What Are The Benefits Of Ceramides For Skin?

 

Ceramide powder is a type of phospholipid with a ceramide backbone, primarily consisting of ceramide phosphocholine and ceramide phosphoethanolamine. Phospholipids are the primary components of cell membranes. Ceramides make up 40% to 50% of sebum in the stratum corneum.

Ceramides, a water-soluble lipid substance with a structure similar to that of the stratum corneum, help maintain skin hydration.

 

 

1. Natural extraction
Initially, ceramides were extracted from nature, mainly from the brain nerves of mammals (cows, horses, etc.).

 

However, due to the presence of pathogenic factors, most scenarios cannot be applied, and the extraction targets gradually turn to plant cultivation (corn, konjac, etc.).

 

2. Artificial synthesis
The ceramide ingredients in most skin care products are mainly artificially synthesized.

 

There are currently six types of ceramide that can be synthesized. They are structurally similar to natural ceramides, but there are still some differences, which may cause them to not be accepted by their own intercellular matrix after entering the stratum corneum, making it difficult to exert their moisturizing and anti-aging effects.

 

3. Microbial fermentation
Selecting yeast to ferment under certain conditions to obtain phytosphingosine, and then adding fatty acids to synthesize ceramide substances is a commonly used method for preparing ceramide in recent years. The structure of ceramide produced by microbial fermentation is similar to the structure of ceramide in the human body.

 

 

Pure ceramide powder are the name of a large class of ingredients. It is composed of a sphingosine group and a fatty acid linked by an amide bond. However, the structures and carbon chains of fatty acids vary widely. Sphingosine also comes in several types. Therefore, the ceramides they consist of are also very different.

 

 

1. Ceramide 1:
We can see that the biggest feature of ceramide 1 is its long molecular chain. Ceramide 1 is a long-chain ceramide whose molecules can span the bilayer, making the structure more stable. It is precisely because of this characteristic that ceramide 1 only accounts for 1.1% of the stratum corneum.

 

2. Ceramide 2:
It can improve the sebum film while inhibiting the secretion of active sebaceous glands, balancing the water and oil of the skin. It has the ability to enhance the self-protection function of the skin similar to ceramide 1. Although it is high in the skin, it is not easily lost, and supplementing it is of no use. .

 

3. Ceramide 3:
Experiments have shown that ceramide 3 with phytosphingosine (P) as the bottom chain is relatively easy to lose. At the same time, ceramide 3 accounts for 22.1% of the stratum corneum, making it the largest ceramide.

 

Without ceramide 3 for skin, the structure of intercellular lipids cannot be maintained. Supplementing ceramide can repair damaged intercellular lipids and strengthen the cuticle barrier. So generally speaking, if we supplement ceramide 3 with phytosphingosine as the base chain, the effect will be better.

 

 

1. Moisturizing:
Ceramide is the main component of the lipids in the skin's stratum corneum, which can help repair the skin barrier and make the skin soft and shiny.

 

However, as we age, ceramides gradually decrease, and the skin will become dull and dry without it. The close connection between ceramide and barrier can also help improve the skin's water-holding capacity and increase skin elasticity.

 

2. Protective Barrier:
Sufficient ceramides in the skin can resist external stimulation, but if they are missing or absent, the skin loses its natural protective function and loses its ability to defend against all external physical and biological harm.

 

3. Anti-allergic:
This is good news for thin-skinned children's shoes. Best ceramides can help thicken the stratum corneum, improve the tolerance of the entire skin, protect against the intrusion of harmful external substances, avoid sensitivity and repair red blood filaments.

 

 

4. Anti-aging:
During the aging process of skin, lipid synthesis decreases and the ceramide content in the stratum corneum decreases. The characteristics of skin aging are:

(1) The skin is dry, flaky, rough, and loses its luster.
(2) The stratum corneum of the skin becomes thinner, wrinkles increase, and elasticity decreases.

 

The use of ceramide can increase the ceramide content in the stratum corneum of the epidermis, which can improve skin dryness, desquamation, roughness and other conditions.

 

At the same time, ceramide can increase the thickness of the epidermal stratum corneum, improve the skin's water-holding capacity, reduce wrinkles, enhance skin elasticity, and delay skin aging.

 

5. Anti-allergy:
Ceramides can help thicken the stratum corneum, improve the tolerance of the entire skin, protect against the intrusion of external harmful substances, avoid sensitivity, and repair red blood filaments.
