The secret of natural youth lies in this serum of excellence. The Pur’Immortelle BIO Serum offers an exceptional concentration of Organic Immortelle and Hyaluronic Acid (3%). Thanks to a synergy of two types of Hyaluronic Acid, one moisturizing and the other anti-aging, the Pur’Immortelle Serum retains the water naturally present in the epidermis, contributes to the formation of Collagen, and slows down skin sagging. It is an exceptional anti-aging treatment with a soft and fluid texture. Its bottle, equipped with a glass pipette, allows for targeted and delicate application on the most concerned areas of the face (eye contours, forehead, nasolabial folds…). Composed of more than 99.5% ingredients of natural origin and certified organic.
