NIOD Elasticity Catalyst Neck Serum is a non invasive anti-ageing formula that utilises a host of intelligent technologies to help increase and protect visible skin elasticity. Contributing to the increase and strengthening of elastin on slackened skin, the serum targets neck lines and sagging to help improve elasticity and density, both on and below the skin's surface.;Pro-Elastin and Pro-Elastic-Fibre Technologies: These technologies help increase and strengthen elastin. They support cellular cohesion, strengthen elastic fibre and restore elastin protein synthesis for a visible increase in skin viscoelastic properties.;Anti-Elastase and Anti-Progerin Technologies: Elastase is an enzyme that breaks down elastin; these technologies inhibit the performance of elastase to help counteract sagginess that occurs when elastin breaks down.;Dermal and Subcutaneous Density Technologies: These technologies work to increase visible skin density on and below the surface. Caffeine, Carnitine and Bitter Ginger create a 'push-pull' effect to keep skin 'active'.
