What's inside ·

Vitamin C, the repair molecule

Niacinamide works at the junction between melanocytes and keratinocytes, intercepting melanin transfer before pigment reaches the visible surface. It simultaneously boosts ceramide synthesis to strengthen the lipid barrier, which is why consistent use addresses both discoloration and dehydration. In this ampoule, Niacinamide targets fine lines and wrinkles, delivering evens out skin tone for a clearer, more uniform complexion with consistent use.
Niacinamide
intercepts melanin transfer to fade spots and refine pore texture from within
Vitamin C
neutralizes free radicals and inhibits melanin production for brighter, more protected skin
Tranexamic Acid
blocks melanin transfer to fade stubborn dark spots that resist other treatments

Lightweight, concentrated Glutathione tone reset

GLUTATHIONE TONING BOOSTING AMPOULE (30 ml/1.01 fl oz) contains 200,000 ppm of Glutathione Toning Complex, alpha-bisabolol, niacinamide and vitamins to improve your overall skin tone and complexion.

GLUTATHIONE, the main active ingredient found in this ampoule, is an antioxidant that inhibits the production of melanin. Excess melanin production can lead to hyperpigmentation and uneven skin tone. By reducing melanin production, glutathione can help combat dull uneven skin by evening out skin tone and improve overall skin appearance.

SKIN PROTECTION - In addition to glutathione, 10,000 ppm of tranexamic acid, 100 ppm of melatonin, vitamin C, and milk exosomes have been added to this product to help protect your skin from free radical damage, which can accelerate the visual aging process.

HOW TO USE - Apply an appropriate amount of ampoule to your skin after cleansing and toning your face, gently pat in for better absorption. Pairing this product with Derma Pulse Booster Multi-Shot, our pro-level microcurrent beauty device, will bring out maximum results.

Ingredients

Glutathione, niacinamide, tranexamic-acid support, and vitamin care work together to help skin look brighter and more even.

This ampoule is clearly built around discoloration and radiance, which is why its ingredient stack combines several familiar tone-care pathways. Glutathione is positioned as the headline antioxidant brightener, supporting a clearer-looking complexion and a more even overall tone. Niacinamide and tranexamic-acid support strengthen that effect by helping reduce the look of lingering pigmentation while also supporting barrier function and surface smoothness. Vitamin support keeps the complexion looking fresher, while bisabolol adds a soothing angle that helps the formula stay comfortable for routine use. The lightweight ampoule format is useful because tone-care works best with consistency, and products that feel too heavy are harder to use regularly. Overall, the formula works as a concentrated daily brightening step: improve visible dullness, target uneven tone, and leave the skin looking more luminous and refined without sacrificing hydration.
