The Algenist Firming and Lifting Neck Cream was designed to serve as a moisturizing cream that is perfectly suited for the delicate and fragile skin around the neck and decollete area. While you may think the skin on your body is more resilient than the skin on your face, the reverse is actually true for your neck and decollete. In order to address this concern, the Algenist Firming and Lifting Neck Cream utilizes their unique, sustainably produced Alguronic Acid along with a peptide complex to tighten and lift the skin around the neck area. Peptides are amino-acid precursors that help to boost the production of collagen and elastic in the skin. Unfortunately, both collagen and elastin production slows down as we age, so peptides help to substitute for the lost collagen in the skin. Since this formula does not contain more aggressive actives like retinol or AHA’s, we’d recommend this product to those of you who are concerned primarily with skin sensitivity as well as anti-aging.
