I have been using the blackcurrant powder daily for about a year now and apart from it being a delicious addition to my smoothies, muesli, yogurt etc., I have noticed significant improvement in many aspects of my health. Hyperkeratosis on my legs has completely healed without any other treatment and overall condition of my skin has improved visibly. My job involves frequent handwashung and I used to suffer from sore, cracked skin on my hands, especially over winter months. These days I hardly ever use handcream as the skin on my hands is healthy and smooth. My whole family uses the powder now as part of our diet to boost immune system too. This reduces severity of any infections to minimum. I wouldn't go without this product and love supporting Viberi with my purchase.
