Functions of Skin
Protection
Flexibility and density of the horny layer, collagen in the dermal layer, tensile of the elastic fiber, elasticity and supportive cushion of subcutaneous fats, are able to resist against damages of external impact, friction and even pressure.
Sensory
Our skin, has numerous nerves, receive external stimulation which in turn transmit the sense of touch to the brain through the sensory nerve; resulting in complex feelings such as Dry, Wet, Smooth, Rough, etc.
Regulate Skin Temperature
Tiny blood capillaries will expand when air temperature increases bringing about a rapid increase of blood circulation. On the contrary, when air temperature drops, circulation reduces and slowed. Fluctuation in air temperature causes loss of fluid and fats in the skin which affect the skin's regulating ability. This again, shows the importance to maintain a normal skin temperature.
