Avoid creams with vitamin E. Creams with vitamin E may actually do more harm than good. Because it's a vitamin, we're tempted to think that it will be either beneficial or harmless. In fact, one University of Miami study reported that vitamin E treatment had no effect or worsened the appearance of scars in 90% of subjects, with improvement in only 10% of cases.
"I often recommend PCA Skin Pigment Gel to patients looking to treat scars left behind from acne," explains Rebecca Kazin, a dermatologist at Washington Institute of Dermatologic Laser Surgery and Johns Hopkins department of dermatology. "This gel contains 2 percent hydroquinone blended with other skin brighteners, like kojic acid, resorcinol, and azeleic acid, which work to lighten the pigmentation without irritating the skin," she says. The addition of lactic acid helps maintain moisture to prevent overdrying, which can worsen pigmentation.
Have good hygiene. There is a balance between under-washing and over-washing skin. Under-washing leaves excess skin cells, oil, bacteria, and other debris on the skin, potentially clogging pores and creating blemishes. Over-washing irritates and dries the skin, contributing to excess oil production and more breakouts. Refrain from washing problem areas more than twice a day. When washing, use gentle cleansers with smooth grains and light scrubbing to exfoliate. Avoid products containing large grains, such as almond or apricot shell fragments, that will potentially damage or irritate the skin.
Consider exfoliating with baking soda. Baking soda can be used to exfoliate the skin and minimize the appearance of acne scars. All you need to do is mix one teaspoon of baking soda with two teaspoons of water to form a liquid paste. Apply this paste all over your face and use gentle circular motions to rub the baking soda into the skin, concentrating on the scarred areas, for about two minutes. Rinse off with warm water and pat the skin dry. 
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.
Yes, it’s another pricey SkinCeuticals serum, but dermatologists absolutely love their products for treating acne marks. You’ll get more bang for your buck with the inclusion of glycolic and lactic acids, two alpha-hydroxy acids that Avram says help fade marks by exfoliating the top surface of the skin. Nagler says “vitamin C is helpful as an adjunct in preventing free radical damage, which helps with pigmentation.” It’s also worth investing in a high-quality serum since, according to Nagler, vitamin C isn’t stable — and is therefore less effective — in some other products.
Use oil-free makeup. If you wear makeup, you may be stuck in a vicious cycle of covering up acne while simultaneously causing it with your cover-up usage. Find acne-fighting oil-free mineral makeup to help prevent worsening your acne while simply trying to hide it. Power foundations are also recommended. When possible, avoid wearing make-up at all though as it clogs your pores over the course of the day.

Instead, you’ll want to talk to your dermatologist about what can be done about your scarring. There are professional procedures that can smooth the skin and minimize scars. Laser treatments are often used to treat acne scars. Your dermatologist might also suggest dermal fillers to “plump up” the depressed area leaving the skin, albeit temporarily, more smooth and even.
Keloid bumps are generally discolored and raised. These scars form when the body tries to recover from the inflammation caused by cystic acne. According to Dr. Sobel, you can get a keloid if too many fibroblasts or dermal cells are produced during the healing process. The first step in treatment is to flatten the bump with a shot of cortisone. Then, you can follow up with other treatments like laser or retinol to even out the skin tone.
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.
Acne scars are most often the product of an inflamed lesion, such as a papule, pustule, or cyst. Inflamed blemishes occur when the follicle, or pore, becomes engorged with excess oil, dead skin cells, and bacteria. The pore swells, causing a break in the follicle wall. If the rupture occurs near the skin's surface, the lesion is usually minor and heals quickly. More serious lesions arise when there is a deep break in the follicle wall. The infected material spills out into the dermis and destroys healthy skin tissue.
Consider cosmetic surgery. As a last resort, consult with a medical professional about surgery for large, deep lesions or scars. In this procedure, a doctor will use a punch excision to cut out the scar and replace it with stitching or a skin graft. Smaller lesions require only stitching, while large lesions may require a skin graft from another part of your body.
Medications prescribed for mental illnesses can have the unfortunate side effect of causing acne. Some antidepressants have been purported to trigger acne breakouts, including brands like Wellbutrin and Lexapro. Those diagnosed with bipolar disorder are often prescribed lithium to help handle their condition. Unfortunately, lithium can cause acne breakouts. Often the benefits of these types of drugs outweigh the negative onset of acne, but it’s important to look into various options to determine what might have the minimal amount of side effects.
However, if you have a scar, you’re dealing with permanent skin damage that needs treatment in order to disappear. An acne scar changes the texture of the skin. If acne has left indentations, or raised spots, the damage has occurred at a deeper level in the skin. This “cobblestoning” effect indicates scarring that needs more than a surface-level treatment.
Other concerns include inflammatory bowel disease and the risk of depression and suicide in patients taking isotretinoin. Recent evidence seems to indicate that these problems are exceedingly rare. Government oversight has resulted in a highly publicized and very burdensome national registration system for those taking the drug. This has reinforced concerns in many patients and their families have that isotretinoin is dangerous. In fact, large-scale studies so far have shown no convincing evidence of increased risk for those taking isotretinoin compared with the general population. It is important for those taking this drug to report changes in mood or bowel habits (or any other symptoms) to their doctors. Even patients who are being treated for depression are not barred from taking isotretinoin, whose striking success often improves the mood and outlook of patients with severe disease.
