Skin aging is a chronic physiological process during which cells progressively loose their structural and support function.
Skin gets thinner and tone fade away, wrinkles grow deeper, dark spots or wide areas of pigmentation start showing.
MAIN SKIN AGING CAUSES
Skin aging has clearly a genetic susceptibility influencing chrono-aging progression, but there are many external factors responsible for boosting this process.
Among the extrinsic factors responsible for skin aging, the most involved are certainly UVA, UVB, IR rays and the environmental pollution, since they are constantly and aggressively affecting the skin, inducing short and long term damages.
Sun and Infrared rays cause erythema, itching and burning immediately; on a long run, instead, could be responsible for wrinkles and stains.
Latest scientific studies show that environmental pollution, exhaust gas and particulates, are also involved in speeding skin aging and skin allergies.
The skin is a shield-organ for the body, assigned to the exchanges between inner and outer body space, and deeply exposed to all pollutants.
Skin is under attack any given day and is harmed with:
- photo-oxidation damages ( due to chemical reactions between hydrocarbon of exhaust gas and sun radiations );
- damages due to acidic substances in suspension;
- metabolic damages ( due to heavy metals );
- damages due to lack of oxygen ( by means of carbon monoxide ).
Cells normal functions are altered and overloaded so that dreadful free radicals build up.
