Sugar-substitute xylitol found to actively slow skin aging

  1. May 18, 2005 #1
    This is a surprise. This is not even topical xylitol; this is orally ingested. (And it tastes good, too. I have tried it.)

    "Collagen fluorescence" is another term for protein glycation (protein crosslinking). Old skin looks old mainly because it is glycated. (This is why facial peels make skin look younger -- glycated skin layers are peeled away and replaced with fresh, unglycated skin. The skin can only be peeled to a certain depth, though, so facial peels cannot completely rejuvinate skin.)
