It helps the skin to return to a fresher, brighter and more even appearance, with daily antioxidant care.<\/p>\n<p><strong>Antioxidant trio:<\/strong> 15% vitamin C + 0.5% ferulic acid + 1% vitamin E form a targeted combination for skin that lacks freshness, radiance and uniformity.<\/p>\n<p>The formula combines two stable forms of vitamin C: 3-O-Ethyl Ascorbic Acid and Tetrahexyldecyl Ascorbate, along with 0.5% Ferulic Acid and 1% Vitamin E. This combination provides powerful antioxidant support and is aimed at radiance and a more even complexion. The result is a more rested appearance of the skin, brightened hyperpigmentation and protection against oxidative stress.<\/p>\n<p>With the double complex, we get 15% of vitamin C from two complementary forms. One is primarily hydrophilic and the other is lipophilic, thus the formula combines the different properties of vitamin C in one serum. The formula also contains hyaluronic acid and nourishing vegetable oils.<\/p>\n<p>If you want a serum that combines radiance, a more even complexion and powerful antioxidant care, this is the step in your routine.<\/p>\n<p><strong>Safe for pregnant and lactating women. Does not increase skin&#8217;s sensitivity to the sun.<\/strong><\/p>\n<p>&nbsp;<\/p>\n<p><strong>Key ingredients:<\/strong><\/p>\n<p>3-O-Ethyl Ascorbic Acid: a stable vitamin C derivative that combines strong antioxidant activity and evens skin tone.<br \/>\nTetrahexyldecyl Ascorbate \u2013 THD Vitamin C: a stable, oil-soluble derivative of vitamin C. Unlike water-soluble forms of vitamin C, its lipophilic structure allows it to fit well into the lipid part of the skin.<br \/>\nFerulic acid: a potent plant-based antioxidant that works particularly well in combination with vitamins C and E.<br \/>\nVitamin E: an antioxidant that helps protect skin lipids from oxidative stress.<\/p>\n<p><strong>Why two forms of Vitamin C?<\/strong><\/p>\n<p>Our formula uses a combination of 3-O-Ethyl Ascorbic Acid and Tetrahexyldecyl Ascorbate (THD Vitamin C). 3-O-Ethyl Ascorbic Acid is a stable, water-soluble derivative of Vitamin C. It was selected for its excellent stability and contributes to a more radiant and even-looking complexion.<\/p>\n<p>Tetrahexyldecyl Ascorbate is an oil-soluble Vitamin C derivative. Its lipophilic nature allows it to blend seamlessly into the lipid phase of the formula, while its action targets antioxidant care, radiance, and the appearance of uneven skin tone.<\/p>\n<p>By combining water-soluble and oil-soluble Vitamin C derivatives, we aimed to create a more comprehensive and elegant formula that provides daily antioxidant care without the need for pure ascorbic acid.<\/p>\n<p><strong>Why ferulic acid?<\/strong><\/p>\n<p>Ferulic acid is a well-known antioxidant ingredient often paired with Vitamins C and E. In this formula, it is used at a concentration of 0.5% to further enhance the serum&#8217;s antioxidant profile. Its role is to support a formula designed to protect the skin from oxidative stress and help maintain a fresher, more radiant complexion.<\/p>\n<p><strong>Why Vitamin E?<\/strong><\/p>\n<p>Vitamin E (Tocopherol) is included in the formula at a concentration of 1%. As a lipophilic antioxidant, it complements the oil-soluble form of Vitamin C and ferulic acid particularly well.<\/p>\n<p>Beyond its antioxidant role, Vitamin E contributes to the formula&#8217;s nourishing properties, helping to keep the skin soft and well-cared-for.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>How to use:<\/strong><\/p>\n<p>Gently massage onto cleansed skin of the face and neck.
