Common acne, known medically as Acne Vulgaris, is generally caused by hormonal changes in the body, and its onset usually can be found in teenage years when puberty rears its head. Acne is directly attributed to the rise of androgen hormone levels. The production of these hormones rise when a child begins puberty, and is the reason much acne is prevalent in adolescence. As androgen levels rise, the oil glands sitting directly underneath the skin enlarge and produce increased levels of oil, also known as sebum. When pores are filled with excessive sebum, it can cause surrounding skin cells’ walls to rupture and create a breeding ground of P. acnes bacteria. As the sebum attempts to push out of the pore, it can attach to this infectious bacteria and dead skin cells, causing a blockage that begins the formation of a pimple. According to Medical News Today, dermatologists purport that almost three quarters of 11 to 30-year-olds will deal with acne at some point, but acne breakouts can continue on into adulthood, and have been observed in patients in their fifties.
Sunscreen: "Sun exposure during an active breakout can lead to darkening of inflammatory lesions, prolonging their appearance on your skin and making them harder to fade over time," says Dr. Shereene Idriss from Union Square Dermatology, which means it's important to lather on the sunscreen daily — even when it's cloudy. And don't worry about breaking out from a pore-clogging sunscreen; the latest formulas are more innovative and acne-friendly than ever. Elta MD UV Clear Broad-Spectrum SPF 46 is a top derm-approved favorite. It contains niacinamide, which is an anti-inflammatory that helps reduce redness.
Treat Acne As Soon As It Develops: The best thing you can do is get acne under control as soon as possible. Begin treating it right away, and see your doctor immediately if your acne isn't getting any better with over-the-counter acne treatments. Quick treatment helps to keep breakouts to a minimum and prevents acne from developing into a more severe form.  Prevent pimples and you'll prevent scarring.
If there are multiple ice pick scars, acne scar treatment devices that use radiofrequency energy are Dr. Hellman’s first choice. “These treatments help build collagen from the inside out, and collagen helps to fill the scars from within,” she says. Several treatments are usually needed. The procedures are done using local anesthesia, and it’s effective in all skin types, she says. In one study, published in a 2015 issue of the Journal of Cosmetics, Dermatological Sciences and Applications, Dr. Hellman found that approximately four treatments with a radiofrequency device produced significant improvement in the depth of the scars. A follow-up study in a 2016 issue of the same journal showed that these results held for up to two years, although some people had touch-ups.
Isotretinoin has a high risk of inducing birth defects if taken by pregnant women. Women of childbearing age who take isotretinoin need two negative pregnancy tests (blood or urine) before starting the drug, monthly tests while they take it, and another after they are done. Those who are sexually active must use two forms of contraception, one of which is usually the oral contraceptive pill. Isotretinoin leaves the body completely when treatment is done; women must be sure to avoid pregnancy for one month after therapy is stopped. There is, however, no risk to childbearing after that time.
Light treatments: Recent years have brought reports of success in treating acne using special lights and similar devices, alone or in conjunction with photosensitizing dyes. It appears that these treatments are safe and can be effective, but it is not clear that their success is lasting. At this point, laser treatment of acne is best thought of as an adjunct to conventional therapy, rather than as a substitute.
A benzoyl peroxide cream (2.5 percent strength) is a good choice for adolescents experiencing red or inflamed breakouts that aren't getting better with medicated cleansers. Benzoyl peroxide is a very common and inexpensive acne treatment cream that can be found over-the-counter in the skin care aisle. Benzoyl peroxide kills the bacteria that cause pimples and is highly successful in treating mild cases of acne.
While acne is a much more visible condition than most, it is important to remember that it is like most diseases, in which early detection can help to mitigate its impact. Bearing that in mind, we have taken the time to put together 10 of the most common causes for acne, so that you can be better informed and potentially avoid some (and only some) of its root causes.
Acne is reported to be less common in people that have a diet with lower glycaemic index, eg, natives from Kitava and Papua New Guinea, the Ache people of Paraguay, Inuits and rural residents of Kenya, Zambia and Bantu. These people tend to become sexually mature at a later age than in the cities where higher glycaemic index foods are consumed. Early puberty is associated with earlier onset and more severe acne that tends to peak at the time of full maturity (age 16 to 18).

The hair follicles, or pores, in your skin contain sebaceous glands (also called oil glands). These glands make sebum, which is an oil that lubricates your hair and skin. Most of the time, the sebaceous glands make the right amount of sebum. As the body begins to mature and develop, though, hormones stimulate the sebaceous glands to make more sebum.

Rosacea is considered an incurable auto-inflammatory skin condition that waxes and wanes. As opposed to traditional or teenage acne, most adult patients do not "outgrow" rosacea. Rosacea characteristically involves the central region of the face, mainly the forehead, cheeks, chin, and the lower half of the nose. It commonly appears in people with light skin and particularly in those of English, Irish, and Scottish backgrounds. Some famous people with rosacea include the former U.S. President Bill Clinton and W.C. Fields. Alcohol intake does not directly cause rosacea, but it can be aggravated by it. Rosacea is not contagious or infectious.
When it comes to skin care, we're not usually ones for hard and fast rules. Everyone has unique skin types, skin tones, lifestyles, and genetic histories that make it impossible to have a single piece of one-size-fits-all advice. It can take years — and dozens of trips to the dermatologist — to discover how to treat acne effectively on your unique skin. But here at Teen Vogue, we've pretty much made it our life mission to figure out the best tips from the pros to point you in the right direction. They've seen it all and won't recommend it unless it's backed up by experience and science,.
Sometimes, your gynecologist can share insight into your acne, especially when it comes to deciding if birth control could help your breakouts. The FDA approves of Estrostep, Ortho Tri-Cyclen and Yaz to combat acne, but the trick is to be patient, as it can take up to four months to start seeing results. "This plan of attack works best when paired with whatever topical treatments you’re already using to treat your acne, like Proactiv, benzoyl peroxide, salicylic acid, etc," advises dermatologist Dr. Elizabeth Tanzi.

The best way to fix them: This is where the classic zit treatments come into play. "Topical medications are the best way to treat a lesion like this," says Jennifer Chwalek, M.D., a dermatologist at Union Square Laser Dermatology in NYC. "Benzoyl peroxide-, salicylic acid-, or sulfur-based products can help to dry it up." She prefers salicylic acid over benzoyl peroxide for these, since the latter can cause irritation, dryness, and even post-inflammatory hyperpigmentation (a.k.a. dark spots) in those with darker skin tones. Retinol works well for these, too.

Baldwin says squeezing is the best way to get rid of blackheads, but it should be left to a professional if possible. “A good cosmetologist can do an awesome facial," she says. “Pore strips can also help. But both of these are made much easier by starting on a retinoid first. Prescription retinoids soften the pore contents and make the whole process more successful and less painful. With time they will also eradicate the blackheads." The best way to get rid of blackheads for good is with a skin care regimen and the best acne products for clearing the pores. Do not try to pop blackheads or dislodge the blockage with your nails, as your hands may introduce new bacteria to the pores. Instead, see how to get rid of acne fast and prevent blackheads with these acne treatments:
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.
In order to treat acne marks and scars, it's helpful to learn how to distinguish between the two. "What many people don’t realize is that a dark or pink mark on the skin is not actually an acne scar. Inflammation in the skin often leaves behind a stain as part of the natural healing process. The inflammation revs up pigment production, creating the mark that fades on its own over several weeks to months," says dermatologist and 2018 Acne Awards judge Dr. Joshua Zeichner. Unlike scars, these are smooth to the touch (AKA, not raised or indented), and signify that there is no permanent collagen damage to the skin.

Treatment of acne scars: For those patients whose acne has gone away but left them with permanent scarring, several options are available. These include surgical procedures to elevate deep, depressed acne scars and laser resurfacing to smooth out shallow acne scars. Newer forms of laser resurfacing ("fractional resurfacing") are less invasive and heal faster than older methods, although results are less complete and the procedures may need to be repeated three or more times. These treatments can help, but they are never completely successful at eliminating acne scars.
