How do day and night creams differ? Do I need a night cream?

In general, night creams are simply thicker than day creams -- and almost all contain oil. Unless you suffer from severely dry skin, chances are you do not need one. If you have moderately dry skin, your best bet is to apply a regular moisturizer as often as you need it. A caveat: Certain creams, such as retinol creams or lightening creams that don't contain SPF, must only be used in the evening as they can cause sensitivity to the sun.
