I don't have all the facts but can indicate for you to search further. Ideally, one is not supposed to use body lotion on the face because the size of molecules(?) are larger in the body lotion and are not right for the delicate skin of the face. But in India, most people use one lotion/cream for everything! Check out and share the info with all.
I feel all this is just marketing strategy. One cream for face,one for eyes,one for hands ,one for body ,one for feet. cosmetic company is laughing all the way to the bank. The body lotion might be more oily for the face. If you are using a lighter body lotion ,it should be fine.Try it and see for a few days.
The rare occasions that I have used body lotion on my face I have been left looking like dakoo Sher Singh, one big pimple located right on the cheek or the nose . I have a oily skin so that might contribute to it as well.
I don't think so!!! Our facial skin is much more sensitive and a body lotion cannot take enough care of it. We need a cream depending on our skin type.
