Nicotinell TTS patches keep working around the clock to help you go smoke free. The patch is designed to you with decreasing amounts of Nicotine as you go from step 1, to 2 and then to 3, helping you to give up smoking all together. Nicotinell patches can help you stop smoking. When you apply the patch, nicotine penetrates through the skin and into the body, replacing the nicotine you would normally get from smoking. The patches come in three sizes. As your body adjusts to not smoking you can gradually reduce the size and dosage of the patch over a period of around 12 weeks until you no longer need to use them
