Maison's Note · Why We Curated
Niacinamide at 20%, a concentration few formulations sustain without irritation. We chose it as the clinical tier of the Niacin protocol, for skin that has outgrown gentler brightening.
Description
A high-strength brightening ampoule with 20% Niacinamide and a stable vitamin C derivative for improved skin tone, clarity, and antioxidant defense.
Beta-glucan, panthenol, and hyaluronic acid help keep the skin comfortable and hydrated. Best introduced gradually. Avoid use on freshly resurfaced skin.
How to Use
Take an appropriate amount with a pipette, drop it on the forehead and both cheeks, and let it absorb by gentle patting.
Clinical Efficacy

- Niacinamide 20%: intensive brightening and tone
- 3-O-Ethyl Ascorbic Acid (Vitamin C): radiance and antioxidant protection
- Glutathione: antioxidant, limits pigment formation
