2- Absorption & elimination: As the largest digestive organ of the body, the skin provides the functions of both absorption and elimination. This method can work for or against us, depending on the products we employ to the skin. Just like consuming "junk food," junk skin care products could produce negative effects. Conversely, eating a healthy organic diet and using healthy, organic skin care products as "skin food" will increase the health, beauty, and vibrancy of our skin.
3- Sensation: Our skin tells us how things feel whenever we touch them. For example, our skin could tell us whenever we are touching something dangerous (something really hot or sharp). One square inch of skin contains millions of cells as well as numerous specialized nerve endings for sensing heat, cold, and pain.
4- Regulation: Your skin also serves as a heat regulator; sweating when you are hot allows the water to evaporate and cool the skin. when your body is chilled, the vessels become narrowed and diminish the flow of blood through the skin to retard heat loss.
5- Production: Your skin makes Vitamin D in response to sun exposure. Vitamin D is an acute factor of the way your body handles the needed nutrients calcium and phosphorus in your diet. As a result, it is critical to the development and maintenance of bone strength. The amount of vitamin D produced from sun exposure varies based on skin type, use of skin protection, length of sun exposure, season of the year, and time of day.Dermology
