Serums
Serums are where a routine gets specific. These are single-purpose formulas at meaningful concentrations — stabilised vitamin C for tone and clarity, multi-weight hyaluronic acid for cushion and bounce, niacinamide with zinc for congestion and redness — so you can add one concern at a time instead of guessing at a blend. Apply to damp skin, give each a minute to settle, and layer lightest to heaviest. Introduce one new serum a fortnight; skin tells you more when only one thing has changed.
