Antioxidants − polyfunctional compounds of various nature, capable of eliminating or inhibiting free radical oxidation (FRO) of organic substances by monomolecular oxygen.
Antioxidants that function in the living body (bioantioxidants) play an important role by protecting biological substrates from non-enzymatic oxidation, such as lipids, which are very important in maintaining the hydrolipidic balance of the skin.
Find out in the article on estet-portal.com about the mechanisms of action of antioxidants, the classification of these compounds, as well as their effects on the skin.
Three types of antioxidants
It is rather difficult to classify antioxidants. This is due to the fact that substances of a very different nature have similar properties.

Known antioxidants can be classified into groups according to their solubility:
1) Soluble in water.
2) Fat soluble.
3) Both water-soluble and fat-soluble.
An increase in the antioxidant pool of the cell slows down the aging process
Water-soluble antioxidants work in blood plasma and the intercellular space that surrounds cells. Whereas the fat-soluble − on the cell membrane, which consists mainly of lipids. Those that are both water soluble and fat soluble work both on cell membranes and inside cells as cells contain water.
These antioxidants, using their fat-soluble characteristics, can move into cells and then display their water-soluble character.
How Antioxidants Work
Depending on the principle of action, antioxidants can be divided into the following groupss:
1. Antioxidants that prevent (prevent) oxidative processes. These include antioxidant enzymes produced by the body.
2. Antioxidants that neutralize free radicals by donating an electron to a free radical. In the process, they become free radicals themselves, but with less power. Then this free radical is "neutralized" another antioxidant, and the process continues until the "diluted" the free radical will no longer harm the cells.
Prophylactic and chain antioxidants – the first group work directly on free radicals, which is why they are also called direct antioxidants. There is also a group of indirect antioxidants. These are the ones that stimulate or produce other antioxidants to fight free radicals. Examples of such indirect antioxidants are melatonin and curcumin. What effects do antioxidants have on the skin
Since most antioxidants are produced outside the body and are concentrated in plants, the best way is to consume these plants orally and use cosmetic skin care products that contain antioxidants.
Effects of antioxidants on the skin:
- prevention of the symptoms of aging (wrinkles, age spots),
- optimal moisture retention, which allows you to maintain hydration and maintain elasticity,
- anti-inflammatory effect,
- protection against damage caused by external factors (tobacco , alcohol, environment, etc.),
- the ability to stimulate collagen synthesis, and therefore cell renewal.
Dealing with sensitive, reactive skin prone to couperosis and rosacea: choice of preparations Antioxidants − very useful active ingredients for the production of cosmetics. They interrupt oxidative reactions and prevent the effects of free radicals. On the one hand, they prevent the degradation of natural ingredients (proteins, sugars, lipids) in a cosmetic product. On the other hand, − antioxidants protect skin cells from damage and slow down the aging process.
The discovery of antioxidants and their importance in cosmetology is relatively recent. Research and scientific experiments continue. However, today we can say with confidence that components with antioxidant properties are one of the most important and most necessary in cosmetic formulas. After all, such care products will give not only beauty, but also health to your skin.
