While every step of your skin-care routine is important — no question there — they’re not all created equal. Some are more powerful than others. Face serum is one of those non-negotiable steps, in part because it can do so much for your skin.
These super-concentrated formulas target your biggest care concerns, complementing everything else you do for your skin. Yes, double-cleansing and moisturizing can do a lot in their own right, but add in face serum and you’re going to do great things for your skin — hydrate, brighten, repair, or all of the above. Here, we’re getting into exactly what is serum, along with why you need one.
A serum is a targeted treatment in your skin-care routine. It has a high concentration of active ingredients to address a particular concern, be it dehydration or dull skin. Since it addresses specific issues, you can customize the serum you use or even cocktail a few, depending on what’s happening with your skin. Serums feel lightweight and typically absorb quickly.
Serums are not to be confused with ampoules, which are also targeted treatments considered a mainstay in K-beauty. In some cases, they’re used for a limited time (think two to four weeks) in place of serum, while others are layered on before your serum step.
