How your skin ages?
It's easy to forget the skin is an organ - just like our heart or liver - which performs a list of life-sustaining tasks. It regulates body temperature. It is the body's sensor, registering pressure, temperature and pain. It is a barrier against the elements and a shield against bacteria and viruses.
Skin is also the body's first line of defence. As such, it is easily damaged both by external causes - sunlight, air pollution - and internal factors, such as cigarette smoke or a diet that lacks nutrients, particularly antioxidant nutrients such as vitamin C and E. It is the way we treat our skin - not the ageing process - that 'ages' facial skin the most.
Scientists explain it this way: there are two types of ageing, 'extrinsic' and 'intrinsic'. Extrinsic (external) ageing is intrinsic ageing aggravated by external causes like sunlight, air pollution, and inflammation caused by harsh detergents, rough treatment, cosmetics and illness.
Intrinsic (internal) ageing is the rate of ageing that occurs with the passage of time. It is a pre-programmed process that is imprinted on our cellular DNA. There is no changing it.
With age, our body's ability to repair itself slows considerably. When we're 11, our cells can repair themselves nearly perfectly from damage, but at 50, the ageing process begins to accelerate because we no longer have that ability.
Meanwhile, inside our skin cells, free radicals activate molecules that go straight to the cell's DNA. Here, they turn on something called AP-1. This begins producing collagen-digesting enzymes that can leave tiny defects in the skin. Known as 'microscarring', this is the birth of a wrinkle.
As you get older the production of growth hormone and oestrogen levels decrease resulting in the slowing down of skin cell renewal and a thinning of the skin, loss of elasticity, deeper wrinkles and a duller complexion.
The ARK skincare range aims to works to balance out these effects by using plant isoflavones, known as phytohormones, that are said to have oestrogen-like effects. Added to that, amino acids in ingredients and supplements support collagen and hormone synthesis, improving skin cell activity and repair.
