Skin Ageing; Biological and Photoaging
There are two main causes of skin ageing, biological (as you age in years) and photoaging (caused by exposure to sunlight).
They are different and the effects to the skin also vary. You could have two individuals of the same biological age in years, however the effects of photoaging can impact hugely on the condition of their skin depending on their history of sun exposure and sun-protection measures.
Skin Biological Ageing Characteristics
Biological ageing is characterised by an overall thinning of the skin, loss of plumpness and deep expression lines. There is a loss of elasticity however it will be unblemished. Combining factors to biological skin ageing include genetics, environmental and hormonal changes. The biological ageing process takes place with all our body organs (remember our skin is the biggest organ of them all) but it shows visibly in our skin.
Skin Photoaging Characteristics
Photoaging is characterised by a change in skin texture giving a leathery appearance, deep set wrinkles and skin furrows and there is also the presence in some cases of benign, premalignant and malignant growths. The skin will also show irregular pigmented discolouration patches. Excessive sun exposure causes thickening of the skin and changes the function of your melanocytes (cells which produce melanin, the pigment released to help protect the DNA in our cells from UV damage) causing sun spots.
Facial Skin Ageing
The facial skin ageing process is complex and is progressive as we age. In this blog post I want to highlight that there is a difference between the effects of ageing as we grow older and the advancement and different issues that can complicate this through sun exposure.
Branded moisturisers and other products that are sold on the promise of bringing back the flawless, youthful glow can only do so much, certainly I will always advocate a high SPF moisturiser. To make real corrective action and ‘Reverse’ the signs of ageing you need to make changes at the cellular level rebuilding the structure of the skin and reset cell function to make a proper impact on the appearance of the skin.
