You've probably seen those tiny glass jars filled with liquid and some solid sediment at the bottom—sometimes it's pink, sometimes it's white, and (in the case of my favorite product) sometimes it's flesh-tone. The solid in the jar is usually a mix of drying ingredient like camphor, sulfur, and zinc oxide, but many brands throw in a few little extras. Cult-favorite Mario Badescu Drying Lotion adds calming calamine and exfoliating salacylic acid to their formula, while my favorite, End-Zit Acne Control Drying Lotion, keeps it simple, but comes in several shades so that it conceals your breakout while it treats it.
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.
Eat healthily. Foods that are highly processed and contain a lot of oils greatly increase the amount of acne on your body. Getting the proper amount of nutrients from whole grains, fruits, vegetables, and protein help your skin to regenerate faster and limit unnecessary oil production. When at all possible, avoid foods that are processed or contain a lot of sugar (think junk foods).
Buying a generic face wash won’t necessarily improve your complexion; for a cleanser to be most effective, you have to pay attention to your skin’s needs and pick the ingredients accordingly. If your skin tends to be oily, choose products with salicylic acid, benzoyl peroxide, or glycolic acid. For sensitive skin, look for cleansers with lactic acid or hydrating ingredients like glycerin, which aren’t as drying as those made for oilier types.
Mix and match: "Since acne scars vary, so do treatments. Depending on the individual, I often use a multimodal approach to treating acne scars. First, I might use Fraxel treatments to smooth out the skin texture. Then, I often use a combination of the fillers Restylane and Belotero to lift the depressed scars. Finally, I perform a few punch excisions to surgically remove any deep scars that may remain," says Dr. Bowe. There are also topical treatment options for active breakouts that help prevent scarring, which can be used to get out ahead of things.
Dr. Shiel received a Bachelor of Science degree with honors from the University of Notre Dame. There he was involved in research in radiation biology and received the Huisking Scholarship. After graduating from St. Louis University School of Medicine, he completed his Internal Medicine residency and Rheumatology fellowship at the University of California, Irvine. He is board-certified in Internal Medicine and Rheumatology.
Steroid injections: If you feel a stress pimple rearing its ugly head, a steroid shot can be administered the same day you call your derm because the process is very fast. Not only does it immediately reduce the inflammation of an existing zit, but cortisone can also help thick scars (keloids) appear softer and flatter. "These are specifically for raised scars, however," says Dr. Shah. "It'll help flatten out the scar, but it won't do anything to any discrepancies in the texture."
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.
Many people also report a direct relation towards dairy consumption and acne, with many reporting a complete clear up after cutting dairy out of their diet. While it is an effective way to deal with the problem, your body does still require the nutrients from dairy to remain healthy, so if you do cut it out, make sure you find other sources for the nutrients, including a supplement.
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. 
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.
