Food things you should know
Ceramide is a naturally occurring lipid component in the skin. It has a barrier function that protects the skin from allergens and other irritations. It can also maintain skin moisture, repair dryness, and resist aging. Therefore, ceramide has been widely used in recent years. Among skin care products, it is even called the “king of hydration.”
Ceramides, also known as ceramides by transliteration, and also known as molecular nails, are a naturally occurring lipid component in the skin that have a barrier function that protects the skin from ultraviolet rays, bacteria, allergens, etc. . It also helps to maintain skin moisture, increase moisture content, and repair dry and cracked skin. Therefore, ceramide has been widely used in skin care products in recent years, and is often used in health foods that seek beauty functions. It is often called the “King of Hydration”. It is said that its water retention effect is comparable to that of hyaluronic acid. The most commonly used supplements today are “Phytoceramides” extracted from plants such as konjac, corn, pineapple, and brown rice.

What are ceramides? Is it oil that is hydrophilic?
Ceramide is a type of sphingolipid, a lipid molecule with a particularly complex structure, consisting of a long lipophilic carbon chain, an amine group, and a sphingosine. . Therefore, the structure of ceramide has both a lipophilic group and a hydrophilic group. Although ceramide is a kind of grease, it has good water absorption properties.
Important components of the cell membrane are like the adhesive between the bricks
Ceramide is an important component of cell membranes and also plays an important role in the sheath of nerves. What attracts the most attention is that ceramide plays an important role in moisturizing and protecting epidermal tissues. If we think of skin cells as bricks, they fit together to build the skin barrier. Ceramides are like adhesives sandwiched between bricks, sealing the walls together to form an effective barrier that not only prevents the skin from losing moisture, but also protects the skin from external irritation.
Ceramide is located in intercellular lipids and has moisturizing and barrier functions
Ceramide is generated with the cell renewal of the skin. The metabolism of the skin refers to the production of epidermal cells from the basal layer, the lowest layer of the epidermis, and then these cells continue to move upward through division, and finally reach the stratum corneum, and finally form exfoliation. Newly born cells initially contain ceramide. When cells rise through metabolism to the stratum corneum, the outermost layer of the skin, ceramides in the cells are released into the intercellular lipids in the stratum corneum, causing the stratum corneum to contain ceramides. 50% of intercellular lipids are ceramide. Ceramide molecules are regularly arranged between cells to form a stacked layered structure. Water is stored between these layered structures. Ceramide forms this lipid layer structure, which gives ceramide a moisturizing effect and barrier. Function.

After the age of 40, the amount of ceramides in the skin is only half that of the age of 20!
According to years of research, as we age, our skin metabolism slows down, resulting in a significant decrease in ceramides in the epidermis.Human experimentIt is pointed out that after the age of 40, the ceramide content in the skin is only about half of what it was in the 20s, which causes various aging phenomena of the skin, such as dryness, fine lines, wrinkles, roughness, etc. Therefore, additional ceramide supplementation is a way to resist the loss trend.

The loss of ceramide leads to the destruction of lipid structure and produces inflammation and sensitive muscle symptoms.
When the reduction of ceramide leads to the destruction of the lipid layer structure, the intercellular lipids cannot effectively support the keratinocytes, resulting in gaps in the keratin layer, resulting in weakened barrier function, dirt and bacteria can easily invade the skin, causing symptoms such as itching and inflammation. Then, the stratum corneum is further damaged, and the skin’s water evaporation intensifies, forming a vicious cycle, leading to dry skin, sensitive skin, and skin problems. Therefore, the ceramide content plays an important role in protecting the skin from external stimuli, retaining moisture, and giving the skin moisturization, firmness and elasticity.
Provides excellent skin moisturizing power. 80% of the moisture in the stratum corneum is locked in by ceramides.
Ceramide, which has excellent moisturizing power, has shown moisturizing ability in many studies, so it is effective in preventing and improving dry skin problems. Usually, the moisture content of the stratum corneum is considered to be between 10 and 30%. If it is lower than this range, the skin is considered to be in a dry state. When the air is dry or the temperature is too high, the moisture in the cuticle evaporates more easily. According to expert estimates, more than 80% of the water in the stratum corneum is held by intercellular lipids such as ceramide, 15% by natural moisturizing factors, and 2 to 3% by sebum. . Therefore, ceramides, which account for the vast majority of them, play an extremely important role in maintaining skin moisture. Studies have also shown that ceramides in the skin also decrease in winter, which is also a major reason why skin is prone to dryness and itchiness in winter.
Helps fight atopic dermatitis
Atopic dermatitis is a chronic skin disease, mostly caused by allergies and various stimuli. Various factors such as eating habits, living environment, genetics, interpersonal relationships, and psychological stress may cause irritation, resulting in eczema and severe itching. The affected area may leak tissue fluid. When it develops chronically over a long period of time, the skin will become rough and prone to aging.
Research in recent years shows that there areatopic dermatitisThe ceramides in people’s skin will also be significantly lower, resulting in a weaker moisturizing function of the skin, resulting in a lower barrier function of the skin, making it easier for external stimuli to invade, thus causing dermatitis. Therefore, replenishing ceramides in the skin is one way to assist in the fight against atopic dermatitis.
It has skin-beautifying effect and makes aging cells self-destruct, effectively combating skin aging.
Ceramides help moisturize the skin, so they have the effect of preventing common skin aging problems such as dryness, wrinkles and skin problems. And because it keeps the skin hydrated, it is considered to have extremely high skin beautifying effects. In addition, ceramide has been found in some studies to have the potential to control cell division and proliferation, maintain normal skin metabolism, and promote the self-destruction of aging cells. In addition, ceramide can also maintain moisture and oil in the hair at the same time, so it has the effect of keeping the hair moist.
How to supplement ceramides? Can be obtained by consuming “phytoceramides”
Ceramide is a relatively new ingredient, discovered in the myelin sheath of nerve fibers in the 1950s. It was not until the 1980s that its efficacy was clarified through research. The main sources of ceramides currently used in food or cosmetics are plants such as konjac and corn, so they are also called “phytoceramides”. Since purified ceramide is quite expensive, many scholars are working hard to research production methods that can effectively and stably produce ceramide raw materials. Ceramides can be found in the following natural food sources, but because the content in food is very low, to effectively absorb them, it may be faster to supplement them with purified functional foods.
Natural foods containing ceramides:Konjac (konjac), brown rice (rice bran), wheat, corn, pineapple, dairy products, soybeans, spinach
Are ceramides safe? Are there any side effects?
Ceramide is a molecule found in the cell membranes of the human body and natural foods, so it is safe and has no side effects in the world record. Unless people with special physiques need to consult a doctor or other experts before using it. Currently, purified ceramide is not available for consumption in Taiwan, so if you see brown rice extract (containing ceramide) or konjac extract (containing ceramide) on the ingredient label, that is correct.
Other important ingredients that are lost with age:
Collagen: reaches its peak at the age of 20 and is easily damaged by ultraviolet rays and blue light
The human body contains a large amount of collagen, which means that collagen has many aspects of effects on human health. From skin beauty, joint health, bone development, and even recent research on the effects of helping muscle growth, preventing hair loss, increasing muscle mass, promoting wound healing, regulating blood pressure, etc., collagen supplements have potential effects. The amount of collagen in the body will gradually decrease with age. After reaching a peak around the age of 20, it will decline all the way. Research in recent years has also shown that modern high-stress lifestyle will also accelerate the consumption of collagen. Ultraviolet rays from the sun, or blue light produced by 3C, as well as free radicals produced by unhealthy lifestyles or stress, will destroy collagen in the body. Hyperglycemia and hyperlipidemia are also considered causes of collagen aging.
NMN: Effectively improve aging phenomena and prevent body function degradation
NMN is the abbreviation of Nicotinamide mononucleotide. NMN is a molecule that occurs naturally in the human body. It is also found in some natural foods and is the precursor of NAD. As age increases, NAD+ will gradually be lost. The NAD/NAD+ content in the human body reaches its peak at the age of 20, and then decreases rapidly with age. By the age of 70 or 80, the NAD/NAD+ content in the body is only one-third of what it was when you were young.
There has been a breakthrough research result on NMN. After 22-month-old mice (equivalent to 60 years old in humans) consumed NMN for a week, their muscle condition was equivalent to that of 20-month-old mice (equivalent to 20 years old in humans). Therefore, it can be said that through short-term NMN investment, the mouse’s physical age has been “rejuvenated” by 40 years! In other papers in the future, studies on the oral administration of NMN to the elderly have also obtained many positive results, such as slowing down the aging phenomenon, improving walking speed, improving grip strength, improving muscle strength, preventing physical function degradation, preventing fatigue and Reduces drowsiness and other effects.
Q10 – Vitamin Q: Coenzyme found throughout the body and has antioxidant effects
Q10 (CoQ10, coenzyme Q10) is a coenzyme distributed throughout the body. It is an indispensable factor for the body to produce energy and also has a strong antioxidant effect. Therefore, it is closely related to heart health, prevention of chronic diseases, protection of brain nerves, enhancement of physical strength, and relief of fatigue. Although the human body can produce Q10 on its own, after the age of 20, the content of Q10 in the body will continue to decrease, especially in the heart and kidneys at the fastest rate!
