Clearasil, etc will probably just bring the acne out more anyway.
A Dr/FNP could prescribe a light, daily dose of antibiotics to help clear it up. If you can't find anything to help.
Adult Acne is extremely common, and was routinely treated when I worked at a derm. office.
I also get splotchy once a month, so the whole world knows my cycle just by looking at my face. LOL! I have also seen it mid-cycle during extremely stressful times. Most of my "spots" occur around my mouth/chin area, which could be caused by my propping my face up with my hands so much while reading.
I found this site, maybe it can help you. It says, stress and diet can cause it, as well as list ways to help it, either by meds (Accutane) or natural items obtainable at a nature/health supply store, etc.
OH...for the time being, even though it would probably hurt it more than help, there is a green-lipstick style cover up you can use on the spots, then put on your foundation.
If things get too bad, dab a little bit of hydrogen peroxide on each sore.
