The term extrinsic comes from the Latin word extrinsĕcus. It’s about a adjective that alludes to that which is external or external already what it is not essential.
For example: “We need to have an extrinsic point of view since we, being involved in the matter, cannot appreciate certain things that are surely observed from the outside”, “Although salary is very important, there are other extrinsic elements that also affect worker satisfaction”, “If you only stick with the extrinsic, you will never get to know the trouble thoroughly and, therefore, you will not be able to solve it “.
The extrinsic is often understood as opposed to the intrinsic. While the extrinsic is external and / or does not constitute the essence of something, the intrinsic is internal and / or is essential.
The extrinsic, therefore, comes from outside or is not your own. It is common to talk about extrinsic aging, to cite one case. This aging, unlike the intrinsic one that is associated with genetics, is caused by variables that are not part of the organism: exposure to sunlight, the smoking habit, etc. Therefore, if a person do not expose yourself to the sun or smoke, you will not suffer these consequences of extrinsic aging.
With regard to intrinsic aging, we can mention the three fundamental factors: the tone, the pigment of the skin provides us with a natural protection against the sun’s rays, which is why dark skin stays better than light skin; the anatomy, Issues such as the composition and thickness of the skin of each part of the body have an impact on not even aging; the hormones, whose changes affect the skin.
Well, extrinsic aging takes care of all other factors, those that come to us in the form of external stimuli and affect even more our inevitable deterioration. Let us return to the case of solar radiation, the main cause: UVA rays cause damage to our skin that leads it to age before its time. Visible light (that emitted by screens) and infrared radiation also enter into this equation.
We have also talked about the consumption of tobacco, which is worse because it not only affects the person who performs it but also their environment. The list of medical studies on the effects of this habit on the skin is endless; The health status of twin brothers has even been compared, in families where only one of them smoked, to show that tobacco is very harmful.
In particular, extrinsic aging caused by tobacco use can be seen through the following signs:
* decrease in flow blood, as a result of which the skin receives less nutrients and oxygen;
* reduction of elastin and collagen, which results in the appearance of wrinkles before time and in greater numbers;
* hyperpigmentation of the skin of the face, which is seen in the form of irregularity in its tone;
* appearance of skin cancer as a result of oxidative damage.
Our feeding It is another factor that affects extrinsic aging, precisely because if we carry it out responsibly, we can adapt it to our nutritional needs. Experts recommend a diet rich in antioxidants, with Vitamin C being one of the most important. The opposite, of course, is one high in carbohydrates and saturated fat.
Take the case of extrinsic factors that affect the condition and quality of a food. Among them are the humidity and the storage temperature, not “Belong” to the product in question, but they can alter its composition and qualities.
