Products used to increase the water content of the skin's surface

Explanation:

Humectants are products that increase the skin's water content by drawing moisture from the air or the dermis into the epidermis. They are a key ingredient in moisturizers along with occlusives.

Moisturizers often contain humectants because they help modify the rate of water loss by absorbing water. Humectants have the ability to draw water from the air in high humidity conditions or more commonly, they draw water from the dermis into the epidermis. This process helps in keeping the skin hydrated and moisturized.

Humectants are essential components in moisturizing creams and lotions. They work best when combined with occlusives, which form a coating on the surface of the skin to prevent moisture from escaping. Moisturizers containing both humectants and occlusives provide long-lasting hydration and keep the skin looking healthy and supple.

The main ingredients of creams and lotions designed to protect, moisturize, lubricate the skin, and alleviate itchiness and inflammation include humectants, occlusives, water, oil, emulsifiers, and thickening agents. These products play a vital role in maintaining the skin's water content and overall health.
