Chemical properties of zinc oxide. Application of zinc oxide in cosmetology and medicine. How to use zinc oxide for acne

Zinc dioxide is an almost water-insoluble white or colorless crystalline powder. It is very widely used in industry, but the properties of this compound make its use in cosmetology possible and desirable. Zinc oxide is found not only in budget products for facial skin, but also in quite expensive preparations, where the degree of its purification is much higher. From this we can draw a paradoxical conclusion: not all chemically synthesized compounds are potentially dangerous; the harm from them is more hypothetical than real.

Main characteristics

In this section, we usually provide brief physical and chemical properties of a particular substance used in cosmetology, but in this case this is inappropriate. The fact is that zinc oxide is a binary (consisting of two elements) substance, information about the intricacies of which you hardly need. But the effect on the skin of the face, features of practical use, potential harm and the best drugs that can be bought at the pharmacy - all this will be interesting from a practical point of view.

What to buy?

Zinc oxide is one of the most popular ingredients in cosmetology, at least in its budget and mid-range segments. Its effect on the skin of the face is practically free of side effects, and harm to health, theoretically possible, can occur only in exceptional cases.

Budget cosmetics (up to 1000 rubles):

Golden lifting – cream for the skin around the eyes (Grandma Agafya’s recipes, 50 ml / 85 RUR). You can’t call this product an elixir of youth, but you can get rid of several wrinkles with its help. An important advantage of the drug is its humane price.

Matt Control Oil-Free Foundation (Lumene, 30 ml / RUR 630). A good and not very expensive foundation. It successfully fights enlarged pores and oily shine. Does not contain parabens.
AC Control BB Cream SPF 30 (Tony Moly, 35 ml / 1000 RUR). The effect of this cream on the skin is very diverse: normalizing the functioning of the sebaceous glands, getting rid of puffiness, evening out the color and structure of the skin. The composition contains extracts of rice, mallow, blueberry and lemon.

Mid-level cosmetics (from 1000 to 2500 rubles):

CC Cream “Perfect Radiance” (Erborian, 15 ml / RUR 1,700). A good foundation from a little-known brand in our area. It successfully fights the first signs of aging, but given the high competition in this price segment, we cannot recommend it unconditionally.
Beyond Perfecting (Clinique, 30 ml / RUR 2,100). A “2 in 1” product for all skin types: foundation and concealer. Contains moisturizing, anti-aging and regenerating components. It has a very delicate texture and provides a long-lasting cosmetic effect.
Photoactive Sun Veil SPF 15 (Ren, 50 ml / RUR 2,500). An exceptionally effective sunscreen that protects the skin from damage from UVA/UVB rays. In addition, the product slows down the natural aging process and fights free radicals.

Top cosmetics (from 2500 rubles):

Compact foundation (Annemarie Borlind, 10 g / 2600 rub.). Long-lasting and skin-safe with additional UV protection. It contains only ingredients that are safe for health, but the price, frankly speaking, is disappointing.

Prevention+ Daily Ultimate Protection Moisturizer SPF 50 (Image Skincare, 91 g / RUR 2,800). A very effective moisturizer with the highest possible UV protection. The composition contains stem cells, photosomes, thiotein, erythritol and hyaluronic acid.
Crema Protettiva Calmante (dr.Kraut, 500 ml / 5600 RUR). This cream can probably be found at a more affordable price, but in any case it is one of the most expensive. On the other hand, the professional orientation of Italian cosmetics from dr.Kraut and its absolute quality do not require additional recommendations.

Review from a cosmetologist

The effect of this compound on facial skin is ambiguous. On the one hand, most researchers agree that the harm of zinc oxide is more hypothetical than real. On the other hand, its chemical properties are such that neglecting the manufacturing technology can theoretically lead to pronounced side effects for the consumer. Therefore, I do not recommend cosmetics with ZnO for the care of infants, even if the manufacturer is confident in its complete safety.

Zinc oxide based ointment stands out as one of the best allies to protect your facial skin. Thanks to its amazing properties, it is able to protect against sun rays to avoid the appearance of wrinkles. We'll find out how to use it further.

Zinc oxide is a chemical compound most used in dermatology. It can be found in the form of a white powder with a fine texture that has no odor. In most cases, in the form of Lassar cream.

Lassar paste plays a key role in skin care as it can treat certain diseases because it promotes cell development. Thus, Lassar cream directly affects the synthesis of collagen and protein.

Properties of zinc oxide for facial skin

Among the main properties are the following:

1. Anti-aging

Collagen is the most important element to ensure skin elasticity. Collagen is produced naturally by the body, but can only be synthesized with the help of zinc and other essential minerals. Additionally, as we age, collagen production will decline. Zinc oxide helps speed up the reconstruction of connective tissues.

2. Sun protection

Zinc oxide as a sunscreen can protect the skin from UV radiation and prevent premature aging of the dermis, tissue damage and dehydration.

The reliability and strength with which a product prevents sun damage depends on the amount of zinc oxide used in the product. The percentage of zinc oxide varies widely, and will determine the final percentage level products reported as "SPF". In sunscreens, the percentage of zinc oxide is typically around 25 to 30 percent. In products like BB creams and facial moisturizers, the percentage (and thus coverage) tends to be lower, around 10 to 19 percent.

3. Personal hygiene

Unpleasant odor on the feet can be eliminated with Lassar ointment. This happens because it prevents the spread of bacteria and fungi on the body. It also helps to close the pores and reduce the occurrence of excessive sweating that is generated in the feet.

Does zinc oxide help with stains?

With the help of zinc oxide, uncomfortable spots caused by the damaging effects of sunlight, such as red spots on the face, melanosis or others, disappear. It is important to note that in case of damaged skin, zinc oxide facial should be used at night and during the day to prevent adverse reactions.

What are the advantages of oxide

Zinc oxide has been found to have the following benefits:

Helps reduce skin inflammation associated with rashes, allergies, or irritations (including diaper dermatitis).
Has the properties of a broad spectrum sunscreen that prevents sunburn (even for sensitive skin).
Provides protection against skin cancer/neoplasms (basal cell carcinoma).
Helps heal wounds and prevent bacterial infections.
Aid in recovery from burns and tissue damage.
To remove blackheads and pimples, you can also combine it with other ointments.
Store the supplied moisture in dry skin.
Reduces dandruff.
Helps in the treatment of warts.
Reduced inflammatory dermatoses (including rosacea).
Treatment of pigmentation disorders (Melasma).
Preventing skin aging.
Improving collagen synthesis and formation of new connective tissue.
Getting rid of diaper rash.

Since zinc oxide is not soluble in water, it must be combined with a carrier agent that is more effective. Commonly added to mineral sunscreens, moisturizers and balms.

Some lotions or creams contain zinc oxide.

How to use zinc oxide for acne

Zinc oxide is beneficial to use for acne to reduce these skin problems that can affect certain ages in our lives.

To treat acne, zinc oxide is usually combined with other anti-inflammatory or antibacterial substances, including antioxidants, zinc gluconate or zinc sulfate, and sometimes antibacterial agents. Together, these elements help reduce the severity, duration, and pain of blemishes, pimples, and cystic/hormonal acne outbreaks.

Antimicrobial/antibacterial properties associated with zinc oxide acne treatment:

reduces inflammation, caused in response to bacteria that cause acne and clogged pores.
regulation of sebum production.
For severe and persistent acne, a dermatologist will sometimes prescribe antibiotics to prevent bacteria from clogging the pores. However, research has shown that acne-related bacteria may become resistant to treatment. Antibiotic acne treatments also tend to cause side effects such as redness, sensitivity to sunlight, dryness and flaking. The good news is that treatment with zinc oxide can still be beneficial even for those with antibacterial-resistant acne.

Using Zinc Oxide for Feet

Using zinc oxide for feet is very simple. You just have to wash your feet and dry them thoroughly. The next step is to apply Lassar paste; its properties will do the rest of the work.

Thanks to the antifungal properties of zinc oxide for nails, you can get rid of this problem quickly.

In what form is it better to use zinc oxide?

Zinc oxide can be used as a cream, ointment, powder, and aerosol. Be sure to consult your doctor before using any type of zinc oxide. Many manufacturers now provide any zinc oxide. The type usually reflects the function and how to use it in treatment.

Zinc oxide is the most commonly used for cream. We can find a creamy zinc oxide product and usually has some benefits for the skin, especially to help with skin problem such as sunburn, wounds, ulcers, UV protection, etc.

Helps in the treatment and prevention of skin diseases and diaper rash. Ointment with zinc oxide works with the problem of dry skin and prevents diaper rash. Also used to protect skin from irritation. It is better to use before bedtime.

3. Powder

Zinc oxide powder is an astringent and works slowly to heal the skin from UV rays. Zinc oxide is an organic compound that is liquid soluble and is primarily used for numerous skin problems.

Part of natural skin regeneration. Suitable for sensitive skin. Also used for UV protection.

Introduction

You are planning to go to a seaside resort in the summer. It goes without saying that you should definitely visit the beach. In addition to a sun lounger, umbrella, inflatable rings and other small items, you also need sunscreen. You go to a specialty store and buy this product. And at home the idea suddenly came to mind to look at its composition. And on the part of the package where it is written, the name of an unfamiliar substance caught your eye - zinc oxide. Many people will want to know as much as possible about him. That’s why today’s article is dedicated to this connection.

Definition

Zinc oxide is a colorless crystalline powder having the formula ZnO. Some sources may call it zinc oxide.

Zinc oxide: properties

It does not dissolve in water. The oxidation state of zinc in this compound is +2. If the substance is heated, it will acquire a yellow tint instead of the usual white (photo). And at a temperature of 1800 o C, zinc oxide also sublimates. It is also known as a direct gap semiconductor, whose band gap is about 3.4 eV. Zinc oxide is an amphoteric substance, i.e. when reacting with an acid, it forms salts, and with an alkali, various complex hydrozincates. If this oxide is immersed in an aqueous solution of ammonia, this will result in the formation of ammonia. It can also fuse with alkali or any metal oxide to form zincates, and with silicon or boron oxides - silicates and borates, respectively.

Receipt

Zinc oxide can be obtained in several ways: from the natural mineral zincite, by burning zinc vapor in an oxygen environment, by thermally decomposing zinc acetate/hydroxide/carbonate/nitrate or burning the same sulfide, using hydrothermal synthesis, as well as by treating sludge and dust in metallurgical plants.

Application

It is used as an activator for the vulcanization of rubber and a catalyst in the synthesis of methyl alcohol. In paints and enamels, zinc oxide was a white pigment, but it was soon replaced by titanium dioxide. It is a filler in rubber, plastics, paper and cosmetics. In the medical field, it is a powder and one of the components of antiseptic ointments; in industry, it is an additive to animal feed, as well as an ingredient in rust converters. Due to its photocatalytic activity, the substance is used to create self-cleaning surfaces and bactericidal coatings on hospital walls and ceilings. It is not currently used to purify water in this way. In addition, the powder of this oxide is a medium in which powder lasers work well. With his help, the world was replenished with an invention called the blue LED. If nanostructures are based on zinc oxide, then they can be used as gas and biological sensors. Due to its characteristics, it is also useful in pharmaceuticals. Zinc oxide is used to create abrasive toothpastes and cements (dentistry), tanning creams and materials for procedures (cosmetology), electrical cables, artificial leather and rubber products (surgery). The tire, paint and varnish, oil refining industries, as well as the production of ceramics and glass, cannot do without it.

Conclusion

Zinc oxide has a sufficient number of important characteristics, while it is toxic, but still successfully finds application in industry and everyday life due to its interesting properties.
