NIOD Elasticity Catalyst Neck Serum is a non invasive anti-ageing formula that utilises a host of intelligent technologies to help increase & protect visible skin elasticity. Contributing to the increase & strengthening of elastin on slackened skin, the serum targets neck lines & sagging to help improve elasticity & density, both on & below the skin's surface. Key Technologies: Pro-Elastin & Pro-Elastic-Fibre Technologies: These technologies help increase & strengthen elastin. They support cellular cohesion, strengthen elastic fibre & restore elastin protein synthesis for a visible increase in skin viscoelastic properties. Anti-Elastase & 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 & Subcutaneous Density Technologies: These technologies work to increase visible skin density on & below the surface. Caffeine, Carnitine & Bitter Ginger create a 'push-pull' effect to keep skin 'active'. This counter-intuitive approach enhances visible tone by increasing & decreasing fluid motion simultaneously; this 'push-pull' action improves skin density & surface evenness because the fluids are distributed more evenly.
