Active ingredients are powerful, but they’re only effective when used at the right pH. That’s why we’ve organized our serums and oils by pH range and potency:

• Start gentle: Use milder pH formulas as your skin adapts.
• Build tolerance: Gradually introduce stronger actives, guided by your skin’s response.
• Protect your barrier: Our method lowers irritation and shields your skin from damage.
  

Note: Oil-based products don’t carry a pH (they’re water-free). They’re universally compatible — even for oily or sensitive skin.
