Formulation Feasibility

Yes, the proposed formulation using Rose Hip Oil as a base with Vitamin A, Vitamin C Ester (L-Ascorbyl Palmitate), and Vitamin E Acetate is feasible for addressing acne and wrinkles, as confirmed by the previous expert advice.

Important Considerations

• Vitamin C Ester (L-Ascorbyl Palmitate): As noted, this ingredient is a powder and may require gentle heating and stirring to fully dissolve into the oil base.
• Heat Sensitivity: All the ingredients in your formulation, including Rose Hip Oil, Vitamin A Palmitate, Vitamin C Ester, and Vitamin E Acetate, are sensitive to heat. Use only minimal, gentle heat if necessary to dissolve the Vitamin C Ester, and avoid prolonged exposure to high temperatures to preserve the efficacy of the vitamins and oil.
• Storage: To maintain the stability and effectiveness of the formulation, store it in a cool place away from direct light and heat.
