Korean ampoules are focused skincare treatments designed to deliver hydrating, soothing or revitalising ingredients in a lightweight formula. They are often more concentrated than traditional serums, but this varies by product and brand. Popular ampoule ingredients include centella, peptides, PDRN, propolis and hyaluronic acid.

Apply your ampoule after toner and essence, then follow with serum or moisturiser. You can also use it in place of a serum to keep your routine simple. Always layer products from the lightest to the richest texture and follow the individual product instructions.
