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.
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.
If you have scarring, your dermatologist may suggest surgery to help heal acne lesions and remove scarring. A laser can reshape scar tissue and reduce redness. Dermabrasion is a type of surgery that can remove surface scars and reduce the depth of deep scars. Another option is to transfer fat from one part of the body to the face. In some cases, a single treatment can help scarring. But for lasting results, several are often needed. There are also topical treatments for acne scarring.

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.
"Retinoids work over time by continuously increasing cell turnover which in turn helps fade hyperpigmentation," says Dr. Idriss. Dr. Shah agrees, noting that Retin-A helps with acne marks by causing your skin cells to "divide more rapidly and pushing out cells with discolored pigments." Since retinoids make your skin super-sensitive to the sun, it's best to not only wear SPF, but to also apply a treatment like RoC Retinol Correxion Sensitive Night Cream before you go to bed.
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.
True acne scars — as in indentations in the skin like ice-pick scars — can only be erased with professional procedures like microneedling or lasers. Fortunately, what most of us refer to as “scars,” according to Julia Tzu, M.D., founder and medical director of Wall Street Dermatology, are actually marks caused by post-inflammatory hyperpigmentation (brown spots) or post-inflammatory erythema (red spots), that will fade over several months or years. Fortunately, there are products that can speed up the process.
Apple cider vinegar has many properties. It is an astringent and a natural disinfectant that makes it a good natural antiseptic. It also balances the pH level of your body and of your skin when applied topically. And because it is anti-bacterial and anti-inflammatory, it is effective in the treatment of acne too. All of these properties of apple cider vinegar are granted by its beneficial components that include vitamins, minerals, carbolic acid, ketones, aldehydes, amino acids, anti-oxidant, acetic acid and many more. It is therefore a known remedy for acne. You can also heal acne scars considerably with apple cider vinegar. As this vinegar scrapes off the dead skin cells, it may fade away the acne scars to a great extent. You can either use apple cider vinegar with water or with honey.
Acne (acne vulgaris, common acne) is a disease of the hair follicles of the face, chest, and back that affects almost all teenagers during puberty -- the only exception being members of a few primitive Neolithic tribes living in isolation. It is not caused by bacteria, although bacteria play a role in its development. It is not unusual for some women to develop acne in their mid- to late-20s.
