Upon application, TIGHTEYE and TIGHTNECK are heated by your body's natural temperature, triggering the absorption of key anti-aging ingredients by your skin. At the same time, you will feel both products contract on the surface of your skin, providing you with immediate tightness. The combination leaves you with results you can see and feel in 5 minutes. After your treatment gently wipe the serum from your skin with a damp cloth. NOTE: On average it will take 5 minutes for the serum to dry; your treatment is not fully done until the serum has completely dried on your skin. At times this can take more than 5 minutes depending on your body's natural temperature.
