Marigold extract. New research shows that Morgenfrus Extract protects human skin against photo-aging by reducing oxidative damage. Marigold extract stimulates collagen production down in the basal cell layer and in this way prevents thin skin. Marigold Extract is also used for its calming properties. To make an anti-aging hand cream for all skin types, I use Marigold Ecxtract to make the hand cream ideal for both normal and sensitive skin types.
