L'Occitane Immortelle Precious Youth Serum 30ml is a facial serum designed to penetrate and protect your skin, with a targeted formula that helps to prevent every aspect of anti-aging. The anti-aging power stems from patented innovative concentrates, created from more than 1000 Immortelle flowers in every jar. These potent concentrates help to correct wrinkles and maintain skin's firmness, the lightweight formula also acts on the three main important stages of collagen: production, protection and repairing. Immediately, the epidermis is restructured for smoother skin, resulting in lifted skin. Over time, the skin feels firmer due to stimulation in collagen production and weakened collagen fibres are rebuilt to fill in wrinkles.
