Penetrate & protect your skin with the L' Occitane Immortelle Precious Youth Serum, 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 & maintain skin's firmness. The lightweight formula also acts on the 3 main important stages of collagen: production, protection & 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 & weakened collagen fibres are rebuilt to fill in wrinkles. Apply both morning & evening directly onto clean skin, & follow with your preferred moisturiser.
