In terms of surface area, the skin is the second largest organ in the human body. For the average adult human, the skin has a surface area of approximately 2 square metres! It weighs in at 10 kg or more, representing around 16 percent of our total body weight. The skin is made up of three layers; the epidermis, dermis, and subcutis. Millions of receptors in the skin serve as the regulation and control centre for our senses. It is our protection from the outside world.
SKIN CELL RENEWAL
SKIN CELL RENEWAL Throughout life, our skin will change constantly, for better or worse. In fact, your skin will regenerate itself approximately every 27 days. Renewal of the outer skin layer is directly tied to our health. It can be stimulated by external factors such as diet and drinking plenty of fluids. Proper skin care is essential to maintaining the health and vitality of this protective organ.
THE TANNING PROCESS OF OUR SKIN
When exposed to sunlight, the skin pigment melanin forms through a multistage chemical process known as melanogenesis in the bottom layer of the epidermis, this is responsible for the unique colour of our skin. Melanin is a protective pigment in our skin, blocking UV radiation from damaging DNA and potentially causing skin cancer. Tanning and melanin production stimulated by the sun exposes our skin to harmful UVA and UVB rays.
TANNING AGENT DIHYDROXYACETONE (DHA)
The essential ingredient of all tanning products is the “Dihydroxyacetone” (DHA) active ingredient. The DHA reacts with the proteins and amino acids in the top layer of the skin – the “horny layer” – thereby producing a visible tan. Advantage: DHA only reaches the uppermost layers of the skin and therefore does not induce side effects such as itching or skin irritation.
