How much rosehip oil should I drop onto my face for optimal benefits? Considering the various factors such as skin type, the specific concerns one might have, and the overall formulation of the product, this question becomes quite nuanced. Should I be applying just a few drops, or is there a threshold number that maximizes its efficacy without overwhelming my skin? Might the viscoelastic properties of the oil necessitate a careful approach to avoid excessive greasiness? Additionally, how does the application method—perhaps via gentle massaging techniques—impact absorption? Should I perhaps contemplate blending rosehip oil with other serums or moisturizers to create a more synergistic effect? Is there a risk of over-application leading to potential breakouts, especially for individuals with oily or combination skin? Furthermore, what about the varying concentrations of rosehip oil in different products? How does that influence the quantity I should use?
