Niacinamide
“Stops your skin leaking water by the hour.”
What it actually does
Helps skin build the lipids that keep water in, so it loses less moisture through the day — and helps with the look of pores and uneven tone. One of the most studied ingredients in skincare, which makes it easy to justify honestly. Two doses, two jobs: 2% in HydraShield, where the work is gentle daily barrier support; 4% in the Toner Serum Hybrid, where it's doing heavier lifting on pores and tone for oily-combination skin.
