There was a time when skin care was about using only a few topical products. Today, when cosmetology uses innovative scientific developments, the line between the inner and outer sides of health begins to disappear: effective care goes hand in hand with formulas that work at the cellular level. First step? Combating oxidative stress is a major factor in the destruction of skin cells. The essence of the process and the most effective preventive measures were sorted out together with the doctor, dermatologist of the Polyclinique health and beauty center, Inna Vladimirovna Masaleva.
What is oxidative stress?
In the conditions of modern technogenic civilization, when the imbalance between nature and man has reached its peak, stress seems to many of us a normal state, although in reality it is not at all so. Its accumulation leads to the development of pathological changes in various organs and systems of the body.
The negative influence of environmental factors also adds fuel to the fire. Among them are: tobacco smoke, air pollution by emissions from transport and industrial enterprises, ultraviolet radiation, high-energy (blue) radiation, xenobiotics, excessive use of drugs, pesticides, etc., excessive emotional stress.
What is their real danger to the health and beauty of the skin? All of the above factors increase the rate of formation of free radicals in the human body. Free radicals - reactive oxygen species - are highly reactive, due to which they easily damage biological membranes of cells.
What does this lead to? The appearance of chronic diseases, which in particular include acne, rosacea, psoriasis, etc., as well as premature aging of the body.
Normally, the formation of free radicals occurs continuously - this is a natural biological process. Free forms of oxygen are involved in a variety of vital processes - the synthesis of biologically active substances, the exchange of collagen, provide a bactericidal effect, regulate the permeability of cell membranes.
But if an excessive amount of free radicals accumulates in the body, cells inevitably become damaged. At this point, the skin is exposed to powerful oxidative stress: it is based on the so-called lipid peroxidation - the main process in the main theories of aging. As a result of oxidative stress, the risk of developing various pathological conditions, autoimmune diseases and premature aging processes increases (see also: “The rate of aging: how to recognize and slow it down at the cellular level”).
How can you protect your skin from oxidative stress?
If you notice that your skin has become dull, less elastic and prone to regular breakouts, it's time to start pumping the body's antioxidant system - your main weapon in the fight against free radicals.
Antioxidants are molecules that can stabilize their activity and, in emergency situations, destroy them. In addition, they promote active regenerative processes in the dermis and play a primary role in maintaining youthfulness and beauty of the skin (see also: "Antioxidants in cosmetics:" soap bubble "or the secret of eternal youth?").
Vitamin E is one of the most important antioxidant membrane protectors: it effectively protects cells from the toxic effects of ozone. Vitamin A also protects cell membranes, improving the quality of the skin.
Vitamin C is not synthesized in the human body and does not have a depot in it, but it plays an important role in enhancing immunity and skin barrier functions.
Another important ingredient in fighting oxidative stress is glutathione. It belongs to intracellular defense mechanisms and increases cellular resistance (resistance) to toxins.
Antioxidants also include flavonoids, selenium, coenzyme Q10, etc. It is important to find out which of them and in what ratio you need to take during an individual consultation with a dermatologist and endocrinologist.
