The organic flower extract and ecsin (active molecule in the fruit) from the horse chestnut tree are known to affect the micronutrient network. A product of Clarins Laboratories expertise, this invigorating duo maximises the penetration of nutrients in the skin. Your skin is better nourished and its radiance is restored. Nutri-Lumire Day Emulsion is lightweight and non-greasy, the ideal emulsion-in-oil for revitalising, nourishing and restoring radiance to undernourished skin. Suitable for all skin types.
