Formulation Issues with High Concentration AHA/BHA/Vitamin C Cream/Serum

Based on the staff's response, here is a summary of the issues with your formula and the recommended adjustments:

• Formula Incompatibility: Your current formula is not compatible.
• Glycolic Acid (AHA) 100% Powder: This ingredient makes it difficult to emulsify and create a cream texture. The staff recommends replacing your current emulsifier (Light Cream Maker) with acid-tolerant alternatives like Pro Polymer (1.5-2.5%), Satin Cream Maker (1.5-2.5%), or Butter Cream Maker (4-5%).
• Salicylic Acid (BHA): The standard Salicylic Acid will not dissolve in your formula. Please switch to Salicylic Acid EZ, which is water-soluble.
• Stickiness and Irritation: The high concentration of ingredients is the cause of the stickiness and significantly increases the risk of skin irritation. The staff strongly advises against using these concentrations on facial skin.
• Recommended Concentrations: The staff recommends the following maximum concentrations for key ingredients:
  • Glycolic Acid (AHA) 100% Powder: max 5%
  • Salicylic Acid EZ: max 5%
  • Vitamin C (L-ascorbic acid) (Ultra-Fine): max 10%
  • Other ingredients (Glutathione, Natural Betaine, WaterLock™, Disodium EDTA) can be kept at your original percentages.
• Reducing Stickiness: Stickiness is a natural characteristic of glycolic acid. You can reduce it by using a limited concentration or by adding emollients to improve the skin feel.
