To understand the value of nanotech skincare products, it is important to understand how the skin works. The outermost layer of the skin, called the stratum corneum, acts as a protective barrier. Its job is to keep harmful substances out and it is very good at it. Unfortunately, this also means that most skincare ingredients have a hard time getting through. What you apply on the surface often stays there.
Many products may sit on the skin, giving a temporary glow or softness, but they never reach the layers where collagen is produced or where pigmentation begins. That is why even the best formulations can lead to slow or minimal results if the delivery method is not effective.
