1. What changes occur to your skin as you get older As you get older, your skin is more easily damaged, the amount of collagen decreases, wrinkles form, age spots form, skin infection is more likely, the ability to regulate body temperature lessens, and your skin gets drier. 2. The rate of water loss from the skin of the hand was measured. Following the measurement, the hand was soaked in alcohol for 15 minutes. After all the alcohol was removed from the hand, the rate of water loss was again measured. Compared with the rate of water loss before soaking the hand of alcohol, what difference, if any, would you expect in the rate of water loss after soaking the hand in alcohol? The alcohol clean the sebum (oil) off the hands. The sebum prevents water loss because oil and water do not mix. When the sebum is removed by the alcohol, the water loss is greater because there is no oil to prevent water loss.
