Gel Serum Formulation for Oily, Dehydrated, Acne-Prone Skin: Ingredient Review and pH Adjustment

Here is the analysis of your revised formula for a gel texture intended for skin nourishment:

• Pro Polymer: The concentration of 5% is too high. The staff recommends using only 1%, which should be sufficient to create a gel texture.
• Ingredient Suitability: The staff suggests that the selected ingredients might not be optimally suited for skin that is oily in the T-zone, dehydrated, and prone to clogged pores. They recommend focusing on ingredients that help control oiliness and balance the skin, such as Zinc PCA, Safe-B3 (Niacinamide), Licorice Extract (already included), AcneBee, Rice Vitamin, and other ingredients from the "oil control" category. These ingredients help manage excess oil without drying the skin and provide moisture to dehydrated areas.
• Nourishing Ingredients: While nourishing ingredients can be used, high concentrations might lead to a sticky feeling, especially for combination skin. The staff believes Natto Gum is not necessary for this skin type, and the concentration of Active Resveratrol should be reduced.

Regarding checking pH:
Yes, it is necessary to check and adjust the pH of the formula. This is particularly important when using Pro Polymer, an acrylate crosspolymer gelling agent, which often requires pH adjustment to form a proper gel. Additionally, some active ingredients have specific pH ranges for optimal efficacy and stability. Checking and adjusting the pH ensures the formula is stable, effective, and gentle on the skin. The ideal pH range will depend on all the ingredients used in the formula.

In summary, your revised formula can be made into a gel by reducing the Pro Polymer concentration. However, to better address your skin concerns, you should consider adjusting some nourishing ingredients and adding oil-controlling ingredients as recommended by the staff.
