Designing a simple AM–PM winter routine around your serum
Evening: keep the base same, add strong actives thoughtfully At night, repeat gentle cleansing and your hydrating serum. If you use vitamin C, exfoliating acids or retinoids, either apply your barrier serum first and let it absorb, or follow your dermatologist’s specific instructions. If your skin stings with actives, try “sandwiching”: moisturizer, then active, then a thin layer of moisturizer again. On nights you use retinoids, many people skip strong acids and stick to hydration and barrier support only.
