The Benefits Of Hyaluronic Acid For Skin: Excellent Moisturizer

You often see hyaluronic acid when you look at the ingredient list of skin care products, but you are very unfamiliar with it because you don’t know what it does.

What Is Hyaluronic Acid?

In 1934, Meyer, a professor of ophthalmology at Columbia University in the United States, discovered hyaluronic acid in the vitreous of a bull’s eye for the first time, so he named it hyaluronic acid.

The molecular structure of hyaluronic acid is a combination of two types of glucose connected to each other. The molecular structure of hyaluronic acid is very similar to polysaccharides, so hyaluronic acid also has a strong moisturizing ability.

Hyaluronic acid is present in many parts of our body, including the eyes, gums, joints, and skin. Therefore, hyaluronic acid was first used as a pharmaceutical ingredient, such as eye drops, joint lubricants, and so on.

Why is hyaluronic acid so well-known?

One reason is that it is a natural ingredient that exists inside the skin and is safer to use.

Another reason is that the publicity is done well. One thing can make money, and the business will spare no effort to publicize it.

Hyaluronic acid in the skin is located in the epidermis and dermis. It has high viscosity, silky smoothness, and super water absorption capacity. It is filled between skin cells and plays an irreplaceable role in the connection and communication between cells.

Because of its existence, the skin can maintain sufficient moisture, make the skin soft and smooth, remove wrinkles, increase elasticity, anti-aging, and promote wound healing.

The facial masks that all girls often use contain a lot of hyaluronic acids, so the skin after using the mask is very soft and elastic.

Types Of Hyaluronic Acid

Hyaluronic acid is not a single simple ingredient, it can be divided into many types, and the functions of different hyaluronic acids are different.

Hyaluronate

Some products containing hyaluronic acid will be in the form of salt, such as sodium hyaluronate, potassium hyaluronate, and so on.

Sodium hyaluronate has stronger stability and penetration ability. The molecular weight of sodium hyaluronate is smaller, which means that when hyaluronic acid can only act on the surface of the skin, sodium hyaluronate can penetrate deeper into the skin more effectively.

But objectively speaking, although sodium hyaluronate can penetrate into the skin more easily, it does not necessarily mean that its skin care effect is better than hyaluronic acid.

Molecular weight

The molecular weight of hyaluronic acid is large or small and can be divided into three types according to the molecular weight.

Macromolecular hyaluronic acid (molecular weight above 1 million): Very viscous, forming a layer of breathable film on the skin, locking in moisture, high viscosity will give the skin a sense of firmness.

Medium-molecular-weight and low-molecular-weight hyaluronic acid (molecular weight of 100,000 to 1 million DA): The permeability is relatively better, so the duration of moisturizing is longer than that of large molecules.

Hydrolyzed hyaluronic acid (molecular weight of several thousand to 10 thousand DA): Nanometer size, it is very easy to penetrate the skin, and can also promote the absorption of other ingredients, and has the effect of fast moisturizing and repairing skin damage.

TIP: The molecular weight of hyaluronic acid cannot be seen from the product ingredient list. No matter how large the molecular weight is, it is called hyaluronic acid. So when buying skin care products, look for trusted brands.

The Role Of Hyaluronic Acid

After 1980, hyaluronic acid was used in cosmetics. At that time, hyaluronic acid used in skin care products was extracted from cockscomb, so it was expensive.

According to different ways of using hyaluronic acid, it can be divided into basic skin care and aesthetic medicine.

Basic skin care

The biggest role of hyaluronic acid in skin care products is moisturizing.

Hyaluronic acid is the substance with the best moisturizing properties in nature found so far and is known as an ideal natural moisturizing factor. Experiments have found that it can absorb water 1,000 times its weight.

Imagine that hyaluronic acid is a sponge that can not only lock the moisture inside the skin but also absorb the external moisture properly.

Hyaluronic acid is different from other humectants, such as glycerin. It is less affected by environmental humidity and is suitable for various skin types and climatic conditions.

Besides, hyaluronic acid also has anti-oxidation, scavenging free radicals, reducing the damage of ultraviolet rays to the skin, promoting the proliferation and differentiation of epidermal cells, repairing and protecting the skin, increasing lubrication and thickening.

Aesthetic medicine

Hyaluronic acid used in aesthetic medicine mainly has the following purposes:

1. Anti-aging

We can inject hyaluronic acid into the skin to remove static wrinkles on the skin, such as brow lines, crow’s feet, lower eyelid lines, mouth lines, necklines, etc.

2. Facial filling

With age, facial collagen will gradually be lost. To solve the problem of facial depression caused by the lack of collagen, hyaluronic acid has gradually replaced silica gel and has become the first choice for facial filling. Cheeks, temples, and tear grooves can be filled with hyaluronic acid to make the face look fuller.

Hyaluronic acid can also be used for rhinoplasty, lip enhancement, lower bar filling, forehead filling, brow filling, etc. The molecular weight of hyaluronic acid used to shape the facial shape is relatively large, and the depth of injection must be at least to the deep layer of the dermis.

3. Mesotherapy

Simply put, it is to inject small molecules of hyaluronic acid into the skin evenly and in small amounts with an injection device. This kind of injection is relatively shallow and can play a role in moisturizing, wrinkle removal, skin lightening, shrink pores, and improving skin condition.

Conclusion

Hyaluronic acid is the best moisturizing ingredient in skin care products. Different types of hyaluronic acid have different effects on the skin.

It can also be used in medical cosmetology to make you look more charming.
