The skin barrier

When your barrier breaks down, B5 builds it back.

Problem
Stressed skin barrier: cracked, dry surface losing moisture

A stressed barrier

Under daily stress the barrier cracks and lets moisture escape, leaving skin dry, red and sensitive.

With B5
Restored skin barrier: plump, hydrated, sealed layers

A restored barrier

10% Pro-Vitamin B5 floods skin with moisture and rebuilds the barrier, so it stays calm, hydrated and resilient.
