Your skin is your body’s largest organ. The top layer – or epidermis – is your interface with the outside world. Its appearance reflects the life you have led, your general health and the skincare routines you practise.

But there is much more to your skin than its top layer. The visible signs of ageing, including dryness, fine lines and wrinkles, are actually symptoms of what’s happening below the surface in the lower layer known as the dermis. It is here that you find your skin’s building blocks - collagen, elastin fibres and moisture-retaining elements and here that the first signs of ageing begin.
