- RonaCare® Tiliroside, a natural solution for dry and sensitive skin
If your customers suffer from skin that’s blotchy, dry, sensitive, or tends to get irritated easily – they’re not alone. In fact, the frequency of “problem skin” has increased dramatically over the past few decades. And while heredity is partly to blame, our increasingly harsh environment plays a serious role in compromising skin health. At Merck, we’ve developed a solution that could bring even the most sensitive skin back into balance: RonaCare® Tiliroside And we knew who could help us best: Mother Nature. Introducing RonaCare® Tiliroside, a natural and healthy way to keep skin smooth and free of discomfort.
RonaCare® Tiliroside, a natural solution
RonaCare® Tiliroside is a bioflavonoid – meaning it’s part of an enormous group of plant metabolites whose valuable properties have been known through the ages. In nature, tiliroside is found in the tender young leaves of certain plant species – shielding from intense UV-irradiation and minimizing stress to the delicate plant tissue. Merck has isolated the natural protective principle and developed it into a powerful ingredient for skin products: RonaCare® Tiliroside
How does RonaCare® Tiliroside works
The skin’s aging process is accelerated by external or internal stress factors that trigger repeated micro-inflammation processes. Inflammation parameters can be detected not only in obvious inflammations but also in people with very sensitive and reactive skin, possibly disposed to dermatitis, allergies or psoriasis. Fortunately, RonaCare® Tiliroside keeps those molecules in check, reliably defending skin well-being and thus working against accelerated skin aging.
Tried and true
Extensive testing has shown RonaCare® Tiliroside to be effective against multiple threats to the healthy and youthful appearance of skin:
- An in vivo study confirmed that a formulation containing just 2% RonaCare® Tiliroside clearly reduces both visible redness and capillary flow caused by UV radiation
- Further testing has shown that Tiliroside can lower the levels of other harmful substances – like TNF-alpha and Interleukin-12 – connected with inflammation
- Its ability to inhibit histamine release makes Tiliroside a powerful cosmetic ingredient for highly reactive skin types.
With RonaCare® Tiliroside, you can inhibit skin-damaging free radicals, fight the enzymes that threaten the integrity of your skin and prevent it from overreactions – all at once.
