Follow with the panthenol cream, which delivers a cooling effect to close pores and seal in a moisture barrier. To minimize oxidation of light- and oxygen-sensitive vitamin C, the ampoule is packaged in four separate 2.1 g bottles, each sized for approximately 3 drops per use.\u003c\/p\u003e\u003ch3\u003eClinical brightening results after 4 weeks of use\u003c\/h3\u003e\u003cp\u003eA human application test confirmed the following improvements.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eUp to 38.5% reduction in deep hyperpigmentation area (after 1 week)\u003c\/li\u003e\n\u003cli\u003eUp to 35.3% reduction in surface hyperpigmentation area (after 1 week)\u003c\/li\u003e\n\u003cli\u003eUp to 12.3% improvement in under-eye pigmentation (after 1 week)\u003c\/li\u003e\n\u003cli\u003eUp to 9.9% improvement in overall skin tone (after 4 weeks)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eDermatologist-tested.
