You wouldn’t think that using moisturizer is a way to assist in acne treatment, but it actually can be very helpful, especially if you are using a treatment that is stripping all the oils and moisture out of your skin.  Your body is just reacting by producing more oils to compensate for what it thinks is happening.  Then you are actually going to get the opposite effect from what you think you are getting.  You will get more oil not less. 

So my applying a good moisturizer you can add back in the good oils that your skin needs to stay soft without creating the blemishes.  Oh, and you also need one with a sunscreen.  That way you are also getting the added protection that will also help in preventing wrinkles and skin cancer.  All this in just one little moisturizer.  And obviously if you tend to have acne issues pick a moisturizer that is made especially for oily skin.  This way it is adding in the right kinds of oils into your skin and not adding to your problems.  Apply the moisturizer both morning and night.  That way you always have the right protection for your skin..  Your skin will also get use to this and become accustom to it.
