One study that gained a lot of traction in the acne vs. food debate appeared in the Archives of Dermatology in 2002.  This research was based on the study of 115 people in Eastern Paraguay and 1,200 individuals in Papua New Guinea. The individuals in this study lived on a diet of self-raised lean meats and fresh plant foods, and scientists were astonished to record not a singular case of acne in either population. Based on this evidence, researchers concluded that the standard Western diet composed largely of starches and refined sugars might be a culprit between the high rates of acne in the Western world.
Inflammation is the single greatest gauge of scar development. The greater the inflammation on the skin, the more likely scarring is to occur. Deep breakouts that take a long time to heal also increase the chance of scarring. Blackheads, whiteheads, and other non-inflamed blemishes typically don't cause scarring because these types of lesions don't injure skin tissue.
Although acne remains largely a curse of adolescence, about 20% of all cases occur in adults. Acne commonly starts during puberty between the ages of 10 and 13 and tends to be worse in people with oily skin. Teenage acne usually lasts for five to 10 years, normally going away during the early 20s. It occurs in both sexes, although teenage boys tend to have the most severe cases. Women are more likely than men to have mild to moderate forms into their 30s and beyond.

Your doctor might recommend an injectable treatment called a filler. "Mainly, I treat acne scars with hyaluronic acid fillers, such as Restylane, but not all acne scars respond to this sort of treatment," Schlessinger says. "Additionally, I personally find that Accutane has a remarkable effect on acne scars if it is prescribed early on in the course of a scarring acne."


Exfoliating. Exfoliating products are used to gently remove dead skin cells that can build up and create a place for acne-causing bacteria to grow. You can purchase an exfoliant or make one using household ingredients. Those with dry skin can add coffee grounds to their regular cleansing product. A standard treatment can be made by creating a paste made from water and baking soda and applying it with a circular motion on the face. Those with sensitive skin can use a gentler treatment by mixing oatmeal with honey and rubbing it on the face for 2-3 minutes before rinsing it away.
Treating acne requires patience and perseverance. Any of the treatments listed above may take two or three months to start working (even isotretinoin). Unless there are side effects such as excessive dryness or allergy, it is important to give each regimen or drug enough time to work before giving up on it and moving on to other methods. Using modern methods, doctors can help clear up the skin of just about everyone.
Experiment with aloe vera. The sap of the aloe vera plant is a soothing natural substance which can be used to relieve many ailments, from burns to wounds to acne scars. Aloe vera helps to rejuvenate and moisturize the skin, encouraging acne scars to fade. It is possible to buy aloe vera products in the drugstore, but the best thing to do is buy an aloe vera plant and use the sap from a broken leaf. This gel-like sap can be applied directly on the scarring, and there is no need to wash off.
Another source of hormonal changes: stress. Whether you work full time, are a full-time mom, or juggle both, chances are, your stress levels are high. "When you're stressed, you have an organ called the adrenal gland that makes the stress hormone cortisol, and puts it out into the body to help the body deal with stress," Dr. Schultz explains. Unfortunately, a tiny bit of testosterone leaks out with it. For a woman, this male hormone can drive the oil glands to produce more oil—the root cause of breakouts. (Thanks a lot, hormones!)
Rouleau also enlightened me about another culprit making my skin care routine less effective: using oil-based products at the beginning of my skin care routine. As Rouleau explained, oils have a large molecule size and, therefore, should go at the end of a skin care routine because it almost acts like a sealant. When you use a cleansing oil or balm first (as I used to do along with makeup wipes), you're basically creating a barrier that makes it more difficult for other skin care products to penetrate and do their job.

Apply fresh lemon juice. Lemon juice has natural skin bleaching properties, and can help to effectively lighten your acne scars. Simply combine equal parts lemon juice and water and apply this liquid directly onto your scars, avoiding the surrounding skin. Wash off the lemon juice after 15 to 25 minutes or you could put the lemon juice on overnight as a mask.

Yet another study took a look at the difference in rates of acne in first-degree relatives between patients and controls. The study used 204 acne patients, and 144 non-acne controls. Their study determined that having a first-degree relative who suffers from acne increases the risk of getting acne by four times. Genes play a role in several ways: firstly, they contribute to skin sensitivity. Acne-prone skin is more susceptible to oil production, and tends to shed and regenerate skin cells faster. Those prone to acne also exhibit strong inflammatory responses to skin irritants and bacteria in comparison to those who don’t have issues with acne.
Sneaky everyday habits could secretly be doing a number on your skin. Even something as seemingly harmless as wearing over-the-ear headphones could be the culprit to breakouts around your temples and jawline. "This is especially the case when you wear them during and after a workout, or if you keep them on for long periods of time," says dermatologist Dr. Debra Luftman. "Sweat and moisture collect on and around the headphones, compressing the skin and therefore encouraging bacteria and yeast to multiply," she says. Gross, but true. Use an anti-bacterial wipe to quickly disinfect your headphones.
All the above remedies for acne scars are good but there are some that will be more suitable for your skin type. Find out them by experimenting with each and every remedy for scars. Have patience and treat your scars with these remedies and you will definitely get rid of your acne scars. Patience will be the main ingredient though, whatever remedy you adopt for your acne scars!

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).
Blackheads are, essentially, open comedones. "Comedone refers to plugging of the follicular opening," explains NYC dermatologist Elizabeth Hale, M.D., referring to hair follicles that technically cover your entire face and body (hi, peach fuzz). "Every hair follicle appears in a sebaceous gland." So a blackhead is the mixture of dead cells, bacteria, and grime that builds up and hardens in the follicular opening—but it's open to the world, which is why blackheads are so easy (read: tempting) to push out.
I can't disagree with much of this. I was almost half expecting some wild remedy. :) When I was younger I had very bad cystic acne. I took tetracycline, minocycline, doxicycline, I used topicals like Retin-A, Cleocin-T, salicylic acid, benzoyl peroxide. I began using the Citrus Clear products on a regular, daily basis. Also I never touch my hands to my face, and the result has been acne free. NOt even an occasional pimple.
Lowering stress levels can have an immediate beneficial effect on the appearance and frequency of acne breakouts. It’s important to maintain a regular exercise routine, get enough sleep every night, and practice stress control methods. Meditation has been shown to alleviate the effects of various skin conditions like eczema and psoriasis, and could have a positive effect on the symptoms of acne.
Smoking, spicy foods, hot drinks, and alcohol may cause flushing and should be avoided. Exposure to sunlight and to extreme hot and cold temperatures should be limited as much as possible. Red wine and chocolate are two well-known rosacea triggers. Some listed foods may have no effect on one patient's rosacea but severely affect someone else. Individual reaction patterns vary greatly in rosacea. Therefore, a food diary may help to elucidate one's special triggers.

7. You smoke. Every time you light up a cigarette, you decrease the amount of oxygen that goes to your face. This not only predisposes you to cancer, and causes the breakdown of collagen and elastin that leads to wrinkles and increased pore size, but the carcinogens in the smoke also irritates your skin and dries it out, triggering your skin to produce more oil and possibly more breakouts. (Tip via Dr. Downie.)

Glycolic Acid is an alpha-hydroxy acid and an exfoliating ingredient that targets both acne and wrinkles at the same time. "The same way it helps acne, it helps wrinkles—by removing dead cells on surface. If you have effective exfoliation, you're stimulating collagen and hyaluronic acid," Dr. Schultz explains. This will help improve skin's texture and reduce fine lines and wrinkles while also clearing up breakouts.
Since the UV rays and visible light from the sun can further darken acne marks, all the dermatologists agree it’s essential to wear sunscreen daily. “Sun protection can make a big difference in whether or not these marks remain permanent,” says Nagler, so much so that she’ll often recommend patients wait and see what their scars look like after a year of careful sun protection before opting for an expensive or invasive procedure. This CeraVe oil-free sunscreen is ideal for acne-prone skin, and also contains niacinamide, which is known to help brighten skin and fight inflammation.
But, sometimes a particularly aggressive blemish is truly on a mission to leave its permanent mark. "Acne scars occur when normal tissue in the skin is destroyed and replaced with fibrous tissue. You can think of an acne lesion as a wound. When the damage caused by acne is severe, the body can respond by creating too much tissue or too little tissue. The production of too much tissue forms a keloid or a hypertrophic scar, and too little tissue leads to that depression in the skin, or atrophic scar. The deeper and more inflamed the acne lesion, or the more that it is picked or squeezed, the more likely it is to scar," says Dr. Bowe.
Doctors can treat telangiectasias with a small electric needle, a laser, intense pulsed light, or minor surgery to close off the dilated blood vessels. Usually, multiple treatments are required for best results, and only a portion of the blood vessels improve with each treatment. Not everyone responds the same to these types of treatments, and a physician can help someone decide which treatment is best for his or her skin type, condition, and size of blood vessels.
The spots that linger after a pimple has healed are caused by inflammation that has disrupted the skin's natural healing process. "When your skin is opened up (like when you pop a pimple) and then closes back together, you can get abnormal pigmentation, texture, and tone that looks different from the rest of your skin. Sometimes the broken blood vessels that remain after an acne lesion fades can result in a mark," says Dr. Bowe. For a number of people who are able to refrain from picking, inflamed pimples or blemishes can still leave a dark brown or red mark — but these naturally fade over the course of a few months, notes dermatologist Heather C. Woolery-Lloyd, MD.
There’s no quick fix for acne. Medicines don't work overnight. Many treatments take weeks of daily use before your skin improves. Some acne may take up to 6 months to clear up. Afterward, basic skin care -- bathing daily and washing your face and hands with mild soap -- may not be enough. You may need to keep using your medicine even when your skin clears. Follow your doctor’s directions. Don’t use too much or too little.
"Put it this way: It is so common that pimples are meeting wrinkles," dermatologist Neal Schultz, M.D., creator of Beauty Rx Skincare, tells SELF. "For the last 10 to 20 years, adult acne has been increasing. It can even go into your 50s, right to menopause." If you had acne as a teen, chances are, you've got oily skin that's prone to breakouts. But even if you didn't, it's still possible you'll end up with adult acne.
Scars that are indented aren't going to go away on their own and most likely need professional treatment. Talk to your derm about laser options, as well as subcision and microneedling—all proven methods to get rid of scarring. But those brown spots left behind once a zit goes away? You can treat them at home if you're diligent. Dr. Schultz says you have to stick to a regimen of daily sunscreen use, exfoliation, and application of a bleaching product that will help remove the excess pigmentation in the skin. Try Murad Rapid Age Spot and Pigment Lightening Serum.

As far as combination scars go, Dr. Levine’s go-to acne scar treatment for combination-type scars include a series of treatments with picosecond lasers such as the Picosure or use of the FRAX 1550* Fractional non-ablative laser. “These are newer technologies, and they have less downtime than older lasers, so for me this means I can be more aggressive and see results with fewer treatments.” Older ablative lasers blast off the skin’s top layers, which requires significant downtime, but these newer non-ablative lasers pass through the skin’s upper layers to harmlessly heat the deeper tissues, stimulating collagen and smoothing the scar’s appearance.
How big of a scar you'll be left with after a blemish (if any at all) depends on the depth of the breakout, Schlessinger says. "As our pores become engorged with oil and form a blemish, the pore may swell and collapse the follicle wall," he says. "The depth of the resulting lesion determines the severity of the scar. Shallow lesions usually heal quickly and leave little-to-no scarring, while deeper lesions spread to nearby tissue, causing a more pronounced scar."
Dermal fillers: "Certain scars can be filled with a substance that elevates the depressed areas, like hyaluronic acid. This can make the surface of the skin more even and get rid of shadows," says Dr. Bowe. Until recently, fillers weren't a lasting solution. But now, if you're over 21 years old, Bellafill is the first FDA-approved dermal filler designed for permanently correcting moderate to severely dented acne scars. Unlike other fillers, it contains two different ingredients to help improve acne scarring. "It's 20% polymethylmethacrylate (PMMA), which helps your body make more protein to allow itself to heal," says Dr. Shah. "PMMA are tiny balls that sort of act as a scaffolding. Most fillers degrade over time, but since PMMA cannot be absorbed into the body, this offers a permanent result," she says. The other 80% is collagen. The procedure takes about 20-30 minutes, and while you may need a touchup a couple months later, some people just need the single treatment, says Dr. Shah.
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.
What you can do differently: For starters, stop going to tanning beds. Period. And if you are in the sun, make sure to slather on a titanium dioxide- or zinc-based sunscreen (these are natural sun protectants and their formulations usually contain fewer chemicals, so they won't break you out as easily), and wear a sun hat or ball cap to shield your facial skin from harsh rays.
Some people swear by the disinfecting power of tea tree oil for acne treatment. It can be applied either full strength or slightly diluted with water directly onto pimples. Use a small amount on a clean cotton swab or cotton pad and dab on the affected areas immediately after cleansing. Because tea tree oil can be drying, you might choose to use both tea tree oil and coconut oil for acne as part of your clear skin regimen.
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.
