Skin is the largest human organ, covering the entire body and holding around 20% of your body’s water.  It’s full of lipids and proteins to keep your skin healthy and moisturised and skin has vital health protection functions such as protecting us from infection and helping to regulate our temperature so look after your skin, it does more than you think!

It’s something we often take for granted but our skin has four health protection functions, all of which help us stay healthy and even protects us from danger.


Your skin is your first line of defence from the outside world and acts as a protective layer for our bodies. It is an effective ‘natural filter’ against infection and harmful unwanted bacteria

Temperature regulation

Your skin is vital in keeping the body at its optimum temperature of 37°C and protecting it from the extremes of heat and cold. When you are hot, blood vessels dilate below the skin and the body perspires to lower your temperature. Conversely when cold, blood vessels under the skin constrict to reduce blood flow to maintain your core temperature by reducing heat loss.

Defence mechanism

The skin works with your immune system and can recognise infectious agents to trigger the body’s natural defences.

Touch and feel

Skin is covered in millions of highly sensitive nerve endings that enable you to sense heat, warmth and cold and so you can sense and feel what’s on and against your skin. Those nerve endings send messages to your brain to protect the body from danger and so you can literally feel your way around the world.

How can Dettol help keep your skin healthy?

Hand and personal hygiene play a critical role in preventing the spread of illness and infection. Poor personal hygiene can cause infection, skin complaints, unpleasant smells and bacterial or other skin infections.

Skin is our first line of defence from the outside world and by keeping skin clean and moisturised, the barrier function will stay intact and overall health and appearance of skin will be improved. To strengthen this first line of defense you can use an antibacterial body wash to keep your skin clean.

Every day your hands come into contact with potentially harmful bugs and bacteria, from using the toilet, to just touching surfaces around you. As a result, hand hygiene is particularly important, as contaminated hands and failure to practice good hand hygiene are primary contributors to the spread of infectious diseases.
