ABSTRACT
The use of noninvasive methods for clinical studies is indispensable for research in healthy skin physiology. It is even more invaluable when the subject of investigation is infant skin.1 Thankfully, a panoply of physical methods have been developed with the aim to extract useful information about skin noninvasively. It can be argued that of these methods, the ones that are based on tissue optics (spectroscopy, macro-and microimaging) are the richest in information content.
