Pomegranate extract rich in ellagic acid, an ally for your skin!

Ellagic acid is a polyphenol found in certain fruits and vegetables, mainly berries, pomegranate and some oilseeds. It is known for its antioxidant properties: it helps eliminate toxins and protects against free radicals. Basically, plants produce this compound as a defense mechanism against infections and parasites.

Ellagic acid is a good photo-protector for the skin: it limits the production of pro-inflammatory cytokines and free radicals (oxidative stress), as well as the degradation of collagen due to UV-B rays, which reduces the formation of wrinkles, epidermal thickening and pigmentation, making the skin more luminous. 1,2,3,4 Some studies on mice even suggest that it could be a good treatment for inflammatory skin diseases (dermatitis, edema), or wound healing.5,6

Ellagic acid could be a good anti-carcinogen because it inhibits tumor cell proliferation in animals. It also modulates inflammation and may block viral infections. 7 It also regulates lipid metabolism and the intestinal microbiota, and alleviates the complications of type 2 diabetes.8

You can find pomegranate extract in the following Swiss Alp Health products: ExtraCellWoman and BeautyCollagenMatrix.
