Fascinating facts about skin
The skin:
- Is the body’s largest organ
- Makes up about 16% of our total body weight

dead cells, constantly renewing about every 28 days

environment – guarding against bacterial invasion, dehydration and ultra-violet light
(UVL)

withstanding considerable trauma w/out permanent damage

insulation – like a thermostat
