A complete kit to replenish, nourish and firm skin in just four steps. As skin ages, production of ceramides (lipids, AKA oils, found naturally in skin) depletes, which can lead to loss of elasticity and dryness. This combination of Ceramide Fix heroes replenishes ceramide levels with an active 12% blend that also includes peptides and azelaic acid to refine skin texture and boost elasticity. Coupled with firming, line-plumping retinol, this kit is a 360 routine for a serious youth boost. What's included?
