What ingredients can help make facial skin appear plump and hydrated, specifically without causing an oily look?
I am having significant issues with dissolving/emulsifying an O/W serum using a cold process. The formulation contains high levels of actives in both the oil and water phases: * **Oil Phase Actives:** * Tocotrienol 2% * Pure CoQ10 0.5% * Ascorbyl Tetraisopalmitate 3% * **Water Phase Actives:** * L-Ascorbic Acid 15% * DMI 10% * Pentylene Glycol 10% * 1,2-Hexanediol 5% I am using basic equipment like a magnetic stirrer, hot plate, and accurate scale. I am looking for a clean, green, and EWG-friendly emulsifier/solubilizer, ideally without involving heat. I have tried Polysorbate 20 and 80, but the oil still separates after a short time.
