Skin ageing occurs due to both intrinsic (internal to the body) and extrinsic (external to our bodies) biological factors. However, people are often concerned with keeping wrinkles at bay, to slow down the appearance of ageing.
Physical signs of ageing include wrinkles, discoloured skin, pigmented skin. Other skin conditions that affect people’s confidence is skin trauma, bad skin, acne scarring, pitted skin, rosacea. Skin ageing is contributed to by both a combination of what is called endogenous (intrinsic factors). This is why it is extremely important we take care of ourselves, what be put into our bodies, both what we eat and use on our skin. This is because although the effects are not seen immediately by the naked eye, chemicals processes that happen in our bodies can change our genetics, hormones, metabolic processes, and even cellular metabolism.
Extrinsic or environmental factors that can accelerate the process of ageing include: pollution, chemicals, ionizing radiation, chronic light exposure, chemicals, ionizing radiation, chronic light exposure, toxins), which work together to cause both structural and physiological alterations. This makes the skin, especially areas exposed to the sun, to change in appearance.

Obvious signs of ageing are characterised typically by reduced skin elasticity, the development of wrinkles on the skin’s surface, especially wrinkles, discolouration. The epidermis layer of the skin may also become thicker, and seem duller and rough. Skin could also become saggy and lose its previous vigour.
As the human body physically ages, its ability to heal itself; its wounds also decline due to the slowing of the cell cycle and epidermal turnover rate.
A component of maintaining skin elasticity and youthfulness is collagen. Reduced collagen production is most obvious in older skin and people, as the distribution of collagen maybe irregular and disorganised.
An interesting fact of the rate at which collagen levels may decrease per annum: at a rate of 1% per year.
There are 3 primary structural components that make up the skin’s layers:
1) dermis 2) collagen 3) elastin 4) GAGS (Glycosaminoglycans).
Ageing of the face is characterised by loss of the volume of collagen, the impact of gravity (causes sagging), redistribution of superficial and deep fat, loss of bony skeleton support, shape and contour changes – which collectively lead to sagging facial features.
