How does light therapy relate to the anatomy of the skin?

The skin is designed to not allow absorption of substances but light therapies can easily penetrate the skin without causing trauma or discomfort.

Each light works on a different frequency and penetrates to a different depth within the skin. As can be seen from the image LED treatments have the ability to penetrate further into the skin than most aesthetic therapies and there is the added benefit of it causing no pain, discomfort or necessary downtime.
