Tetra Vitamin C 26 is a multivitamin C serum by 30 ml formulated by Norden Mosse with a synergistic combination of four stabilised Vitamin C derivatives that add up to 26% of active ingredients: 12% of 3-O-Ethyl Ascorbic Acid, 5% of Ascorbyl Glucoside, 5% of Ascorbyl Palmitate and 4% of pure Ascorbic Acid. Unlike conventional serums that usually rely on a single derivative, this fourfold approach allows the specific properties of each form of Vitamin C to be harnessed in a complementary way: greater stability, better penetration, powerful antioxidant action and benefits in both aqueous and lipid environments. The formula is completed with Hyaluronic Acid, citrus Polyphenols and Natural Moisturising Factors (NMFs) for a comprehensive action on the skin.
Tetra Vitamin C 26 combines four stabilized derivatives with complementary functions. 3-O-Ethyl Ascorbic Acid (12%) is a highly stable derivative, soluble in both water and oil, with excellent penetration capacity, that brings radiance, evens out skin tone and stimulates collagen production. Ascorbyl Glucoside (5%) is a stable derivative that converts into ascorbic acid within the skin, offering antioxidant and brightening benefits. Ascorbyl Palmitate (5%) is the fat-soluble form of Vitamin C, which penetrates the skin well and provides antioxidant protection while promoting collagen synthesis. Finally, Ascorbic Acid (4%) is the pure and most potent form of Vitamin C, an essential antioxidant that enhances radiance, evens out skin tone and fights ageing.
Tetra Vitamin C 26 is suitable for all skin types and offers multifaceted action. It brings radiance and reveals a glowing complexion, while deeply hydrating thanks to Hyaluronic Acid and NMFs. It protects against oxidative damage, acting as an antioxidant shield against free radicals and environmental stress, also thanks to citrus Polyphenols. It evens out skin tone and reduces the appearance of blemishes, stimulates collagen production to improve firmness and elasticity, and improves skin texture and smoothness, refining its surface for a silkier feel. It's especially suited to skin looking to combat the visible signs of aging and environmental stress.
Apply Tetra Vitamin C 26 morning and/or night to the face, neck and décolletage, always on clean, dry skin, with a gentle massage until fully absorbed. It's important not to overuse the amount applied to avoid saturating the skin or a sticky feeling, and to close the cap properly after each use to prevent product degradation. Store below 26 ºC. Avoid contact with eyes, mucous membranes or open wounds; in case of accidental contact, rinse with plenty of water. A patch test is recommended before use, and if persistent irritation occurs, discontinue use and consult a specialist. For external use only.
Tetra Vitamin C 26 has been formulated with a very carefully considered profile: it is silicone-free, vegan, cruelty-free, organic, encapsulated and fragrance-free. Its base is water-based and it has a pH of 4.2, an optimal value to ensure the stability and effectiveness of the Vitamin C derivatives. Being encapsulated helps protect the actives and enhance their penetration into the skin. As it contains no silicones or fragrance, it's especially suitable for those looking for cleaner, skin-friendly formulations. Together, these characteristics make it a pure and highly effective serum, free from unnecessary ingredients that could compromise its tolerance or ethical standards.
