Description

The Lon.G Intensive Vit C Ampoule Serum comes as a single ampoule, ideal if you want to try the formula before committing to the full five-week set. One ampoule lasts 7 days.

What makes it different is the dual-layer container. A capsule of high-concentration vitamin C stays separated from the glutathione serum until you open it, so the two mix only at the moment of use. This keeps the vitamin C fresh and limits oxidation over the week you use it.

Key ingredients

  • Vitamin C – An antioxidant that helps the skin look brighter and more even.
  • Glutathione – Often called "the mother of all antioxidants," added to the serum layer for a clean, radiant appearance without irritation.
  • Niacinamide (vitamin B3) – Helps even out the look of skin tone and supports the skin barrier; useful for the appearance of dark spots and uneven areas.
  • Adenosine – Helps skin look smoother and firmer. Stable in light and heat, so it works for both daytime and evening routines.
  • Broussonetia Kazinoki Root Extract – Helps refine the look of skin texture.

What it helps with

  • A brighter, more even-looking complexion
  • The appearance of a smoother, firmer surface
  • A more radiant, refreshed look

Who is it for?

It suits anyone who wants a brighter, more even appearance and a fresh dose of vitamin C in their routine. Because adenosine stays stable in light and heat, the ampoule fits both morning and evening use.

How do you use the ampoule?

Open the dual-layer container to mix the vitamin C capsule with the glutathione serum, then apply across the face. Vitamin C is most active right after mixing, so use freshly opened. One ampoule is designed to last about 7 days; apply after cleansing and toning, and follow with moisturiser. For daytime use, finish with sunscreen.

Clinical testing

The serum was instrumentally assessed with 20 adult women between 13.08.2019 and 11.09.2019 using Antera 3D analysis. No significant skin irritation or abnormalities were observed during the testing period. Measured before use versus after 4 weeks:

  • Skin elasticity: 8.05% → 16.49%
  • Skin brightness: 0.06% → 1.44%
  • Appearance of fine lines under the eyes: average 27.82% improvement

How to use

Open the cap and press the pump at the top of the container firmly until it clicks. Hold the sprayer down for 5-10 seconds to release the powdered product. Shake the container vigorously to mix the capsule and serum until the ampoule turns yellow.
Pump 2-3 times and apply evenly across your face. Wait 10-15 minutes before applying the next product.

We recommend using the serum in the evening due to the light-sensitivity of the formula.
If using in the morning, do not forget to protect your skin with sunscreen.

One bottle per week – store in the refrigerator after mixing, use within 7 days.
