Is it safe to use Retin-a .05% at night after cleansing, and then not wash off again until the next night?

I have pretty dry skin and I am trying to fix some sun damage around my eyes. I have mild acne and I use sulfacetamide 10/5 cream on areas where I suspect blemishes are arising. I have found washing only once a day at night helps my facial skin feel more comfortable. I am not sure though if I absolutely should wash off the retin-a in the morning even though I am using a spf 34 Skinmedica product during the day. Any professional opinions would be helpful.
