Korean serums are lightweight, concentrated formulas designed to target specific skin concerns. Choose niacinamide for uneven-looking tone, hyaluronic acid for dehydration, retinol or peptides for signs of ageing, and centella for soothing sensitive or irritated skin. Many formulas combine several complementary ingredients, allowing you to address more than one concern in a single step.

Apply serum after toner and essence, then follow with moisturiser. Introduce one active formula at a time and use it consistently, as visible results can take several weeks depending on the ingredient and your skin concern.
