Have no fear, the age-fighter is here. This super-powered serum does it all —brightens, fights aging and protects. The key to its multi-tasking power lies in a potent complex of antioxidant vitamin C, lactic and malic acids, which work at the molecular level to give skin a firmer, brighter look. L-tyrosine, an essential amino acid, joins forces with vitamin B5 to soften the look of fine lines. Your skin is worth fighting for.
