Detailed answer

Facial oils that are heavy and occlusive can create a barrier on the skin, preventing proper exfoliation and the natural shedding of dead skin cells. As a result, these dead skin cells can accumulate on the surface, leading to a lack of radiance and dullness. Additionally, if the facial oil is not properly absorbed or if it is comedogenic, it may clog pores and cause breakouts, further contributing to a dull appearance. It's important to choose facial oils that are lightweight, non-comedogenic, and easily absorbed to avoid these issues and maintain a radiant complexion.
