Kefir as cosmetic active ingredient: CefiraProtect™ for radiant and resilient skin
Kefir has been known for centuries for its health-promoting properties and is celebrated as a ‘superfood’ in social media. Now, kefir a cosmetic active ingredient has also found its way. Kefir as an active cosmetic ingredient strengthens the skin barrier, reduces oxidative stress and promotes a healthy skin microbiome. With CefiraProtect™, the company CLR has developed a vegan, postbiotic formulation that makes the active ingredient kefir usable for skin care and is based on the concept of skin resilience.
What is kefir and how is it made?
Kefir is a fermented milk drink that originated in the Caucasus. Nomads fermented milk with the help of ‘kefir grains’ – small probiotic cultures that can transform milk into a healthy probiotic drink. These nodules, also called ‘probiotic jewels’, are used to make kefir and consist of a symbiotic community of bacteria and yeasts that produce valuable nutrients and antioxidants.
The main active ingredient of kefir, kefiran, has numerous health-promoting properties, including anti-inflammatory, antioxidant and immune-boosting effects. Due to its positive effect on the skin, kefir is becoming increasingly important as an active cosmetic ingredient.
