pH Level
Slightly acidic — close to skin's natural pH (4.5–5.5). Gentle and generally well tolerated.
Dermatologist Note
The addition of vitamin B5 (panthenol) enhances the film-forming and water-binding capacity of hyaluronic acid. Always apply to damp skin and seal with a moisturizer — hyaluronic acid without an occlusive on top can increase TEWL in low-humidity environments.
