What it is & why it works  

What it is: A highly concentrated nighttime anti-aging treatment powered by Retinal (Retinaldehyde), which works up to 11 times faster than traditional retinol.
Why it works: Retinal accelerates cellular turnover and boosts collagen production, directly targeting fine lines, wrinkles, and loss of elasticity. Formulated without alcohol, this booster shot minimizes the irritation and dryness typically associated with Vitamin A, using supporting ingredients like Ceramides and Peptides to protect the skin barrier while delivering maximum firming results.

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.
