Serum Formulation Issues: Stickiness and White Residue

Regarding your serum formulation for acne and melasma that feels sticky and produces white foam:

The staff has reviewed your formula and provided recommendations to address these issues.

Problem Diagnosis:

• Stickiness: The stickiness is likely caused by the Hyaluronic Acid (Standard Molecule).
• White Foam/Residue: The white foam or residue is due to the incompatibility between Methylsulfonylmethane (Pure MSM™) and Salicylic Acid.

Recommended Adjustments:
To resolve the stickiness and white residue, the staff recommends removing the following ingredients from your formula:

• Hyaluronic Acid (Standard Molecule) 0.5%
• Methylsulfonylmethane (Pure MSM™) 4%

Adjusted Formula (based on staff recommendations):

• 1,2-Hexanediol: 3%
• Hyaluronic Acid (Nano Molecule): 0.5%
• Distilled Water: 70%
• Tranexamic Acid (Trans-White™): 3%
• Vitamin B6 (Pyridoxine Hydrochloride): 3%
• Safe-B3™ (Vitamin B3, Niacinamide): 5%
• Licorice Extract (Licochalcone A): 1%
• GlucoBright™ (Acetyl glucosamine): 4%
• Zinc PCA: 1%
• Salicylic Acid EZ™: 5%

This adjusted formula is expected to be less sticky and should not produce white residue.

Mixing Procedure:
The staff's response focused on adjusting the ingredients to resolve the issues and did not provide specific mixing instructions for the adjusted formula in this conversation.
