Maison's Note · Why We Curated
5,000ppm of pure retinol in an airless pump, a delivery system as considered as the concentration. We chose it as our firmness reference for skin ready to commit.
Description
A high-strength serum with 5,000 ppm of pure retinol (0.5%) that firms the skin and smooths the look of wrinkles. It is designed for resilient skin ready for a potent active.
Retinol drives visible firmness and renewal, buffered by Ferulic Acid and soothing botanicals for tolerability. Introduce gradually and reserve for skin with a fully recovered barrier.
How to Use
After toner, apply a suitable amount to the areas of concern and absorb gently along the skin texture. Use in the evening. When used during the day, always follow with a broad-spectrum sunscreen that blocks UVA and UVB.
