Rescue Serum Deluxe Sample

I love this rich moisturizing serum product for use after the retional and lactic products. This serum glides over the skin with a soothing smoothness. I would highly recommend this product and say it is much needed to accompany the skin thightening products to enhance the skin.

I can not in all fairness give a proper review on this item because I only received a small sample. I would purchase a full sized bottle but where does it fit in? Between the retinol and lactic acid serum do really need the plumping serum?
