What does it mean that 107 genes were tested and 45 were activated?

In the landmark 2025 study published in the Aesthetic Surgery Journal, researchers conducted comprehensive genetic testing. Of the 107 genes analysed, many of which are associated with processes related to ageing, collagen production, inflammation and cellular stress, 45 showed significant modulation. The study provides scientific evidence of how photobiomodulation technology interacts with cellular signalling at a genetic level.
