This supercharged Vitamin C treatment includes a powerful antioxidant effect that is developed to provide optimum protection from free radicals, boost skin glow, and target imperfections from photoaging. Use this product if you are looking for visibly brighter, smoother, firmer and younger-looking skin.

In this formula we use three different types of Vitamin C. Why, you might ask? The answer is very simple: because the function of Vitamin C varies within the different layers of the skin, we use the necessary type of Vitamin C when and where it is needed.

There are many types of Vitamin C for skin care applications, and we have selected the most stable and pure to ensure it’s effectiveness within all layers of the skin. Need an explanation? Here you have it:

C-TETRA E.F. has been formulated with 10% Vitamin C Tetra, which is highly biocompatible and liposoluble. The fact that it is liposoluble allows this type of Vitamin C to be transported down into the deepest layers of the skin. Here, its action is focused on melanocytes (to treat blemishes from the inside) and on collagen synthesis (to prevent and fight wrinkles from the inside). The formula is complemented by Ascorbosilane and Ascorbyl Glucoside, two very stable and water-soluble Vitamin C derivatives. They act on the surface of the skin to improve skin glow and reduce the most common blemishes.

The formula is complemented with Vitamin E and Ferulic Acid, the award winning combination that boosts the serum's total antioxidant effect to keep your skin protected, all day long.

KEY INGREDIENTS

20% Vitamin C

Vitamin C Tetra: A fat soluble derivative of Vitamin C. It is super stable and has the ability to penetrate deep into the deepest layers of the skin, without causing irritation. Its main benefits include its ability to stimulate collagen production, its antioxidant protection against free radicals, its ability to visibly improve wrinkles and fine lines, and improve skin tone and brightness to reduce blemishes from the inside-out.

Ascorbosilane: A stable, water-soluble form of Vitamin C derivative. It acts to protect the skin from external aggressions thanks to its antioxidant properties and role in collagen synthesis for firmer, more protected skin.

Ascorbyl Glucoside: A stable and water-soluble derivative of Vitamin C. In addition to the antioxidant benefits of Vitamin C, it visibly improves radiance and skin tone for healthy, younger-looking skin.

1% Vitamin E: An antioxidant, which is naturally present in the skin and acts by neutralizing free radicals. It acts in synergy with vitamin C, enhancing its antioxidant effect to keep skin protected throughout the day.

0.5% Ferulic Acid: Plant-derived antioxidant that helps protect the skin from damage caused by free radicals and sun exposure, preventing premature skin aging. It also acts in synergy with Vitamin C and E, improving the stability and efficacy of the formula.

Super, empfehle ich jedem

Bei empfindlicher Haut empfehle ich es, langsam anzufangen und ggf vorher einen Moisturiser verwenden. Funktioniert super und die Haut strahlt danach. Der Gesichtston ist danach schon ebenmäßig. Ein Muss!

Ebenmäßiger Teint

Benutze das Vitamin C und die Azelainsäure abwechselnd morgens mit anschließendem spf. Finde die Textur meiner Haut hat sich auf jeden Fall verbessert, auch wenn ich noch mit Akne zu kämpfen habe, würde ich nicht mehr ohne das Vitamin C wollen.

Bestes vitamin C serum

Super leichte Textur und tolle Ergebnisse. Mein Dermatologe empfahl sie mir und wies darauf hin, dass man zu Beginn erstmal alle 2-3 Tage morgens auftragen soll, um die Haut zu gewöhnen. Nutze sie jetzt täglich und meine Haut bekommt viele Komplimente :-) habe sie schon 3 mal verschenkt und die Freunde waren ebenfalls begeistert. Tolles Produkt!
