When it comes to “hormonal face”, you need to know the structure and function of the skin first. The skin is a natural protective barrier on the surface of the body, with a “sebaceous film” on its surface, which prevents the loss of water, electrolytes and other substances in the body, as well as the invasion of harmful or unwanted substances from outside. The keratinocytes and cells of the skin form a “brick wall-like structure” by means of lipids and natural moisturizing factors. The keratin-forming cells are the “bricks”, the intercellular connections are the “reinforcement”, and the intercellular lipids are the “mortar”. Together, they form a natural protective barrier for the body, which is the famous “brick wall theory” proposed by Peter in 1983. First, let’s understand the basic concept: sebaceous membrane: it is composed of “oil” secreted by sebaceous glands (the main component is squalene), “water” secreted by sweat glands, and “natural moisturizing factor” secreted by epidermis. “The three components are Brick wall-like structure: The epidermal stratum corneum cells are like “bricks”, while the “lipids” (mainly ceramides) and “natural moisturizing factors” between the stratum corneum cells are like “mortar”. The “lipids” (mainly ceramides) and “natural moisturizing factors” between the stratum corneum cells are like “mortar” that keep the stratum corneum cells together. The lipids in the “sebaceous membrane” on the surface of the skin and the lipids between the stratum corneum are different in origin and composition. The former is derived from sebaceous gland secretions and its main component is squalene, while the latter is derived from keratin-forming cells and its main component is ceramide. If the skin barrier is damaged, there will be a decrease in the skin’s moisturizing function and symptoms such as dryness, flaking, itching, erythema and chapping. When the epidermis is intact, commensal bacteria such as bacteria, fungi or viruses on the skin surface are not pathogenic. When the epidermis is damaged (i.e. the skin barrier is destroyed), these commensal bacteria can enter the dermis and trigger an immune inflammatory response. Look again, how do hormones destroy the natural barrier of the stratum corneum? The hormones we usually refer to are glucocorticoids, and the initial use of these drugs rapidly whitens the skin (thanks to the powerful anti-inflammatory and vasoconstrictive effects of hormones, one level a day, which is indeed tempting) and hydrates and refines it. However, prolonged topical application will lead to thinning of the skin (inhibition of proliferation and differentiation), reduction of barrier function (reduction of sebum synthesis, destruction of intercellular connections), skin inflammation (immune suppression, dysbiosis, infection, folliculitis), skin becomes thin, fragile, red, dry and itchy, gradually losing its defense function against the outside world, vulnerable to injury, and thus becoming dependent on hormones, which is difficult to get rid of. For all kinds of hormone creams, in fact, comrades’ eyes are still shining, however, for those mixed in skin care products, packaged as various “magic tools”, “face masks” endorsed by stars, “pure herbal formulas The “skin problems”, “skin problems star”, “N days let you white” and so on skin care products, it is estimated that you can not tell the difference. The advertisement is too tempting, but the reality is too cruel. This kind of “skin care products” once used on the skin super good, white, red, stop using on the bad (hormone rebound). So you can only continue to use, can not stop. But long-term use has led to thin, dry, sensitive, itchy skin and even red blood, wine slag-like lesions. This is one of the reasons why hormone dependent dermatitis has increased clinically in recent years. What kind of skin care products can repair the skin barrier? In a word, skin care products that mimic normal sebum are the best choice. In natural sebum, the ratio of ceramide: free fatty acid: cholesterol is 1:1:1. (Although lanolin contains 10% ceramide, products with insufficient purity and mixed substances are prone to allergy instead). Fat accounts for 10% of the dry weight of the stratum corneum, and sebum forms a plate-like structure. The closer to this ratio and shape, the more it helps the skin repair. Therefore, medical skin care products must have a greater advantage than ordinary moisturizers. Hyaluronic acid – hyaluronic acid, the new darling of the beauty industry. Its cross-linked polymer can form a three-dimensional mesh structure that evenly covers the surface of the skin, forming a breathable film that can strengthen the skin barrier function, reduce the flow of water, but also resist the attack of dust and haze (anti-PM2.5 pioneer has a wood) on the skin. The state of skin hydration is exceptionally important for barrier repair, so doctors will tell you to moisturize, moisturize, moisturize. Whether it’s water or cream that you replenish at any time, make sure to keep your skin hydrated at all times. Of course, all kinds of big sprays are only temporary relief, so don’t forget to replenish the cream. What should we do when we have “hormonal face”? In addition to the reduced barrier function of the skin, “hormonal face” has no resistance to mechanical stimulation, physical stimulation and microbial invasion, which makes the face very susceptible to allergic dermatitis, and the expansion of capillaries makes our face often appear scarlet, or even “scarlet”. “The swelling of the face when exposed to heat, dryness, cracking, itching and stinging make us miserable. First of all, we have to gradually quit hormone reuse; in addition, strengthen the skin barrier reconstruction is very important, can take a trilogy: moisturizing – skin care – isolation; again for the long-term use of hormones resulting in conditional pathogenic bacterial infections, to symptomatic treatment, there are follicular worms to kill the follicular worms, there are furunculosis infection antifungal, etc.; finally Lastly, we have the killer, Chinese herbal medicine treatment in the treatment of “hormonal face” is indispensable and often a constant winner, but only if an experienced doctor treats it with evidence. Finally, we would like to remind you that in the process of choosing skin care products on a daily basis, you should be careful with the skin care products and cosmetics sold in beauty salons, and consumers who have already developed inflammation should immediately stop using cosmetics, go to the hospital to receive treatment in a timely manner, and choose medicinal cosmetics with reliable ingredients under the recommendation of a doctor, so as to say goodbye to “hormonal face” and raise your The “face” value.
