Puhdas+ Beauty Collagen Natural only contains collagen and nothing else. Collagen is a protein that makes up 70 % of our skin protein. The production of collagen in the body starts to decrease at the age of 25 and the loss of collagen creates wrinkles and dry skin. Therefore, taking collagen helps you keep your skin young and smooth. Dosing For adults 1 tbsp per day. Mix with a small amount of water, juice, smoothie or yoghurt. The recommended daily dose should not be exceeded. The dietary supplement does not replace a varied and balanced diet or healthy lifestyle. Keep away from the rech of children.
