The network is gaining popularity in the practice of home -made cream for face fat. Allegedly, such a cosmetic product is both more useful and more effective than their industrial analogues made mainly from plant materials. We decided to check if this is so.

Quantity posts On the benefits of beef fat and video instructions on its preparation calculated by dozens - in YouTube, Tiktok, Instagram. One of the global popularizers of such cosmetic care - Nary SmithActively using the image of Tradwife (Traditional Wife, “Traditional Wife” - English), more than 11 million subscribers. Beef fat cream can easily be found on popular marketplaces. How They say In the publications, supporters of natural cosmetics, such a cream contains antioxidants, necessary acids, vitamins A, D, E and K. Moreover, it is reported that the antibacterial and anti -inflammatory properties of beef fat help to reassure redness and facilitate states such as eczema and psoriasis. Recommend Use it from acne. Vegetable oils often declared harmful to the skin and body as a whole. Interestingly, that Trend It concerns not only cosmetic care, but also, in general, rejection of vegetable oils: for example, beef fat as a more healthy alternative to vegetable oils Promotes famous readers The “verified” conspiracy therologist Robert Kennedy Jr., recommended by US President Donald Trump for the post of Minister of Health.

The variety of jars and bubbles in pharmacies and stores can create the impression that cosmetic ingredients are an incredible amount. However, after a careful study and comparison of their compositions, it becomes clear that this position is not entirely true: some unique components made into the name appear in a very small amount, and the main composition is largely similar. Authoritative private clinic Cleveland gives a list basic components of cosmetic products, in which there are only 11 items. Popular scientific resource Healthline Analyzes True, it includes much more positions in their list and components that have not shown the proper level of efficiency during the tests. The vast majority in this list are plant products (including synthesized during production). Few products of animal origin are goat and cow's milk, but the first has only limited evidence of usefulness, and the second, unfortunately, does not possess them at all.

The composition of beef fat is enough modest, and parts of the components declared by fans of home cream are not in it at all. The cup of fat contains 0.41 mcg selenium, 5.54 mg of vitamin E, 102.09 g of saturated fatty acids, 85.69 g of mono -saturated and 8.2 g of polyunsaturated.

Selenium is important element For the health of the skin and the body as a whole. However, the skin can only absorb it with Two conditions: firstly, in the form of its connection (for example, Selena sulfide), and secondly, only damaged skin has this ability. If the integrity of the skin is not broken, then applying a product with selenium will not bring any effect.

Vitamin E and fatty acids at the same time really can To absorb through the skin. However, in addition to these substances, there is nothing in the composition of beef fat, therefore, it is worth considering it a source of many compounds useful for the skin. Moreover, their ratio is non -optimal. Zakiya Rakhman, professor of clinical dermatology at the School of Medicine University of Stanford, Explains: Moisturizing facial creams should have a high percentage of the content of polyunsaturated fatty acids, in particular linoleic, and low - mononed oleic fatty acid. In beef fat, the opposite is true: only 3% of linoleic acid and 47% Oleinova. Such a proportion will not have a significant moisturizing effect.

Moreover, despite the promises of fans of beef fat, it is unlikely that it will work to get rid of acne with his help. The fact is that beef fat is extremely similar to the skin, which our skin produces on its own, and can lead to blockage and then inflammation of the sebaceous glands. Member of the American Academy of Dermatology, Dermatologist Maya Tosani inclined To consider that rubbing beef fat on the skin of the face will rather cause acne than contribute to its cure. Her colleague at the Academy and a member of the editorial board of the authoritative scientific publication "Clinical and aesthetic dermatology" Ava Shamban Turns The attention is that in terms of comedogenicity (that is, the ability to clog the channels of sebaceous glands), beef fat is estimated at two or three points of five possible. In other words, such a complication will occur in about half of the consumers using it.

Another alarming feature of beef fat - it Raises Photoshensitization, that is, the sensitivity of the skin to ultraviolet radiation. This Fraught An increased risk of sunburn, allergies in the sun, the appearance of age spots and accelerated skin aging. Other polyunsaturated fatty acids, as well as some essential oils (for example, bergamot oil) and retinoids (vitamin A) oil, have such a feature. Accordingly, when using cosmetics with such ingredients, the skin will require additional protection from the sun. And making beef fat the only remedy in the ritual of face care will not work.

In response to the gaining popularity, the tendency to use animal fat in the cosmetic industry, American scientists tried conduct metaanalysis of existing scientific data. In addition to beef fat, they were also interested in rams. Specialists focused on finding answers to five questions:

Does the composition of the fat make it more suitable for use on the skin?
What is the advantage of using skin fat?
Does fat show therapeutic properties in skin diseases?
What are the side effects of fat on the skin?
Is the use of fat for the environment safe?

Scientists analyzed 19 articles describing comparative studies in humans and animals. It turned out that in general, rams and beef fats are permissible to use on the skin - however, with reservations about photosensitization and comedogenicity. Plant fats, such as pumpkin or linseed oil, moisturize the skin more effectively than animals. At the same time, for people suffering from psoriasis or atopic dermatitis, animal fat can become an additional ingredient in complex emulsions to moisturize the skin. Animal experiments showed that animal fat can have an irritating effect for the skin and eyes, however, long -term adverse consequences in the form of teratogenicity (impaired embryogenesis process, which leads to the occurrence of congenital malformations in offspring) or genotoxicity (toxicity in relation to the genetic material of the cells). Finally, scientists also found the answer to the question of ecology: animal fat does not threaten the existence of coral reefs, but harmful to marine animals, that is, its use in cosmetics worsens the state of the environment. Experts summarize: in general, animal fats can be used in the cosmetic industry as an additional moisturizing component, but they have not yet found any other properties (for example, anti -aging or anti -inflammatory).

Dermatologist Anil Charm Offers Those who intrigued the trend in Tiktok and who suffer from eczema or extreme dry skin, try to use beef fat as follows: a portion the size of the smallest of the smallest denomination in the evening into the skin of the elbows or knees, and rinse thoroughly in the morning. If there are no undesirable effects, then you can use beef fat once or twice a week, but not more often to avoid clogging of pores, and it is on the recommended skin.

Other experts are even more wary of beef fat. Dr. Ava Shamban Turns Attention to the fact that beef fat may contain pathogens representing a risk to humans. Her colleague Joanna Fleming worried It is not safe to use beef fat on damaged skin, as bacteria can get into it. Moreover, beef cream of beef fat cannot be stored as long as industrial analogues, especially in a wet and warm bathroom. Most experts agree that at the moment, there are sufficient funds with the studied composition and proven effectiveness on the market cosmetics, so you should not conduct experiments with the preparation of beef fat creams at home.

Finally, supporters of beef fat appeal to its naturalness. However, firstly, vegetable oils (for example, coconut, pumpkin or olive) are also natural, and secondly, not all natural is useful. Chemist and pharmacist Benjamin Knight Fuchs Curses This analogy: “Koroni manure is also natural. Like such toxic substances as mercury, lead and arsenic, which have been used throughout history. But this does not mean that they are effective or useful ingredients for skin care. ”

Thus, despite the statements of influensers and ordinary users from Tiktok, beef fat cannot be considered an effective cosmetic product. Due to his comedogenicity, he will rather provoke rashes than Acne will cure. Animal fats as a whole cope with moisturizing the skin than vegetable ones. Moreover, beef fat increases photosensitization, which means that after it it is necessary to use sunscreen creams to avoid additional skin problems. Experts agree that the cosmetic industry has much more reliable and effective formulas for care. In the best case, beef fat can be left as a means of caring for elbows and knees, but in no case should be included in everyday care.
