Most vitamin C serums either irritate your skin or break down before they can work, leaving you with zero results. This one uses stable vitamin C that actually penetrates to interrupt the process that creates dark spots and uneven skin tone. Sea buckthorn oil provides vitamins A and E that work with vitamin C to fade hyperpigmentation faster, while hyaluronic acid keeps your skin hydrated during the brightening process. Wheat amino acids help repair your skin barrier so everything absorbs better. This doesn't just promise to brighten someday - it actively fades dark spots and evens your skin tone with each use.
