5 Science-Backed Tips for Choosing Vitamin C Products
- Optimal Concentration Range
- Stick to 10-15% L-Ascorbic Acid
- Higher percentages ≠ better results (often leads to more irritation)
- The Power Trio Formula
- Look for: L-Ascorbic Acid + Vitamin E + Ferulic Acid
- This combination maximizes stability and potency
- Packaging Intelligence
- Avoid clear bottles (oxidation accelerator)
- Seek dark glass or airless pump systems
- pH Considerations
- Effective range: pH 3.5 or lower
- Be wary of products marketed as “gentle” with neutral pH
- Visual Quality Assessment
- Acceptable: Slight yellow tint
- Red flag: Dark orange or brown coloration (indicates oxidation)
