The symptoms and severity of skin diseases vary greatly, and there are thousands of them officially named in medicine. They can be temporary or permanent and can be painless or painful. Some are environmental reasons, while others may be genetic reasons. Some skin diseases are milder, while others can be life-threatening.
This article will share how to improve common skin problems in the most natural way, such as acne (acne), acne, atopic skin, sensitive skin, sensitive redness, onychomycosis, etc.
What is the correct concept of skincare?
Let you guess what is the largest human organ? All alveoli in the lungs add up to 70 square meters. The liver is the largest organ in the internal organs. The intestine is the size of a basketball court. If the skin is the size of an adult man Approximately 1.6 square meters, weighing 16% of the body weight, about 10 to 12 kilograms, from the lungs, liver, intestines to the skin, each organ has a claim that it is the "largest", excluding recent discoveries but not The "interstitium" agreed by all experts (the pathology professor of New York University Langone Medical Center estimates that the interstitium accounts for 20% of the body volume, which is equivalent to 10 liters for young adults), from In terms of weight, the skin can be called the heaviest organ.
As the first line of defense and the largest organ of the human body, the skin is always involved in the functional activities of the body's functions, maintaining the unity of opposites between the body and the natural environment, and abnormalities of the body can also be reflected on the surface of the skin. Before talking about how to improve skin problems, we must first understand the skin structure and establish a correct concept of skincare.
The physiological structure of the skin
The skin is roughly divided into three layers: epidermis, dermis, and subcutaneous tissue. The thickness of the epidermis is about 0.03~0.30mm. Depending on the degree of keratinization of keratinocytes, it can be divided into five layers, in order It is the basal layer, spinous layer, granular layer, transparent layer, and stratum corneum. The stratum basale is the most well-known to the general public. The stratum basale is the deepest layer of the epidermis. It consists of a short columnar or cubic layer. The morphological cell composition is the source of epidermal growth. The cells in it continue to divide, gradually migrate outward and produce changes, and finally form the stratum corneum, which provides basic friction, sun protection, and moisturizing functions of the epidermis.
The epidermis is a protective barrier with self-renewal ability, against all kinds of physical and chemical stimuli from the outside, such as dryness, heat and cold, ultraviolet rays, etc., including chemical substances, chemical gases, harmful light, microbes, and bacteria. It provides a defensive barrier and protects the body's water and body fluids from evaporation and loss. This frequent replacement change from the basal layer to the stratum corneum is called skin renewal. When the stratum corneum is damaged by external foreign bodies or environmental factors, the renewal speed will increase to eliminate foreign bodies and repair the skin.
In the structure of the skin, the light stratum corneum has 15-20 layers. Although it is metabolized once every 28 days, not every cell is at the same time.
Therefore, it takes 3-6 months to rejuvenate the skin before it is changed almost once. In addition to the basic anti-friction effect, the stratum corneum is the part that directly contacts all beauty and maintenance products, and has the deepest impact on the use of the product and the beauty of the skin. Some amino acids and their metabolites play an important role in maintaining moisture in the stratum corneum. The stratum corneum contains 15-20% of low-molecular-weight moisturizing factors that are produced by the skin and have the ability to absorb moisture, which is called natural moisturizing. Factor (Natural moisturizing factor, NMF), which makes the stratum corneum maintain firmness and softness of the skin. Natural moisturizing factor (NMF) is the general term for some low-molecular-weight substances (including amino acids) that exist in the stratum corneum and can be combined with water. , Lactate, urea, uric acid, and pyrrolidone carboxylic acid...), NMF can reduce the loss of skin moisture, is extremely water-soluble, accounting for about 10% of the stratum corneum cell matrix. The softness, smoothness, and elasticity of the skin depend on the water content of the stratum corneum. 10%-20% is the most ideal, and the water content is less than 10%, which means dry skin. In short, the moisturizing function of the epidermis and the normal metabolism of cells can keep the skin smooth and beautiful.

What beauty product ingredients can destroy the stratum corneum?
The epidermis is healed by migration, so it is important to retain the moisture content of the stratum corneum and epidermis. The main raw materials that can damage the stratum corneum to retain moisture are surfactants, polyols, and alcohols.
According to the article "J Cosmet Sci. 2020 Jan/Feb;71(2):91-109.) Surfactant (SURFACTANT, also known as surfactant) penetration into the skin, it is pointed out that surfactants are the most widely used It may be the household goods and cosmetics industry, such as the manufacture of washing powder, dishwashing liquid, face and body cleansers, and lotions and creams. However, the extensive use of detergents and cleansers on the skin may cause itching, redness, and dryness. These are called irritation caused by surfactants, which are at least partly caused by the penetration of the surfactant into the skin.
Similarly, according to research, "polyols" are also irritating to the skin. Common ones are phenoxyethanol (PHENOXYETHANOL), ethanol (ETHANOL), benzyl alcohol (BENZYL ALCOHOL), caprylyl glycol (CAPRYLYL GLYCOL), Ethylhexyl glycerol (CAPRYLYL GLYCOL) similar raw materials. They are raw materials with antiseptic function or auxiliary antiseptic function, but they were not registered as "preservatives" but as "humectants" when they were registered. In this way, it can be declared "no preservative", because there is true "no preservative", or in other words, there is no "registered" preservative.
These "hidden" chemical poisons may cause skin irritation due to long-term use, causing hair loss, skin allergies, dermatitis, and other symptoms. Patients will face difficult skin problems.
Application of natural ingredients
Throughout the history of human development, there are historical records of the use of folk medicines on all continents. Doctors, priests, and wizards are very powerful and influential in his community. For a long time, medicine, religion, and botany have been closely integrated in many societies. Today, the relationship between man and nature should be as close as in the past.
India's Ayurveda (AYURVEDA, also known as Life Vedic) medical system medicine is one of the oldest medical systems in the world. Ayurvedic traditional medicine can be traced back to the Vedic era around 3000 BC. It is known for the oldest and recorded comprehensive medical system in the world and is used by countless Indian families today in the 21st century. Ayurvedic medicine is not only a medical system but also represents a healthy lifestyle. The Sanskrit Ayurveda (AYURVEDA) is composed of the words AYUR (meaning life) and VEDA (meaning knowledge and science), so the word Ayurveda means the science of life. According to Ayurveda, human beings should coexist in harmony with the natural world, and disease occurs because this harmony is broken. Restoring this basic balance through the use of nature and its products is the main method and purpose of Ayurvedic medicine. This concept is not only used in the process of treating diseases, but also in the prevention of diseases.
Nowadays, not only does Ayurveda continue to spread, more companies in the application of cosmetics and skincare products are also investing in the research and development of plant effects; the cosmeceutical industry is a growing demand market, especially in Asia. South Korea has been at the forefront of the new generation and most innovative cosmeceutical products. These products include snail secretions, starfish powder, plant extracts, green tea and ginseng, and other ingredients. In view of their increasing popularity in the cosmeceutical industry, scientists have been investigating these extracts and their properties. As a result, it has been found that a variety of natural extracts have anti-aging, anti-tumor, and anti-postpartum fat effects, making it an application ingredient in current cosmeceutical products.
In Taiwan, there are also companies that use the inherent advantages of Chinese herbal medicines and the repeated verification of modern technology to integrate traditional medicine with modern beauty technology, and develop products related to the functions of skincare products based on the overall skincare efficacy, such as anti-aging, moisturizing, exfoliating, and cleansing, Whitening, sun protection, etc. There are even winners who use bitter ginseng pure lotion to develop products that solve skin problems, such as atopic dermatitis and acne.
Bitter ginseng is a common Chinese medicine, (scientific name: SOPHORA flavescens) is a plant of the leguminous Sophora genus. It was first published in the "Shen Nong Materia Medica". It has the name of ginseng but no ginseng. It is distributed in Russia, Japan, and India. , North Korea, North and South provinces of mainland China and other places, grow in areas 1,500 meters above sea level, mostly in hillsides, sandy land, grass slopes, shrubs, and fields near fields. Functions and indications: clearing away heat and dampness, killing insects, diuresis. It is used for heat dysentery, blood in the stool, jaundice, urinary obstruction, red leucorrhea, vaginal swelling and itching, eczema, eczema, skin itching, scabies, and leprosy; external treatment of trichomonas vaginitis. Bitter ginseng has a special smell, and it is generally less used for internal use, and more often for external use to treat the skin. It is a kind of traditional Chinese medicine mainly for clearing heat and removing dampness. Bitter ginseng contains various alkaloids and flavonoids such as genuine, oxidized genuine, and petition, and has always been good external medicine for skin diseases.
Bitter ginseng has been used in beauty and skincare hundreds of years ago, and now it is a cosmetic ingredient favored by major cosmeceuticals. In terms of beauty and skincare, Kusum's rich herbal nutrition can effectively activate the skin, restore skin elasticity, balance skin oil secretion, regulate skin oil and water balance, smooth and purify pores, and make skin regain a firm and smooth touch. On the outside, it restores luster and brightness.
What is the difference between natural vegetable oil and mineral oil?
The key point of why natural plant ingredients have beneficial effects on the skin is the difference between vegetable oil and mineral oil in repairing the stratum corneum; the stratum corneum is like the defense wall of our skin, and the lipid layer in the intercellular space is rich in cholesterol (CHOLESTEROL) Ceramides (CERAMIDES) and fatty acids (FREE FATTY ACIDS) are like cement that builds up the entire city wall. They are important components for maintaining the integrity of the stratum corneum. The repair of the stratum corneum focuses on smoothing the stratum corneum instead of removing it. Cutin, general mineral oil products are covering properties and cannot penetrate the stratum corneum. Only vegetable oils contain fatty acids and waxes, cholesterol, squalene, etc. required by the epidermis. Only by maintaining the integrity of the stratum corneum can it protect the skin, prevent the loss of moisture, and allow the keratin to lock in moisture, so that the skin remains soft and smooth, more elastic and tensioned, and fundamentally solves skin problems.
Ginseng Hydrosol is an example of Chinese herbal medicine used in beauty products. Nowadays, more beauty companies around the world have invested in the development and research of natural products, and more and more herbal plants are widely used in various products. , How to choose natural products instead of chemical products carefully, so that the skin is no longer harmed, will be another issue for consumers.
In the structure of the skin, the sebaceous glands and pores and hair follicles will have some normal flora. If the skin has a small wound, some bad bacteria will proliferate. At this time, it relies on the resistance of the skin to sterilize. The epidermis is healed by migration, so it is important to retain the moisture content of the stratum corneum and epidermis. The main raw materials that can damage the stratum corneum to retain water are surfactants, polyols, and alcohol products; when the stratum corneum is unhealthy, flavors and essential oils are prone to itchiness; therefore, retain moisture and make the stratum corneum stack smooth and watery Very important, this is the first line of defense for the skin. Therefore, how to solve the skin problem, the most important thing is to establish the correct concept of taking care of the skin first, the rest is time, and the effect will be seen.
