Its formula helps reduce the appearance of existing discoloration while promoting a brighter, more even-looking complexion.<\/p>\n<p dir=\"auto\" data-start=\"5513\" data-end=\"5783\">The serum contains <strong data-start=\"5532\" data-end=\"5563\">20% 3-O-ethyl ascorbic acid<\/strong>, a stable form of vitamin C that helps improve the appearance of hyperpigmentation and provides antioxidant support. This is particularly useful when skin looks dull and needs both a more even tone and renewed radiance.<\/p>\n<p dir=\"auto\" data-start=\"5785\" data-end=\"6088\">Vitamin C is complemented by <strong data-start=\"5814\" data-end=\"5853\">1% tranexamic acid and 0.5% arbutin<\/strong>, which help reduce the appearance of dark spots. <strong data-start=\"5903\" data-end=\"5921\">5% niacinamide<\/strong> supports a more even-looking tone while helping maintain the skin barrier and hydration. Together, these ingredients address several aspects of visible discoloration.<\/p>\n<p dir=\"auto\" data-start=\"6090\" data-end=\"6282\">The patented <strong data-start=\"6103\" data-end=\"6131\">5% Micellar CellRenew-16<\/strong> complex supports moisture retention and helps skin look firmer. This makes the serum relevant when loss of firmness is a concern alongside dark spots.<\/p>\n<p dir=\"auto\" data-start=\"6284\" data-end=\"6550\">The formula is designed to improve the skin\u2019s overall appearance, addressing general dullness and uneven tone as well as individual spots. When used in the morning, its antioxidant action complements daily sun protection, though the serum does not replace sunscreen.<\/p>\n<p dir=\"auto\" data-start=\"6552\" data-end=\"6812\">In a brand study involving 25 participants, after <strong data-start=\"6602\" data-end=\"6614\">12 weeks<\/strong> of use, overall skin tone evenness improved by <strong data-start=\"6662\" data-end=\"6669\">27%<\/strong>, visible brightness by <strong data-start=\"6693\" data-end=\"6700\">29%<\/strong>, and skin clarity by <strong data-start=\"6722\" data-end=\"6729\">31%<\/strong>.
