Cosmetics Formulation Development

Please inquire I want to make products for skin massage. Questions are: 1. Should I be a cream or a serum? In order to be absorbed into the skin easily and not sticky. 2. Ingredients I have. น้ำมันมะพร้าว is the main thing I should use. Which substance makes the oil mixed into the cream/serum and is not sticky and easily absorbed into the skin? I've tried mixing carbopol and it's very sticky. Please suggest. thank you
