Sandra Johansson M.D.: As we move through different life phases, our physiology and our whole constitution change. Our skin also changes and adapts, and so do its needs. Skin ageing is caused by a combination of a natural ageing process and exposure to outer influences that prematurely age the skin.
Let us first get to know the skin so we can recognise the coming changes. Did you know the skin has three distinct layers, all performing different functions while working together as the largest organ in our body? It is a living boundary, constantly in flux and has the amazing ability to multitask. It can sense, feel, protect and produce substances our body needs. It protects us against external germs, water loss, temperature change, trauma, UV radiation and more.
The thinnest, outermost layer is called the epidermis – this is the protective layer. Water and fats cover it, making the skin to be supple and pliable. It is inhabited by an ecosystem of beneficial bacteria and fungi that we are only now learning about.
Further inside is a middle layer called the dermis. It has many functions. Cells called fibroblasts produce a network of collagen and elastin fibres, surrounding them with a lubricant of hyaluronic acid, giving the skin its volume, stability and elasticity.
In the lower part of this dermal layer, small blood vessels help regulate body temperature by adjusting blood flow to the skin and deliver well-needed nutrients. At the same time, lymphatic vessels take waste products out. Your body’s natural oils for protecting and moisturising your skin are also made there. All this makes the skin look healthy, glowing, and vibrant.
Our innermost, deepest skin layer is made of fat cells that insulate us and cushion the vulnerable tissues. The process of ageing affects all of these layers. But there is a lot you can choose to do in order to make that process as healthy and beautiful as possible.
