SKIN UNDER THE MICROSCOPE

The skin is the body’s largest organ. Its most obvious job is to keep internal organs safe and healthy. The skin has three basic layers: the upper: defensive epidermal layer, the middle: collagen-filled dermis, and the bottom: cushioning subcutaneous layer.

Let’s start with the lowest layer, the deepest layer of the skin where you can find subcutaneous tissue, the hypodermis, or the subcutis. It is not technically part of the skin, but it helps attach the skin to the bones and muscles. The hypodermis contains mostly fat and is responsible for elastin which is an elastic protein that helps tissue return to its normal shape after stretching.

The second layer is the dermis. Here strings of collagen and elastin reside, surrounded by a matrix of molecules. It also gives the skin strength and elasticity. If the dermis stretches a lot, such as during pregnancy, then it can tear, and this will show up later as stretch marks. Apart from this, its main roles are to produce sweat and oil, to provide sensation and blood to the skin, and finally, to grow hair. 

Then we have the epidermis - the upper layer of the skin. It is a waterproof barrier that gives skin its tone. Its main roles are to make new skin cells, to give the skin its colour and to protect the body from the external environment. The epidermis is also divided into 5 different layers, and each has its own unique characteristics and functions. The lower layer of the epidermis is called the basal cell layer which constantly makes new cells. After around four weeks, these cells make their way to the surface, become hard, and replace the shedding, dead cells. The basal cell layer is also known for producing cells called melanocytes. Melanocytes are responsible for the skin colouring or pigment known as melanin which gives skin its tan or brown colour and helps protect the deeper layers of the skin from the harmful effects of the sun.

The stratum corneum is the top layer of the epidermis and is made up entirely of dead skin cells in brick-like layers. Between the skin cells there is a sea of lipids (oil-soluble molecules) acting as mortar. The lipids are made up of ceramides, cholesterols, and fatty acids. This structure provides an impermeable barrier against the environment, protecting the skin from pathogens and blocking the loss of water molecules. The pH of the skin is around 4.5-5.5; slightly acidic due to a layer of sebum which hinders alkaline-loving pathogens.

Our bodies begin to lose collagen at about age 30. The effect becomes noticeable. 

The skin becomes less firm and elastic as the cell renewal process slows down. The skin becomes thinner which leads to less protection against the environment and sun. The sweat glands in the hypodermis layer also start to produce less oil as we get older which might seem like a relief to all those oily skin sufferers, but it can result in dryness and itchiness as it’s difficult to keep the skin moist. Having an anti-aging skincare routine is important if you want to look 30 when you are 40! But it’s not just about trying to turn back the clock. It’s also about having healthy, glowing skin no matter your concern. Taking preventative measures at an early age in your 20s and establishing a solid skincare routine should be at the forefront.
