During the summer, the sun causes oxidative stress to your skin. The visible effects are quick to appear: premature aging of your cells, the appearance of wrinkles and fine lines. The minerals, trace elements, and green clay present in this mask provide the necessary benefits to treat the effects of oxidative stress. Rich in minerals (magnesium and calcium), trace elements (zinc, manganese, and phosphorus), and green clay, this mask purifies and heals the skin while leaving it supple and soft. Origin: Guérande, France. Limited offer of only 300 pieces.
