Skin oils and serums
Facial vegetable oils are an absolutely great all-purpose beauty product that you don't just have to use on your face. Most of the quality single-grade oils can be used for example unmask, use them as an alternative to a face cream (on properly moisturized skin, of course), or they can also replace an oil serum. The oils can also be used as a nutrition for frayed hair ends, nutrition for stressed nail cuticles, etc.
Facial serums are concentrated products designed for care for your skin. They are designed to provide a high concentration of active ingredients that can target various skin problems. Facial serums are usually applied before moisturiser and have a light, fast-absorbing consistency.
