Detailed answer

No, body oils should not be used on rough knees on the face. Body oils are typically designed for use on the body and may not be suitable for the delicate skin on the face. The skin on the knees is thicker and more resistant to irritation, while facial skin is thinner and more prone to sensitivity. Using body oils on the face may clog pores, lead to breakouts, or cause irritation. It is important to choose products specifically formulated for the face and to consult with a skincare professional for personalized advice and recommendations.
