Intrinsic, solar and sunbed‐induced skin aging measured in vivo by multiphoton laser tomography and biophysical methods

Background: Skin aging is accelerated by extrinsic factors, particularly actinic damage. Over the last decades, both clinical and pathological differences between intrinsic and actinic aging have been characterized. In this work, we aimed at quantifying skin aging by non‐invasive in vivo methods.
