Korean beauty trends have influenced the skincare world in more ways than we can count. From introducing us to sheet masks, essences and even ten-step routines, we love incorporating K-beauty practices into our skincare routines. Currently we’re obsessed with ampoules — serum-like products that are designed to address very specific skin concerns. Keep reading for a deep dive on ampoules, including what they are, how to use them and some of our favorites to try.What Are Ampoules?Ampoules contain high concentrations of specific ingredients that address a variety of skin concerns including dull skin, dryness, signs of aging, rough texture, discoloration, dark spots and more. Think of them as a serum, just with a higher potency. Though ampoules and serums are similar, ampoules often come in either plastic or glass vials that contain the optimal dosage for maximum efficacy. Plus, the single-dose packaging ampoules are very portable, making them a great product to travel with. Do I Need an Ampoule?If you’re searching for a way to address a skin concern with more potency than your current serum, ampoules are the way to go. They’re relatively easy to incorporate into your skincare routine — depending on your formula of choice, you can apply it before your serum. To apply, carefully break open the vial and smooth the entire pre-portioned amount onto your skin. Once it has absorbed into the skin, you can follow up with your serum and moisturizer. Looking to add an ampoule to your routine?
