Why Your Skin Turns Red
The pH Imbalance
Healthy
pH < 5.0
Sensitive
pH < 6.0
High pH = Weakened Barrier
Sensitive skin tends to have a higher pH level. When this balance is disrupted, your moisture barrier weakens, making external stimuli trigger instant redness.
- Barrier weakens & inflammation triggers
- Moisture loss increases drastically
- Visible redness and irritation follows
