Whether it's spring, summer, autumn, or winter, moisturizing is important for every woman. OEM formulas for moisturizing cosmetics generally contain vitamins A, B1, B2, B6, and C, or are made from plant extracts. Different moisturizing products have different levels of hydration. Just how important are moisturizing products in cosmetics for a woman?

What is moisturizing?

A must-learn lesson for women—moisturizing.

Let's start with the physiological functions of the skin. The skin consists of the epidermis, dermis, and subcutaneous fat. The outermost layer of the epidermis is the stratum corneum. Due to the stratum corneum's water absorption and barrier functions, as well as the natural moisturizing factors it contains, such as amino acids, lactates, and sugars, the stratum corneum maintains a certain water content, keeping the skin hydrated. The appearance of the skin is related to the water content of the stratum corneum. Normal skin's stratum corneum typically contains 10%-30% water to maintain the skin's softness and elasticity. However, as we age, the moisture content of the stratum corneum gradually decreases. When the moisture content of the stratum corneum falls below 10%, the skin becomes dry, tight, rough, and flaky.

What is the function of moisturizing?

Regardless of the type of cosmetics you use or the effects you achieve, moisturizing is the first and most important step for women. Moisturizing allows the skin to better absorb nutrients. It promotes skin metabolism and nutrient absorption. Therefore, if you moisturize well, the effects of other cosmetics will be more pronounced. The processing of moisturizing cosmetics aims to enhance the positive interaction between the skin and hydrating products.

How are moisturizing cosmetics processed?

Moisturizing cosmetics OEM contain moisturizing ingredients that maintain a certain level of moisture in the stratum corneum to restore the skin's radiance and elasticity. Based on their characteristics, moisturizing cosmetics mainly fall into two categories: one uses water-retaining substances that strongly bind with moisture on the skin surface to moisturize the stratum corneum, called humectants; the other uses water-insoluble substances to form a lubricating film on the skin surface, acting as a sealant to prevent moisture loss, thus maintaining a certain level of moisture in the stratum corneum, called emollients or conditioning agents. When choosing moisturizing cosmetics, it's essential to consider your individual skin type and needs, as different skin types require different moisturizing products.
