Why so many different types of moisturizers? It's because the characteristics of your skin vary quite a bit from area to area. The most effective moisturizer for dry hands, for instance, will be a lot heavier than what most of us would want on our face.
Facial
Moisturizers
These are the lightest preparations, designed to moisturize without making your face feel oily.
Body
Moisturizers
A thicker, creamier grade of moisturizer for areas other than the face.
Hand
Moisturizers
The thickest of all, to penetrate and repair rough, dry skin on the hands.
