The décolletage area is the first to show the signs of premature photo-ageing, caused by UV-light DNA damage on this particularly fragile skin. Combined with our patented ArganCellActivÒ Youth Re-Activating formula, the world’s first proven to stimulate dermal stem cells, the Décolletage Regenerating Silk includes the exclusive StressCellRepairTM, which helps (1) repair UV-induced DNA damage and (2) protect from excessive environmental and oxidative stress. Its key endonuclease DNA-repair technology was just awarded the 2015 Nobel Prize of Chemistry.
