Why We Love It

✨ STABILIZED VITAMIN C WITH UNIQUE TRANSPORT MATRIX - Our organic vitamin C serum was not developed as an aggressive mono preparation, but as a care serum based on organic aloe vera.

Our serum guarantees this through sensible dosage with an innovative transport matrix and natural active ingredients specially tailored to vitamin C.
🍀 ROUNDED UP WITH NATURAL INGREDIENTS - In order to further increase the effectiveness of vitamin C and stimulate cell renewal, we rely on well-tolerated and effective ingredients such as organic grape leaf extract, provitamin B5 and vitamin E. DERMATEST has also confirmed the exceptionally good tolerability and advanced formulation with its most recent test result – VERY GOOD.
🌸 HYALURONIC ACID GIVES YOU THE BEAUTY KICK - Beautiful skin is not only free of redness and pigment spots, but fresh and youthful. Our formula therefore also contains hyaluronic acid, the gold standard in modern skin care. We use various hyaluronic acids in the optimal chain lengths to guarantee the maximum effectiveness of our anti-aging formula. Our formula is therefore highly effective and very well tolerated
🌷 NATURAL & SUSTAINABLE ORGANIC COSMETICS BASED ON ORGANIC ALOE VERA - Your body is a miracle of nature. We therefore believe that nature offers a solution for every skin problem. We therefore only use natural and natural ingredients of the highest quality. You will never find dubious ingredients such as parabens, microplastics and silicones in our products.
❤️ ORGANIC - VEGAN - MADE IN GERMANY - Manufacturing in Germany allows us to meet our high quality standards. This means we are always on site and can carry out ongoing checks to guarantee our high production standards. We also support small and regional production facilities in Germany.
