Feedback and Mixing Instructions for Pudding Texture Serum Formulation

Subject: Feedback on Cosmetic Formulation

Thank you for sharing your cosmetic formulation for combination to slightly oily skin, targeting brightening and strengthening with a pudding texture.

Here is a summary of your proposed formula:

• Part 1: Yeast Radiance 3%, Repair Activator 10%, Matrixyl 3000 (Pal-GHK, Pal-GQPR) 5%, Safe B3 5%, Mild Preserved Eco 1%, Water Lock 1%, NAT-RIBOSE 1.5%, Pro Polymer 3%, Water 65.5%
• Part 2: Phytosterols (Plant Sterols) 5%
• Part 3: Zinc PCA 1%

Mixing instruction: Mix Part 1 and 2 together, then add Part 3.

The staff has reviewed your formula and provided the following feedback:

• Texture: Using Pro Polymer at 3% is suitable for achieving a pudding-like texture. However, due to the high concentration, a blender is necessary for proper mixing; manual stirring may not be sufficient.
• Ingredient Suitability: Overall, the selected ingredients are considered appropriate.
• Potential Redundancy: The staff noted that Water Lock and Phytosterols might be unnecessary for skin that is slightly oily. Similarly, Zinc PCA might not be needed if the skin is not oily. The staff pointed out a potential contradiction between the user's description of the skin being slightly oily and the inclusion of ingredients typically used for less oily or acne-prone skin.
• Mixing Steps: The recommended mixing procedure is to combine the water phase ingredients from Part 1 (excluding Pro Polymer), then add Pro Polymer and blend thoroughly until it is completely dissolved (which will take longer due to the 3% concentration). After this, combine with Part 2 and then add Part 3.

Please consider the staff's comments regarding the potential redundancy of certain ingredients based on your specific skin condition.
