Each nano chip needle is less than 80nm in size is only 1/1000 of a human hair. When the nano chip gently touches the skin it creates thousands of invisible nano channels that can deliver nutrition to deeper into the skin, safely and effectively, raising the absorption of your skincare products as much as 20x. Using the dermapen at home is safe and painless.
