Skin Explained: Ageing Skin

Skin ages just as the rest of the body does but while there are some elements of the skin ageing process that can’t be prevented, there are ways to slow appearance of the visible signs of ageing with care and attention. 

Skin Explained: Ageing Skin

What happens to skin when it ages?                                                           

To understand how skin ages, it’s important to understand how skin is configured. The skin is made up of three layers - the epidermis, dermis, and subcutaneous tissue - which all age in different ways. The epidermis is the skin’s outermost layer and provides a protective barrier. This layer is rich in keratin that provides toughness and water-resistance. It is where melanin (the dark pigment responsible for giving skin colour) is produced and where dead cells are shed. The dermis, or thicker middle layer, contains collagen and elastin, which provide strength, firmness and elasticity. It also contains blood vessels, immune cells, nerves and glands that produce sweat and oil. Finally, the subcutaneous layer is composed of connective tissue and fat, which keep the body warm and holds the internal organs in place.                                                           

As the body gets older our skin doesn’t retain as much moisture and epidermal cells don’t slough off as quickly. The collagen and elastin in the middle layer break down and as a result skin is less firm and

elastic. Gravity is constantly pulling the body down and as skin becomes less elastic - much like an old rubber band - it is less able to resist this force and starts to sag instead of bouncing back. Thus fine lines form around the eyes, on the forehead and around the corners of the mouth. The jaw and neck slacken and become looser.


What causes ageing?

These ageing processes happen due to both intrinsic and extrinsic factors.


Intrinsic ageing is the natural ageing process that takes place within the body regardless of outside influences, as the years pass. At around 20, collagen production starts to fall resulting in skin becoming thinner and more fragile as the years pass. The skin’s exfoliation process decreases in the twenties too, causing dead skin cells to accumulate and stick together for longer periods of time.

In the thirties and forties collagen and elastin fibers gradually break, thicken, stiffen, clump together, and lose their elasticity making the skin appear duller and less plump.

Finally, in our fifties, the skin becomes dry because the sebaceous (oil) glands produce less oil. In women, menopause causes a decrease in oestrogen levels, leaving the skin drier, thinner and less toned.


The second cause of the appearance of the signs of ageing is known as extrinsic ageing and occurs as a result of environmental factors such as sun exposure, pollution and smoking. But unlike intrinsic ageing, it can be controlled to an extent because it is a result of external factors. Extrinsic ageing shows up as thickening of the cornified layer, freckle and sun pigmentation. Extrinsic ageing can also be responsible for excessive loss of collagen, elastin, and glycosaminoglycans (GAG's). These processes give the skin the appearance of roughness, uneven tone, brown patches, thin skin and deep wrinkles.


How to care for ageing skin

A good skin care regime can make a huge difference to how it ages. Protection from the sun and pollution are key first steps to battle extrinsic ageing. Broad-spectrum sun protection against both UVA and UVB rays is crucial all year round, using an SPF. Regular cleansing morning and evening will help to shift the effects of pollution and encourage the skin to shed dead skin cells.
