Hello, I have an eczema. Usually most part of my body is always itchy, especially when im sweating. Some part of my body has a dry wound and and dark spot or skin like my ,hips,calfs and arm and on the other hands there is places which are genuinely an eczema spot like on the buttocks. My question is, if i were to buy those lotion and moisturizer to treat my eczema, do i have to apply the lotion all over my body or just the itchy spot? Can i apply a regular lotion on the normal itchy spot and eczema lotion for the eczema spot or do i need to apply the eczema lotion for the eczema spot and the normal spot?
