How do I use & layer this?  

AM: Cleanse (gentle wake-up wash) → Tone/Mist (quick hydrating sip) → Treat (essence/serum/ampoule) → Eye cream (tap gently around the eye area) → Moisturize (seal in hydration) → SPF (don’t skip!).
PM: Double cleanse (oil/balm to remove makeup & SPF → water-based cleanser) → Tone/Mist → Masks or Devices (optional; 2–3 times a week) → Treat (essence/serum/ampoule) → Eye cream → Moisturize.

New to K-Beauty? Follow the “thin → thick” rule: start with watery (toner/essence) → then lighter serums → then cream → finish with sunscreen in the morning.
Caution: Avoid layering strong acids (AHA/BHA/PHA/peeling solutions) with retinoids on the same night, and introduce actives slowly if you have sensitive skin.
