I HAVE A QUESTION: In the long run, which do you think is healthier for you....Nature's sunscreen or your dermatologist's sunscreen?
This study pretreated mice with 630nm red light, 30 min twice a day for 5 days and then hit them with UVB light.
Compared to the UVB only group, the red light group kept denser, better organized collagen and elastin, higher Claudin-1 (a tight junction protein that holds skin barrier together) and lower oxidative stress markers.
Red light was a preconditioning signal. Their skin handled the same UV dose better because the repair machinery was already turned on.
Red light is the sunscreen Nature formulated for you.
Morning sun does this for free while UV is still low and red and infrared are higher in proportion.
Cant get morning sun? Then do the hack. A good red light therapy machine with 630nml is the lab version of Nature's sunscreen.
"We found that pre-treating with (red) LED improved skin morphological and histopathological conditions compared to those only exposed to UVB irradiation....LED therapy may modulate key skin barrier proteins and oxidative stress markers. These results demonstrate that pretreatment with LED light can enhance the skin’s resistance to UVB-induced damage by modulating gene regulation associated with skin protection."
"This study underscores the potential of LED therapy as a non-invasive approach to enhance skin repair and counteract the effects of photoaging caused by UV exposure."
