Not brightening in the bleaching sense. Evening out.\u003c\/p\u003e\n\n\u003cp\u003eThe catch with most vitamin C serums is that they strip. This one is paired with hyaluronic acid, so it hydrates while it works, which is the difference between a serum you finish and one that sits in a drawer.\u003c\/p\u003e\n\n\u003ch3\u003eWhat to expect, and when\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeek one to two:\u003c\/strong\u003e skin looks slightly brighter and more awake.

Fresh, it's clear to pale straw. As it ages it turns yellow, then orange, then brown. Pale yellow is fine and still works. Dark orange or brown means it's finished — bin it, because oxidised vitamin C can irritate skin rather than help it.\u003c\/p\u003e\n\n\u003cp\u003eKeep the bottle out of sunlight, cap it tightly, and use it within about three months of opening.\u003c\/p\u003e\n\n\u003ch3\u003eQuestions we get asked\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eIt tingles slightly. Is that bad?\u003c\/strong\u003e A mild tingle for a minute is normal.
