Any medicine to cure pimples?  

Use toothpaste. No, I'm not even kidding, seriously it works! Leave it overnight or something.
(your skin may look a bit redder after but use tea tree oil for that..)

Hi rsgi009. Acne can really be annoying.I had them when I was younger,in my teens, and even now at the age of 33, I still tend to get them occasionally.I know when I will get them though and sometimes that helps in preventing them.I develop an occasional pimple or two when the weather is really warm.I will sweat and it will cause them.Also when I am very stressed out.
Another way,which I'm sure isnt why you've gotten them, is monthly when my hormones change!
Now, you definitely could've gotten them from the change of climate.
I have tried many things on the market and the best I know that really works for me is this.I wash my face in the morning and at night before bed.I dont use regular soap as it can dry out your skin badly.I use a nuetrogena bar.Nuetrogena makes very good skin products.When washing my face I use hotter water to open my pores.Then when I am done I wet it with cooler waterto make them tighter again.
Benzoyl proxide is a common ingredient found in my otc medicines for acne.You can use this after washing your face.Dont use to much at first because your skin must get use to it.Benzoyl peroxide can dry your skin out badly.I would reccommend once or twice daily.
As long as you are dedicated and do this daily it should help.If not you can always go to a dermatologist.
Hope this helps any!
