Langues : Anglais (eng) Catégories : Antioxydants Antiradicalaire Astaxanthine Ingrédients cosmétiques Peau -- Soins et hygiène Protection contre le rayonnement ultraviolet Stress oxydatif Index. décimale : 668.5 Parfums et cosmétiques Résumé : The skin is the largest and most exposed human organ and plays a key role in everyone's health and appearance. Every day, the skin is exposed to sunlight and needs support to function as protective shield. The natural carotenoid astaxanthin from the microalga Haematococcus pluvialis is considered the most powerful antioxidant. It neutralises harmful free radicals and is highly effective against the impacts of UV radiation. Astaxanthin cannot replace conventional UV filters, but it can make sun protection products more effective. With its branded active ingredient AstaCos OL50, BDI-BioLife Science has proven these biological protection benefits through human clinical studies. Unlike other antioxidants, astaxanthin does not turn into a pro-oxidant and is therefore called the 'red diamond of radical scavengers'.

Astaxanthin - the diamond of antioxidants in the fight against light-induced oxidative stress / Katharina Dokulil in SOFW JOURNAL, Vol. 147, N° 9 (09/2021)  

[article]  inSOFW JOURNAL > Vol. 147, N° 9 (09/2021) . - p. 2-6 Titre : Astaxanthin - the diamond of antioxidants in the fight against light-induced oxidative stress Type de document : texte imprimé Auteurs : Katharina Dokulil, Auteur ; Alexander Pototschnik, Auteur Année de publication : 2021 Article en page(s) : p. 2-6 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Antiâge Antioxydants Astaxanthine Cosmétiques Dermo-cosmétologie Peau -- Effets de la lumière Peau -- Soins et hygiène Stress oxydatif Index. décimale : 668.5 Parfums et cosmétiques Résumé : The skin, as the largest organ of the body, plays an important role for our health. As a protective shield, it is constantly exposed to external environmental influences and stress. In order to maintain and support this protective barrier, numerous active ingredients are used in cosmetics. A major group of these are antioxidants, which can neutralize stress factors in the skin. Astaxanthin, which is the strongest natural antioxidant belonging to the carotenoid family, does this particularly well due to its special molecular structure. Due to its unique structure of hydrophilic and lipophilic components, it can act more effectively in the lipid bilayers of the skin than most other antioxidants. Especially in the field of light-induced oxidative stress, triggered by UV radiation and infrared as well as blue light, in vitro and in vivo studies with the active ingredient AstaCos® OL50 from BDI-BioLife Science have shown that astaxanthin has a strong protective effect. Numerous research studies conclude that astaxanthin can also improve overall skin health, and provide comprehensive protection against oxidative stress. Possible uses range from anti-aging products to formulations that combat the effects of UV exposure and light, to an active ingredient in sunscreen products and face creams.

Astaxanthin - the red diamond amongst antioxydants / Elisabeth Willeit in SOFW JOURNAL, Vol. 148, N° 10 (10/2022)  

[article]  inSOFW JOURNAL > Vol. 148, N° 10 (10/2022) . - p. 22-27 Titre : Astaxanthin - the red diamond amongst antioxydants : a powerful ingredient to support a radiant and healthy skin Type de document : texte imprimé Auteurs : Elisabeth Willeit, Auteur Année de publication : 2022 Article en page(s) : p. 22-27 Note générale : Bibliogr.

It is not only a barrier shielding of the human body from extrinsic factors. It also functions as a sensory organ, prevents the organism from losing water through evaporation and is the site of immunological defence mechanisms and bio-synthesis (e.g. of vitamin D3). In order to fulfil its various functions, a good skin health is important. An essential indicator of the skin’s health condition is its visible appearance. A firm, youthful-looking skin with a radiant complexion and natural warm glow is not only a desirable feature of beauty, but also indicates a good state of health. However, intrinsic and extrinsic influences like lack of sleep, a poor nutrition, stress, air pollution or solar radiation can cause the skin‘s radiance to fade. Both factors promote an overproduction of reactive oxygen species (ROS) and lead to a state of oxidative stress, a major cause of skin damage and premature skin ageing.

Austrian natural astaxanthin - a unique active ingredient for biological cell protection / Elisabeth Willeit in SOFW JOURNAL, Vol. 149, N° 9 (09/2023)  

[article]  inSOFW JOURNAL > Vol. 149, N° 9 (09/2023) . - p. 14-17 Titre : Austrian natural astaxanthin - a unique active ingredient for biological cell protection Type de document : texte imprimé Auteurs : Elisabeth Willeit, Auteur Année de publication : 2023 Article en page(s) : p. 14-17 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Antiâge Antioxydants Astaxanthine Bien-être Biomolécules actives Cosmétiques Dermo-cosmétologie Peau -- Soins et hygiène Vieillissement cutané Index. décimale : 668.5 Parfums et cosmétiques Résumé : As life expectancy continues to rise, healthy ageing is on everyone’s lips. We strive for eternal youth by maintaining general physical health, wellbeing and the natural functionality of our skin to avoid visible signs of age. A Sisyphean task because we cannot stop the ageing process of our body and skin, but we can positively influence and delay it through preventive strategies. Antioxidants play a very important role to inhibit ageing. The most effective antioxidant is astaxanthin which, due to its biological potential of cell protection, is considered the strongest natural antioxidant. Therefore, it is the perfect choice as anti-ageing ingredient since it acts as a protective shield to reduce environmental stress and skin ageing. Numerous clinical studies have already revealed its positive effects on skin ageing processes due to its unique molecular structure. BDI-BioLife Science can prove the effects of astaxanthin with in-house human clinical studies in the field of cosmetics with its branded active ingredient, an oleoresin with an astaxanthin content of 5 %.

To minimise long-term skin damage associated with pollution, astaxanthin can be used as a second-line protection. Its antiinflammatory activity has been known for a long time and has been confirmed by numerous studies. Especially for cosmetic products, BDI-BioLife Science has developed its own raw material containing 5% of astaxanthin. The properties of the red diamond have been substantiated by in vivo and in vitro proof of efficacy. While its effect against blue light-induced stress has already been proven in preliminary studies, the current research takes a closer look at the issue of blue light.
