Typical antioxidants protect skin by neutralising and eliminating free radicals. However, they do have some limitations as they can also scavenge oxygen.

In contrast, Spin Trap is selective, only trapping harmful free radicals and not essential oxygen molecules.

Spin Trap (Phenyl t-Butylnitrone, or PBN for short) captures harmful free radicals before they can cause damage, converts them into useful oxygen, then transports them back to the respiratory system where they can go to work.
