Step 4: Add an Ampoule
If you're secretly a beauty chemist and like to play mix and match with your products, Kim advises merging an ampoule with your night cream at night and an SPF cream during the day. This should be applied after you exfoliate.
For those who don't know, an ampoule is a serum that contains a highly concentrated amount of an active ingredient. These active ingredients target one specific skin concern (i.e. dryness, breakouts) and are meant to be used when your skin needs an extra boost. They typically come inside small bottles with a dropper applicator.
Since they're still pretty new to the US market, you'll find most of them at online K-beauty retailers. One of our favorites is Tony Moly's Intense Care Snail Ampoule ($29); it contains 92 percent snail slime, which provides extreme hydration to dull skin.
