I recommend a body lotion that you can apply while showering.

The product name is Nivea In-Shower Body Lotion. It is a product you apply while your skin is still wet, after washing it off with body wash, and then rinse it off. It is a hassle to apply lotion after finishing a shower, but it is better to apply it during the shower. Since it is Nivea, the moisturizing power is, of course, excellent.
