Serums
If you think of your nightly skin care routine as a three course meal, serum is kind of like the main course. After kicking things off with an appetiser (aka cleansing your face), and before treating yourself to dessert (aka a nourishing moisturiser), you fill up on all the important nutrients (aka serum).
Much like a main course, serums can contain a range of useful nutrients — for your skin.
Serums are skin care products that are designed to deliver high concentrations of specific active ingredients to the skin. There are many different types of serums on the market that perform different jobs, ranging from hydration to skin brightening.
