We know Korean beauty for being on the cutting edge of the latest skincare trends. Anyone looking into how to take care of their skin has run into the k-beauty 10 step routine. One step calls for ampoules to be used. But what exactly are they?

Ampoules are like serums in theory, but much more potent. These super hydrating products have a high concentration of an active ingredient and tend to be more slippery than a serum. The texture and formula allow you only to use one or two drops. Massage directly onto your face or even before putting on a sheet mask to allow for it to absorb.

Here are some of the best-selling ampoules to try:
