Kosteaja

Kosteaja is a Finnish term that translates to "moisturizer" or "moisturizing agent" in English. It refers to a substance or product designed to hydrate and soften the skin. Kosteaja is commonly used in the context of skincare and cosmetics. These products typically contain ingredients that help to attract and retain moisture in the skin, such as humectants (like glycerin or hyaluronic acid) and emollients (like various oils and butters). They can also contain occlusive agents that form a barrier on the skin to prevent water loss. Kosteaja products are available in a wide range of formulations, including lotions, creams, serums, and balms, catering to different skin types and concerns. Their primary function is to combat dryness, improve skin texture, and maintain the skin's protective barrier. In a broader sense, the term can also apply to ingredients within a product that contribute to its moisturizing properties.
