DO NOT POP YOUR PIMPLES! you will regret it in the future…just aviod picking them at all costs! you said u want to aviod acne scars, popping your pimples is what causes acne scars.
if you mild acne…a few bumps/blackheads then do not go with proactiv…this is for people with moderate acne…proactiv contains benzoyl peroxide (kills acne causing bacteria) which can really irratate the skin…so if your skin is sensative it may cause a bad reaction. i used proactiv when my pimples were not bad…and even though it helped, it irratated my skin like mad..i wouldnt use it again. however, everyones skin it different. what works for one person may not work for the other. so you can try it if you want, but like i said if your acne is mild, don’t use it!
for your blackheads the BEST thing to use is st ives apricot scrub for blackheads and blemishes. you can get it at your local drugstore…somewhere like target. make sure to be gentle with the scrub, don’t try to scrub away the acne..that will only aggravate it.

also make sure that you drink at least 8 glasses of water a day…this will work wonders for your skin. water cleanses your body and delivers nutrients to your body…it rejuvinates u and it GREATT for the skin.
if your breakouts are due to hormones, try taking fish oil capsules….this will balance your hormones.
some more tips:
make sure u are stress free! this is a leading contributor to acne
make sure you get a good nights sleep…your skin heals itself while you are sleeping
excersize! great for maintaining good health and skin
**acne is not caused by outside bacteria and dirt, this is a common misconception…if it were true all contruction workers would breakout like mad. acne is caused internally…meaning something in your body is not functioning the way it should be. eating healthy is extrememly important.
