Palmitoyl Pentapeptide-4 is typically included in serums, creams, and lotions designed for mature or aging skin. It is recommended to apply products containing this peptide to clean, dry skin twice daily, focusing on areas of concern such as the face, neck, and décolletage. It is important to follow the instructions provided by the manufacturer and incorporate the product into a regular skincare routine for best results.

1. Definition Hyaluronic Acid:

Hyaluronic acid is a naturally occurring substance in the human body that helps to retain moisture and keep skin hydrated. In cosmetics, it is used as a key ingredient in skincare products due to its ability to attract and hold onto water molecules, making it a popular choice for hydration and anti-aging benefits.

2. Use:

Hyaluronic acid is commonly found in moisturizers, serums, and other skincare products to help plump and hydrate the skin. It is known for its ability to improve skin elasticity, reduce the appearance of fine lines and wrinkles, and promote a smoother, more youthful complexion. Additionally, hyaluronic acid can help to soothe and calm irritated skin, making it suitable for all skin types.

3. Usage Hyaluronic Acid:

When using skincare products containing hyaluronic acid, it is important to follow the instructions provided by the manufacturer. Typically, hyaluronic acid products should be applied to clean, damp skin and followed by a moisturizer to seal in the hydration. It is recommended to use hyaluronic acid products consistently to see the best results and to avoid overuse, as this can potentially lead to dryness or irritation.

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.

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.
