I have PCOS and also have aconthosis on my neck and arm pits. I am currently on a contraceptive pill - Yasmin for 3 months. I want to know will that make aconthosis worse? Also, how can I fix my aconthosis. I'm taking canthex capsules in the morning and evening after food. I used a few creams but it made it even more dark and burnt - it was glyco and tretin. What should I do? Whats the best possible solution for aconthosis while on Yasmin. How do I fade away aconthosis.. I have started diet and exercise also - it's been 2 months. Trying to lose weight but my neck is just getting darker. I checked my diabetes - I don't have diabetes.
