Commonly formulated into all skincare formulations, especially AHA/BHA exfoliants and vitamin C.
Sodium Bicarbonate
Sodium Bicarbonate functions primarily as a ph adjuster. Its main purpose is ensuring formula matches the skin's natural acidic mantle (pH 4.5-5.5), which contributes to optimizing active ingredient efficacy while minimizing skin irritation. Commonly formulated into all skincare formulations, especially AHA/BHA exfoliants and vitamin C.
When to Choose Citric Acid or Sodium Bicarbonate
Choose Citric Acid for ensuring formula matches the skin's natural acidic mantle (pH 4.5-5.5). Effective in acid exfoliants, vitamin C serums, cleansers, and balancing toners.
Choose Sodium Bicarbonate for ensuring formula matches the skin's natural acidic mantle (pH 4.5-5.5). Works well in acid exfoliants, vitamin C serums, cleansers, and balancing toners.
Citric Acid & Sodium Bicarbonate: Skin Type Considerations
Citric Acid suits all skin types, crucial for maintaining a healthy acid mantle, while Sodium Bicarbonate works better for all skin types, crucial for maintaining a healthy acid mantle. Performance varies with concentration, product type, and other active ingredients.
