These new products, which combine cosmetics with medicine, work from the inside out to make us more beautiful. So are they just a day cream in tablet form? Or are they something more than that?
“True beauty is inside people.” At least this is true if the well-intentioned comments of our parents, relatives and friends are to be believed. “It’s not what appears on the outside, what’s important is what’s inside each of us.” Anyone who has ever doubted their appearance must have heard this comment. But now, new research reveals that may be true.
Most skin care products promise to make your skin look younger by fighting the effects of wrinkles and other signs of aging. The structure and thus the appearance of the skin depends on several different factors. First of all, there is natural aging, something we are all subject to. The following are the effects of diet, stress, genetics and hormonal influence.
In addition, the skin is affected by external causes, such as damage, corrosive substances, air pollution and microorganisms. Another major source of skin damage is UV radiation from sunlight. Strong exposure to the sun can cause sunburn, and long-term even skin cancer and premature aging (photoaging). Photoaging leads to sagging and the formation of wrinkles on the skin and, additionally, to a greater number of pigmentation spots. The skin is the outer layer of the body, it is its barrier from the outside world. Therefore, it is important to take care of it, not only to look good, but also to stay healthy.

Applying sunscreen is the most common way to protect the skin from the harmful effects of UV radiation, but in practice, we are often exposed to UV radiation even when we do not use sunscreen. . Regular use of nutritional supplements can ensure continuous protection of the skin. The skin consists of several layers. The outer layer, the epidermis, forms the first layer of protection against UV radiation and bacteria. The outer part of the epidermis consists of dead skin cells and contains several substances that neutralize harmful UV radiation before it penetrates deeper into the living layers of the skin. One of these substances is beta-carotene, also known as provitamin A.
Internal solar filter
Carotenoids are natural pigments that are usually found in intensely colored vegetables and fruits. Carrots, apricots and green leafy vegetables such as spinach contain large amounts of beta-carotene and the carotenoids lutein and zeaxanthin. Tomatoes contain high levels of lycopene. Carotenoids perform several functions, and one of them is the protection of the skin from harmful radiation, which has developed a series of studies with this substance. Ingestion of beta-carotene1, actively protects the skin from burns. The protection provided by beta-carotene, as well as mixtures of other carotenes, is comparable to that provided by a sunscreen with a protection factor of 2 to 4.
In addition, beta-carotene protects the skin from premature aging caused by chronic sun exposure. UVA radiation affects some enzymes that can destroy collagen, the main component of the skin. Scientists from DSM Nutritional Products discovered that beta-carotene prevents the upregulation of these enzymes by UVA radiation. It has also been shown that beta-carotene reduces the formation of harmful oxygen radicals, i.e. singlet oxygen, by UVA radiation, reducing oxidative stress in the skin.
They also discovered that beta-carotene is important in maintaining normal skin function, as it helps skin cells to differentiate, that is, to develop their normal function. When combined with other carotenoids such as lutein, zeaxanthin and lycopene, beta-carotene can offer even greater protection. Various human studies have shown not only a reduction in burns, but also an improvement in skin conditions such as roughness and peeling based on the use of carotenoid and antioxidant mixtures. 2
In addition to carotenoids, well-known vitamins such as C and E help protect the skin and maintain its health. Vitamins C and E act as antioxidants, i.e. they are capable of neutralizing very aggressive oxygen molecules. The creation of these “free radicals” is stimulated by UV radiation, and vitamins C and E are also called “macrophages” because of their free radical neutralizing properties.
Vitamin C also plays an important role in the stiffness of the skin, participating in the synthesis of collagen, as well as blood vessels and tendons. A significant deficiency of vitamin C results in scurvy, a condition that literally causes loose tissue, since the necessary collagen does not have the proper structure.
CoQ10 for energy metabolism
Coenzyme Q10 (CoQ10) is a natural vitamin-like compound found in most cells in the human body. CoQ10 is a key nutrient, as it is involved in assisting in various metabolic processes and plays a fundamental role in energy production in the mitochondria, the cellular powerhouses of energy production. In addition to its role in energy metabolism, CoQ10 is also a powerful antioxidant that protects mitochondria from damage caused by free radicals.
Exposure of the skin to UV radiation, cigarette smoke and other air pollution agents creates oxidative stress and causes mitochondrial damage. Consequently, deficiencies in the energy production process accumulate over time and cause skin cells to age prematurely. CoQ10 can slow skin aging by protecting the integrity of mitochondria and maintaining the skin’s energy metabolism. As we age, the body’s ability to synthesize CoQ10 declines. Therefore, it is more important to ensure an adequate supply of CoQ10. 3
The health benefits of polyunsaturated fatty acids, known as PUFA, are mainly related to cholesterol levels and the prevention of cardiovascular disease. But PUFAs, which are widely found in vegetable oils and fatty fish, also play an important role in skin hydration.
Skin dehydration is another important factor in skin aging, along with UV radiation and loss of firmness. Therefore, PUFAs fit well into the concept of inner beauty. They are often found on the market in the form of fish oil capsules, but the unpleasant taste and smell of this type of capsule represent major disadvantages.
Green tea contains high concentrations of EGCG, a catechism that has a wide variety of beneficial properties for health, including skin. 4 It is a radical scavenger, in the same way as vitamins C and E; It has an anti-inflammatory effect and contributes to the recovery of the skin.
