Sodium Hyaluronate Crosspolymer

Function: Skin Conditioning, Humectant

1. Definition Sodium Hyaluronate Crosspolymer:

Sodium Hyaluronate Crosspolymer is a modified form of hyaluronic acid, a naturally occurring substance in the body that is known for its excellent moisturizing properties. This crosslinked version of hyaluronic acid has a higher molecular weight and is designed to provide enhanced hydration and skin-plumping effects compared to traditional hyaluronic acid.

2. Use:

Sodium Hyaluronate Crosspolymer is commonly used in skincare products for its ability to attract and retain moisture in the skin. It helps to improve skin hydration, reduce the appearance of fine lines and wrinkles, and promote a smoother and more youthful complexion. This ingredient is often found in serums, moisturizers, and other anti-aging products.

3. Usage Sodium Hyaluronate Crosspolymer:

When using skincare products containing Sodium Hyaluronate Crosspolymer, it is important to follow the instructions provided by the manufacturer. Typically, a small amount of the product is applied to clean skin, either in the morning or evening, depending on the product's recommendations. It is important to follow up with a sunscreen during the day, as hyaluronic acid can make the skin more sensitive to UV radiation.

Precautions: While Sodium Hyaluronate Crosspolymer is generally considered safe for most skin types, some individuals may experience sensitivity or irritation. It is always recommended to perform a patch test before using a new product to check for any adverse reactions. If irritation occurs, discontinue use and consult a dermatologist.

Hydrolyzed Sodium Hyaluronate

Function: Skin Conditioning

1. Definition Hydrolyzed Sodium Hyaluronate:

Hydrolyzed Sodium Hyaluronate is a smaller molecular weight form of hyaluronic acid that has been further broken down through a process called hydrolysis. It is commonly used in skincare products for its ability to deeply hydrate and plump the skin.

2. Use:

Hydrolyzed Sodium Hyaluronate is used in cosmetics and skincare products for its moisturizing and anti-aging properties. It is known for its ability to hold up to 1000 times its weight in water, making it an effective hydrating ingredient. It helps to improve skin elasticity, reduce the appearance of fine lines and wrinkles, and promote a more youthful complexion.

3. Usage Hydrolyzed Sodium Hyaluronate:

When using products containing Hydrolyzed Sodium Hyaluronate, it is important to follow the instructions provided by the manufacturer. Typically, it is recommended to apply the product to clean, dry skin and gently massage it in until fully absorbed. It can be used both morning and night as part of a skincare routine. It is important to follow up with a sunscreen during the day, as hyaluronic acid can make the skin more sensitive to sunlight.

Potassium Hyaluronate

Function: Skin Conditioning

1. Definition Potassium Hyaluronate:

Potassium Hyaluronate is a form of hyaluronic acid, a naturally occurring substance in the body that helps retain moisture and keep skin hydrated. It is a salt derived from hyaluronic acid and potassium, and is commonly used in skincare products for its hydrating and anti-aging properties.

2. Use:

Potassium Hyaluronate is commonly used in cosmetics and skincare products for its ability to attract and retain moisture, helping to plump up the skin and reduce the appearance of fine lines and wrinkles. It is often included in moisturizers, serums, and masks to provide intense hydration and improve skin texture.

3. Usage Potassium Hyaluronate:

When using products containing Potassium Hyaluronate, it is important to follow the instructions provided by the manufacturer. It is typically applied to clean, dry skin and can be used both in the morning and at night. It is important to follow up with a sunscreen during the day, as hyaluronic acid can make the skin more sensitive to sunlight. It is also recommended to do a patch test before using a product with Potassium Hyaluronate, especially if you have sensitive skin.

Dextrin

Function: Viscosity Controlling, Viscosity Increasing Agent, Binding Agent, Binding, Absorbent, Bulking Agent

1. Definition Dextrin:

Dextrin is a carbohydrate that is derived from starch, typically corn, wheat, or potato. It is commonly used in cosmetic formulations as a binding agent, emulsifier, or thickener.

2. Use:

Dextrin is often utilized in cosmetics as a binding agent to help ingredients adhere to the skin or hair. It can also be found in hair products to provide hold and structure. Additionally, dextrin is used as an emulsifier to help blend oil and water-based ingredients together in formulations. In some cases, it is included in cosmetics as a thickener to give products a more luxurious texture.

3. Usage Dextrin:

When using cosmetics containing dextrin, it is important to follow the manufacturer's instructions and guidelines. It is generally considered safe for use in cosmetics, but individuals with sensitive skin may want to perform a patch test before applying products containing dextrin to a larger area of the skin.
