"Other good over-the-counter options are benzoyl peroxide-containing agents," says Dr. Engelman. "I like La Roche-Posay Effaclar Duo. Benzoyl peroxide is anti-microbial, attacking the bacteria that is associated with acne. The La Roche Posay product also contains Lipohydroxy acid (LHA), which serves as an exfoliator to smooth roughness and even out skin texture."
Cysts, which are also called blind pimples, are the very worst kind of acne. Basically, cysts are made up of sebaceous content (again, a gross combination of oil, dirt, and bacteria) that's trapped beneath the skin and has no way out—so they just live and grow under the skin, causing both a bump and, in some cases, pain. "These take longer to resolve on their own, are less responsive to topical treatments, and over time may lead to scarring," says Dr. Chwalek. Um, no thanks.
A recent study has found a difference between strains of acne bacteria, which could have a significant impact on acne treatment down the road. This study, published in the Journal of Investigative Dermatology, found that these strains play a role in the severity and frequency of developing pimples. One particular strain of P. acnes was found among study participants that exhibited few symptoms of acne. Researchers came to the conclusion that this “good” strain of bacteria features a natural defense mechanism that fights back bacteria which might infect the cell. Researchers are hopeful that this discovery will help dermatologists better and more accurately prescribe effective acne treatment in the future, and reduce the severity of acne by ridding the skin of bad acne bacteria while preserving the good. 
So if popping pimples doesn't cause scarring, what does? Long-lasting scars typically turn up after a recurring bout with cystic acne. Cystic acne is a breakout that burrows deep into the skin. These red, painful nodules occur when clogged pores are filled with pus and bacteria, which causes inflammation. Cystic breakouts are often tied to an internal fluctuation of hormones like testosterone (that's why they're common during puberty, monthly menstruation, and perimenopause). "If there is a cyst in the skin, it's going to cause a scar the longer it sits there because pus or bacteria deeper inside the pores cause surrounding inflammation," says Dr. Karolak. And as a result, the inflammation affects the collagen production as well as the fat stores under the skin, creating a visible scar on the surface.
Inflammatory Acne: Inflammatory acne is red bumps and pustules, not whiteheads, blackheads and comedones. It does not necessarily start as them, either. It arises on its own. Whiteheads, blackheads or comedones that become inflamed can be painful and unsightly. Persistent inflammatory acne may require treatment by a physician or dermatologist, in addition to over-the-counter acne remedies.
If you have body acne, taking a shower as soon as possible after working out is also key. It turns out that standing around in tight, sweaty workout clothes puts you at the greatest risk for body acne and rashes. “The whole idea is that the bacteria that live on the skin can get trapped in the hair follicles and cause inflammation,” says dermatologist Dr. Elizabeth Hale. “The more you work out in the heat the more likely this is.” Dr. Levin agrees that showering right after a workout is your best defense against body acne. But in a pinch, body wipes like the Yuni Shower Sheets will do the trick.

Ans: When the follicle or pore becomes clogged due to excess oil, bacteria and dead skin cells then the pores swell by causing a break in the follicle wall. If the rupture occurs near the skin’s surface then lesion will be minor and gets healed quickly. Then this infected material extends into the dermis and destroys the healthy skin tissue then it forms scars on the skin.
Exfoliating cleansers and masks: A variety of mild scrubs, exfoliants, and masks can be used. These products may contain salicylic acid in a concentration that makes it a very mild peeling agent. These products remove the outer layer of the skin and thus open pores. Products containing glycolic or alpha hydroxy acids are also gentle skin exfoliants.
