Succulents naturally lose their outer leaves/petals as they grow. Some will simply begin to shrivel up while other types may turn a translucent color and fall off as well. If there are some shriveled or unpleasant leaves/petals on your plant, just simply and gently remove them! Toss them in the trash! But… succulents do not naturally lose their top or center leaves. These are their fresh growth areas. Please send us a picture if you are having a problem there so we can help you assess the potential problem.
