Serum

Serum is a type of skin care product designed to deliver high concentrations of active ingredients deep into the skin. They are often more concentrated than regular creams and lotions, and can therefore help treat specific skin problems and improve the overall condition of the skin. Serums can contain ingredients such as hyaluronic acid, vitamin C, retinol and peptides that can help increase collagen production, reduce the appearance of fine lines and wrinkles, improve skin elasticity and protect against free radical damage. Serum is typically used after cleansing and before using a day or night cream, as it allows active ingredients to penetrate deep into the skin and work in a more effective way.
