What is Revitalift Derm Intensives Vitamin C Serum? A dermatologist validated, powerful anti-aging Vitamin C serum formulated with 10% Pure Vitamin C that visibly boosts skin’s radiance 1 week and visibly reduces wrinkles in 2 weeks. What Does Vitamin C Do? Our highest concentration of Vitamin C neutralizes free radicals that lead to skin aging, which visibly reduces wrinkles and leaves skin looking brighter and feeling softer. 10% Pure Vitamin C has been formulated for the optimal vitamin C skin absorption and efficacy, at an optimal pH. This formula has also been developed and tested to be safe for sensitive skin. Unique Packaging:Vitamin C formulations are highly unstable and therefore they can become ineffective over a short period of time. Water, oxygen and UV will inactivate Vitamin C formulas; therefore, unique packaging and formulation measures need to be taken. This serum is uniquely stabilized with: -Anhydrous Formula (without water), - Stabilized in a metal tube for zero UV exposure, - 5% Nitrogen Blanket Technology that shields the formula from direct contact with outside lining of metal, - Cap ensures minimal oxygen exposure to formula during usage (oxygen is unable to enter the tube) What Else You Need to Know:Revitalift Derm Intensives products were validated in partnership with an advisory panel of dermatologists who certified:- Screening of ingredients to uphold our formulation standards - Independent Clinical Testing Protocols and Results APPLICATION: Every morning and evening, smooth a pea size onto face, avoiding the eye area.
