Trehalose, the Sugar of Life, is a Natural Skin Barrier Ingredient

People take good care of their skins every day, doing all kinds of cleansing, anti-aging, whitening, and applying facial masks, but what they get is a face that is prone to redness, itching, peeling, and even crazy oily acne.

Why is this the case? The most important reason is: the skin barrier is damaged!

The skin barrier is composed of the sebum membrane and the stratum corneum, just like a city wall, but the thickness of the sebum membrane is only 0.5 microns. Excessive cleaning, frequent exfoliation, and indiscriminate use of some skin care products that are not suitable for you will cause the sebum membrane to become thinner and the stratum corneum to be damaged.

Once the skin barrier is damaged, it is like a city wall being knocked down. Not only can moisture and nutrients not be retained, but harmful substances will also invade the deep layers of the skin, resulting in various "rotten faces". Don't smear it at this time! The first task is to repair the skin barrier to prevent the skin condition from continuing to deteriorate.

The natural barrier ingredient - trehalose

Trehalose, as a natural sugar, can form a special protective film on the cell surface to protect its internal structure in harsh environments such as high temperature, high cold, dryness and dehydration. It is a very stable non-reducing disaccharide.

Trehalose is very stable and is known as the "sugar of life" in the scientific community. It is widely found in lower plants, algae, bacteria, fungi, insects and invertebrates. For many living organisms, the presence or absence of trehalose means life or death.

1. Targeted barrier repair

40% -50% of the sebum in the stratum corneum is composed of ceramide. Trehalose replaces other components in the stratum corneum of damaged skin, allowing ceramide molecules to be arranged in their normal way, stabilizing sebum, delaying water evaporation, maintaining the osmotic balance of the stratum corneum, protecting the normal osmotic function of the skin, and thus repairing the skin barrier.

2. Protect cell membranes

Trehalose molecules contain multiple hydroxyl groups and polar groups, which can replace water molecules when cells are dehydrated. Through the hydrogen bonds formed by trehalose's -OH and phospholipid PO2-, lipid bilayer fusion and material leakage are inhibited, thereby protecting the stability of cell membrane structure and function.

3. Strong water lock and moisturizing

Trehalose molecules contain multiple hydroxyl groups and polar groups, which can form hydrogen bonds with water molecules in the surrounding environment and firmly bind water molecules; trehalose and sodium hyaluronate are both sugar substances and can be combined with each other. The macromolecular polysaccharide sodium hyaluronate promotes the uniform distribution of small molecular disaccharide trehalose, promotes its absorption, and maintains the moisturizing effect for a longer time.

4. Anti-UVB damage

Remove OH· free radicals generated by B and A rays, making cell DNA less likely to mutate. Experimental studies have shown that 10MMOL/KG of trehalose can allow living cells to withstand 4.3 times the normal dose of B and A rays. Trehalose can effectively protect DNA from damage caused by UVB and play an anti-photoaging role.

Due to its powerful repair effect, trehalose can be used in the field of medical beauty repair.
