Will my moms Jergens Age Defying lotion work for my face?

DON'T use age defying or wrinkle creams of any sort on teenage skin, they can cause breaking out! They're designed for more mature skin and won't work well. Rinse your face with warm water, then apply any plain lotion you have around if there are no other face creams such as a body lotion. Hope this helps, and try getting a new lotion like the aveeno daily moisturizer.
