vitamin C molecules from exposure to air and moisture. The airless pump packaging further reduces oxidation, so the serum stays fresh from the first pump to the last drop. Additional skin-supporting actives—adenosine, panthenol, and beta-glucan—are included to help maintain barrier health and hydration alongside brightening benefits.\u003c\/p\u003e\n\n\u003ch3\u003eHow does SUMSAE keep vitamin C stable without water?\u003c\/h3\u003e\n\u003cp\u003eThe serum’s waterless format eliminates a key factor in Vitamin C degradation.
