What is Calcium ion?

Calcium ion (Ca²⁺) exerts an astringent action that tightens the skin. It is also said to help soothe flushing and inflammation after bathing.

Main Effects

  • Skin-tightening astringent actionCalcium ions bind with keratin proteins in the outer layer of the skin. This action creates a gentle tightening effect, which can leave the skin feeling firm and smooth after bathing.
  • Calming flushing sensationThese ions are believed to help reduce the feeling of being overly warm or flushed after a hot bath. This is attributed to their ability to gently suppress nerve excitement, leading to a more comfortable sensation.
  • Said to calm inflammation
