  • 20% niacinamide. One of the highest concentrations available on the market. Targets visible pore size and uneven tone.
  • Arbutin and zinc PCA. A brightening and sebum-balancing pair that works alongside the niacinamide.
  • Hyaluronic acid stack. Multiple forms of HA inside to soften the dry feel that high-dose niacinamide can leave.
  • Botanical comfort. Pine leaf, oenothera, and licorice extracts support reactive skin.
  • Travel-friendly 20 ml. Concentrated and focused. Use sparingly.

How to use

Dispense 2 to 3 drops onto the palm and pat across the face until absorbed. Always wear sunscreen the next day.
