Natural cosmetics and our skin
A strong team
The skin is a mirror to our soul. It reveals how we live, how we feel and how we care for ourselves. And it is constantly changing, as it is influenced by a number of factors.
RESEARCH AND DEVELOPMENT
The central pillar of the BIRKENSTOCK NATURAL SKIN CARE active ingredient concept is a multi-active cork oak complex.
REDUCED SECRETION OF THE INFLAMMATORY SUBSTANCE TNF-α
This study was performed with human epithelial cells (ARPE-19). After adding an inflammatory agent, the cells were treated with 1%, 2%, or 3% multi-active cork oak extract. The result shows a dose-dependent reduction of TNF-α (-44% at 1%, -68% at 3%).
2. INCREASE OF COLLAGEN CONTENT
REDUCTION OF SKIN REDNESS
A clinical study of 20 subjects aged 30 to 50 years with sensitive skin and mild rosacea showed: Using a cream containing 0.5% cork oak extract over a period of 28 days twice daily reduces the amount of hemoglobin – and redness – by 59% compared to a placebo cream. At the same time, the collagen content can increase, which significantly improves the structure of the connective tissue.
3. PREVENTION AND REDUCTION OF SKIN REDNESS
MULTI-ACTIVE CORK OAK EXTRACT
Helps the skin respond better to inflammation that can be caused by UV rays. After only three applications, skin redness is reduced by as much as 70%.
