Like microneedling, fractionated skin resurfacing sends skin a signal to respond to damage. Specifically, microscopic columns of injury are created causing minute perforations in the treatment area, while leaving healthy surrounding tissue intact and untouched. "The specific zones of injury trigger the patient's natural neocollagenesis (collagen rebuilding process)," explains Engelman, who characterizes the treatment as both revolutionary and non-invasive. This new collagen rejuvenates the skin and improves its appearance. "Improvements continue over time (up to six months post-procedure) as new collagen continues to rebuild," she says.

It is a myth that women get acne because they don't wash enough. Too much washing or scrubbing the skin harshly can make acne worse. And washing away surface oils doesn't do much to prevent or cure acne, because it forms under the skin. The best way to clean the face is to gently wash it twice a day with a mild soap or cleanser. Be careful to remove make-up without harsh scrubbing.
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.
Yes, it is possible to lessen, if not completely eliminate, your acne troubles with food. The key is knowing which foods help -- i.e antioxidant rich, fiber packed, protein loaded, vitamin soaked, healthy fat filled foods (that was quite a mouthful, wasn't it?) -- as well as which foods are really, really BAD for acne; i.e. sugar loaded, preservative packed, salt soaked, unhealthy fat filled foods.
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. 
Rolling scars can look like little saucers, giving the skin a wavy texture. Lasers that resurface the skin are Dr. Karolak's top treatment pick for this type of scar, and Dr. Sobel agrees. "Many scars can be improved with lasers such as the matrix CO2, which remove the outer layers of skin, burning away the scar tissue and stimulate new collagen production," he says. "Non-ablative lasers such as the Fraxel can help activate the production of collagen without damaging the surface of the skin." Keep in mind, that these laser treatments can take a bit of recovery time and require multiple treatments to see results. For a quicker solution, your dermatologist can plump the bowl-like scar with fillers like Juvederm, Restylane, or Bellafill.
Even if battling zits is a distant memory, filed away with high-school gym class and algebra tests, acne marks and scars can annoyingly linger long after pimples are gone. “If someone gets a very large pimple or cyst, the natural healing process of the skin will create a scar,” says David Avram, M.D., of Heights Dermatology and Laser. “The more intense the inflammation, the more likely it will leave a scar.”
Sure, we’ve all heard that toothpaste or rubbing alcohol can help dry out a zit, but many DIY treatments aren't solutions for how to treat acne. In fact, applying toothpaste or rubbing alcohol are more likely to cause irritation and dryness than treat the actual pimple. Instead, stick with topical over-the-counter and prescription spot treatments with salicylic acid or benzoyl peroxide that are specially made to target pimples, says Dr. Hammerman. For an all-natural spot treatment, she suggests dabbing tea tree oil on the area a few times a day with a cotton ball.
Acne occurs when the small pores on the surface of the skin become blocked with oil, dead skin cells, and bacteria. Each individual pore on the skin opens up to a follicle beneath the epidermis. Within these follicles lie a singular hair and a sebaceous gland. The sebaceous gland produces sebum, an oil designed to keep your skin lubricated and soft. However, when hormonal changes and other factors cause the gland to produce an excess of sebum, the oil will be pumped through the follicle, and may pick up dead skin cells and P. acnes bacteria on its way out. Should these substances clump together, a plug will form. As this plug starts to press up against the surface of the skin, the body responds with an accumulation of red and white blood cells to combat any infection, and this results in inflammation and redness. Acne can occur on the face, back, neck, chest, arms, and buttocks, and any other skin area with a saturation of sebaceous pores.

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.
With a blend of potent antioxidants, this serum is loved by beauty editors and dermatologists alike. Vitamin C plays a leading role: "The powerful ingredient has been shown to brighten dull skin and lighten brown spots. It may also be helpful in lightening a dark scar," says Joshua Zeichner, the director of cosmetic and clinical research in dermatology at Mount Sinai Hospital in New York City. The formula also includes vitamin E. "Vitamin E is a fatty vitamin that has both antioxidant and skin-protecting properties. It helps seal cracks in the outer skin layer and may help repair a damaged skin barrier and improve the appearance of scars after the initial wound has healed," Zeichner says.
Some of us are more at risk for acne scars than others, although there is no way to say for sure who will develop scars after acne and who will not. These scars tend to occur more commonly after inflammatory acne, especially when it’s not treated early and aggressively. Other risks include picking squeezing or popping zits. (But whatever you do, never, ever pop a zit in the “danger triangle.”) Genetics can also play a role. “The earlier that acne gets treated, the better,” says Dr. Levine. “If somebody has active acne at 13 or 14, we want to jump on it.” Some scar resurfacing treatments also help keep acne at bay, she says. Dr. Imber adds that Youth Corridor RetinUltimate Transforming Gel applied twice daily can help treat active acne and prevent recurrence. Next, find out how to get rid of acne once and for all.
Chemical peels: "A chemical peel is a treatment that uses the application of mild solutions for skin refinement and regeneration. Products containing glycolic acid promote cell turnover, which is the process where new skin cells form and help even out your skin tone," says Dr. Bowe. You can try an at-home peel like Peter Thomas Roth 40% Triple Acid Peel, which uses both glycolic and salicylic acids to help fade spots by exfoliating dead skin cells and smoothing out skin texture. "Or, your dermatologist can prescribe you a stronger peel based on your skin type and treatment goals," says Dr. Bowe.

"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."
The exact cause of rosacea is still unknown. The basic process seems to involve dilation of the small blood vessels of the face. Currently, health researchers believe that rosacea patients have a genetically mediated reduction in the ability to dampen facial inflammation that is incited by environmental factors such as sunburn, demodicosis (Demodex folliculorum in the hair follicles), flushing, and certain medications. Rosacea tends to affect the "blush" areas of the face and is more common in people who flush easily. Additionally, a variety of triggers is known to cause rosacea to flare. Emotional factors (stress, fear, anxiety, embarrassment, etc.) may trigger blushing and aggravate rosacea. Changes in the weather, like strong winds, or a change in the humidity can cause a flare-up. Sun exposure and sun-damaged skin is associated with rosacea. Exercise, alcohol consumption, smoking, emotional upsets, and spicy food are other well-known triggers that may aggravate rosacea. Many patients may also notice flares around the holidays, particularly Christmas and New Year's holidays.
Our skin contains millions of small sebaceous glands underneath the surface. These glands excrete an oil, called sebum, that helps to keep our skin smooth and supple. This oil is released via pores, which are small holes on the surface of the skin, which is also where hairs grow out of. When the body produces a lot of sebum, the skin can feel oily and these pores can become clog. It is when these pores become clogged that germs and bacteria can thrive and grow. The result – pimples.
There is also a role for Bellafill and other injectable fillers, including fat, for some depressed scars. Bellafill is currently the only filler that’s approved by the U.S. Food and Drug Administration to help raise depressed scars. It packs a one-two punch by adding volume, and also encouraging collagen formation beneath the surface by creating a supportive scaffold. “Bellafill and other injectables can fill in scars but these tend to be better for one scar,” adds New York City facial plastic surgeon Jennifer Levine, MD. Filler results can last up to 18 months. “If you have a cheek full of depressed scars, it’s better to resurface the face with laser, radiofrequency, or another energy-based treatment,” she adds.
Not for those with moderate to severe acne: Facials are effective in removing comedones (whiteheads and blackheads), but aren’t for those with many pimples, or inflammatory acne. Exfoliants help reduce comedones, but they frequently irritate pimples — causing them to become more inflamed and noticeable. Also, extracting inflammatory acne, like nodules and cysts, can be very challenging and when done improperly, can lead to scarring or further inflammation.
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.
Spot treatments are key for treating a pimple ASAP. Benzoyl peroxide is often vilified for being harsh, but when it comes to really zapping a zit, it should be your best friend. Just dab it on the trouble spot to dry it out and kill bacteria. For heavy-duty action, try Neutrogena Rapid Clear Stubborn Acne Spot Gel; for something gentler, we like Arithmetic Acne Control Complex, which has soothing ingredients to counter the drying effects and is made with adult skin in mind.

What you can do differently: When washing and conditioning your hair in the shower, tilt your head over to the side to keep the product's residue off your face, chest, and back as you rinse it away. And be sure to wash your face last when you're in the shower to make sure you haven't accidentally gotten any product on your skin that could break you out later.


A good way to lessen constant acne is to improve your lifestyle choices. Try to maintain a fresh and healthy diet, incorporating a lot of fresh fruits and nuts. Try your best to avoid dairy products and any packaged foods. The more fresh the food is, the better it is for your skin. Exercise is also a vital component in the maintenance of healthy skin. Try to complete some form of cardio for at least 30 minutes a day, 3-4 times a week. If none of this is successful, consider consulting a dermatologist.
"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."
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.
This lightweight, all-over acne treatment clears acne with two percent salicylic acid—the highest percentage allowed. It also contains retinol, which helps smooth the look of skin texture and even the look of skin tone while a blend of soothing ingredients helps balance the skin’s microbiome. This hydrating formula also contains sodium PCA and sodium hyaluronate, which moisturize skin and help offset dryness that could be caused by salicylic acid and/or retinol.

What you can do differently: Instead of dousing your zit with a spot treatment, apply a dab of OTC 1 percent hydrocortisone cream, like Aveeno One Percent Hydrocortisone Anti-Itch Cream, onto the spot two to three times during the day to take down the inflammation and redness. Then conceal it by simply covering it up with a concealer, like Clinique Even Better Compact Makeup, which has antibacterial ingredients to keep the formula bacteria-free and your face clear.
In the recent times, Vitamin E has been considerably recognized as one of the very beneficial vitamins for human skin. It can thoroughly moisturize your skin and in this process, it makes the scars or spots on your skin less noticeable. This is all because it hydrates your skin well with its moisturizing properties. There is one more theory regarding vitamin E and its effectiveness in reducing acne scars. This theory says that vitamin E assists vitamin A in your body. Vitamin A is thought to be vital for a good skin. When you have vitamin E, present in many fruits and vegetables, the fat in your body absorbs this vitamin E. It then works with vitamin A to give you soft, supple and blemish free skin. Deficiency of vitamin E can even lead to dry skin and acne breakouts. Therefore, it is always advisable to provide your body with sufficient vitamin E. Now the question arises, how to use vitamin E on acne scars! Here’s how to do so.

Scars are varied and complex, and learning how to get rid of acne marks requires trial and error. There are a variety of ways to get rid of acne scars and each corner has a different proponent. However, before you go jumping on the bandwagon for the latest cure-all, we suggest breaking down the various treatments methods into their disparate parts.
Take a fresh lemon and squeeze out its juice. Apply this juice directly on your scars with fingertips or a cotton ball, leave it for ten minutes and wash it off with water. Do this once a day for two to three weeks during which you can see your scars diminish considerably. If you want, you can also mix honey with your lemon juice to make it some more effective in reducing the acne scars.
Photodynamic therapy (PDT) is a procedure that treats precancerous cells, in addition to other types of cancer cells. The medical treatment does this with the help of a photosensitizing drug and a light source that activates the applied drug, destroying cancer cells. PDT is approved to treat non-small cell lung cancer, esophageal cancer, and Barrett's esophagus. It's used to treat actinic keratosis, as well as acne, rosacea, skin cancer, sun damage, oily skin, wrinkles, warts, psoriasis, and enlarged sebaceous glands.
