Oil-free moisturizers are skincare products designed to hydrate the skin without using oils. They are ideal for people with oily or acne-prone skin, as they provide moisture without adding extra shine or clogging pores. These moisturizers often contain water-based ingredients and humectants like glycerin or hyaluronic acid, which help draw moisture into the skin. Using an oil-free moisturizer can help maintain a balanced complexion while keeping the skin feeling fresh and light. They are also suitable for all skin types, especially during hot and humid weather when heavier creams might feel uncomfortable. Look for labels that specify "oil-free" to ensure you're choosing the right product for your needs.
