What are the most effective ingredients for moisturizing?

I don't know if you have such confusion, that is, you know some good celebrity skin care products, and the advertisements may also be very tempting, but you are worried about whether it is really suitable for you. Today, I will carefully introduce the efficacy of some of the more important skin care ingredients in the skin care process, so that you can choose the skin care products that are suitable for you according to your actual situation.

 First of all, moisturizing and hydrating are two different concepts.

 Hydration: It directly replenishes the moisture needed by the stratum corneum cells of the skin.

Moisturizing: It forms a protective film on the surface of the skin to prevent the loss of moisture from the surface of the skin.

Therefore, hydration ≠ moisturizing, but both are indispensable, and both work at the same time to better provide moisture to the skin.

 Secondly, moisturizing is more important than hydration.

Using hydrating products can moisturize the stratum corneum of the skin, which helps maintain the skin's "natural barrier", which in mind will make the skin look plumper and refined.

However, all hydrating products can only moisten the outermost stratum corneum of the skin, and cannot really enter the deeper layers of the skin. So once the moisturizing doesn't keep up, the skin moisture can easily evaporate into the air, so moisturizing is the most important thing in our skincare.

Hyaluronic acid, also known as hyaluronic acid, is a substance contained in the human body itself, and the amount of content in the skin directly determines the strength of the skin's ability to lock in moisture.

It has good water retention performance, strong water absorption, can absorb water in the air to supplement the skin to achieve high moisturizing effect, and can form a breathable film on the surface of the skin to isolate the invasion of external harmful substances, and the small molecule part can penetrate into the dermis, accelerate blood circulation, improve metabolism, repair damaged cells, and promote nutrient absorption, which is a powerful hydrating ingredient.

 Hydrolyzed collagen, small molecule collagen

Collagen is known as "the bone in the bone, the skin in the skin, and the flesh in the flesh", which has a great effect on women, isn't collagen anti-aging? Yes, the existence of collagen makes the mesh fibers of the dermis more elastic and tough, and at the same time there is a key role - storing moisture, collagen is sufficient, skin moisture is not easy to lose, including skin damage repair, are inseparable from the contribution of collagen!

Collagen contains hydrophilic natural moisturizing factors, which have strong permeability to the skin, can combine with the cells on the skin through the stratum corneum, participate in and improve the metabolism of skin cells, and enhance the collagen activity in the skin.

Amino acids are also a substance that exists in the human body itself, it is a nutrient that cells need, can help cell energy metabolism and anti-inflammatory. Amino acids with small molecular structure are easily absorbed by the skin, and there are many functions of amino acids, which can be added to skin care products to repair damaged keratin and hydrate the skin. In addition, it also has an antioxidant effect, which can improve the breakage of the elastic mesh repair. It also has the effect of repairing and improving acne scars, and it can be used for sensitive skin to repair skin immunity, and it is a very powerful ingredient!

We often see amino acid cleansing products, and the above nutritional amino acid structure is different, it is added in the cleansing products of the active agent hydrophilic base, although the nutrition is different, but it is also relatively mild, sensitive skin can be used, there will be no tightness and irritation after use, it is recommended to use amino acid cleansing products for dry and sensitive skin.

At present, humectants are often divided into three categories according to the mechanism of action: occlusive humectants, hygroscopic humectants and biomimetic humectants.

Oils and waxes: mineral oil, paraffin, squalene, vegetable oil, animal oil (e.g. lanolin), silicone, etc.;

Fatty acids and esters: stearic acid, isopropyl isostearate, octyl stearate, etc.;

 Silicone oil: dimethicone oil, cyclopolysiloxane, etc.

 Most potent: glycerin, polyethylene glycol, etc.;

 Weaker: D-panthenol, sodium carboxymethylcellulose, sodium alginate, etc.;

 Weak: sodium pyrrolidone carboxylate, sorbitol, etc.

Maintain water classification: chondroitin sulfate, β-glucan and other polysaccharide humectants, etc.;

 Barrier-strengthening products: ceramides, squalene, phospholipids and cholesterol, etc.;

 Many brands will focus on a single ingredient,

 It will also combine various ingredients in one product.

 You can choose carefully according to the ingredients.
