How to use  

1. Use daily in your morning and evening skincare routines.
2. After cleansing and prepping your skin with a toner, dispense 2-3 drops of the serum directly onto your face.
3. Smooth evenly over your skin, massaging extra product into specific areas of concern (like stubborn dark spots or acne scars).
4. Gently pat with your fingertips until fully absorbed.
5. Crucial Step: Because this serum actively fades pigmentation, you must apply a generous layer of broad-spectrum sunscreen as the final step of your morning routine to protect your newly brightened skin and prevent further UV damage.

What it is & why it works  

What it is: An intensive, clinical-strength brightening serum formulated to aggressively target and fade stubborn dark spots, melasma, and red or brown post-acne scarring.
Why it works: Uneven skin tone requires a multi-angled attack. Instead of relying on a single active, this powerhouse serum combines the industry's most effective brightening agents. It features a heavy dose of Glutathione (the master antioxidant) and Pure Vitamin C to neutralize the free radicals causing discoloration. It then layers in 5% Niacinamide, Alpha-Arbutin, and Tranexamic Acid to halt melanin production at every stage. This synergistic formula literally breaks down existing pigmentation while preventing new spots from forming, all while keeping the skin deeply hydrated and shielded from irritation.

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.
