Serums are usually formulated with a specific skin concern or condition in mind, and are designed to be used in conjunction with other skin care products to optimize results. Some common uses for serums include improving the appearance of
discoloration,  wrinkles,  acne,  excess oil,  redness, or rough surface texture.  Vitamin C serums  are an important and effective way to provide the skin with antioxidants to help prevent environmental damage, while  hyaluronic acid serums  are used to enhance skin hydration in all skin types. There are also serums that combine multiple ingredients to provide improvement for specific combinations of concerns (such as acne and visible signs of aging) as well as comprehensive anti-aging benefits. Serums can also be formulated for specific areas of the face, such as around the eyes or for the lips.
