LON.G Intensive Vit C 5-Week Ampoule Serum

Fresh Vitamin C, week by week.

LON.G Intensive Vit C Ampoule Serum is a five-week intensive brightening program designed to keep Vitamin C fresh until the moment of use.

Its innovative dual system keeps the highly concentrated Vitamin C capsule separate from the serum. When activated, the capsule and serum are freshly mixed together for each weekly skincare routine.

Why It’s Different

• 5-Week Intensive Program — Five individual ampoules, with one bottle used each week
• Fresh-Mixing Vitamin C System — Vitamin C capsule and serum remain separated until activation
• Double Core Shell Stabilization Technology — Helps protect Vitamin C from oxidation before use
• Double-Layered Container — Designed to mix the Vitamin C capsule and serum just before application
• Glutathione Serum — Paired with concentrated Vitamin C for brightening care
• MFDS Certified Functional Cosmetic — Certified in Korea for brightening and wrinkle improvement
• Clinically Tested — Evaluated for skin elasticity, brightness, and the appearance of wrinkles around the eyes

How to Use

1. Open the lid and press the pump to release the Vitamin C capsule into the serum.
2. Shake thoroughly until the ampoule turns yellow and the capsule is fully mixed with the serum.
3. Pump 2–3 times and apply evenly over the face.
4. Use each activated ampoule within 7 days.
5. Continue with one ampoule per week for the full five-week program.
