"I&#039;ve been taking Desogen for almost 1 year now. I get it from Planned Parenthood for about 20 dollars. The only side effects I have seen are a slight headache at the onset of my period and sometimes moodiness around that time as well (I guess it is to be expected anyways). Other than that, I do get dark freckles now when out in the sun. They don&#039;t seem too bad now, but if it gets worse I will switch. This is why I changed from my last brand (think it was Estrostep) because it caused bad facial discoloration whenever I went out in the sun! Looked like I had a mustache for months!"
