In order to treat acne marks and scars, it's helpful to learn how to distinguish between the two. "What many people don’t realize is that a dark or pink mark on the skin is not actually an acne scar. Inflammation in the skin often leaves behind a stain as part of the natural healing process. The inflammation revs up pigment production, creating the mark that fades on its own over several weeks to months," says dermatologist and 2018 Acne Awards judge Dr. Joshua Zeichner. Unlike scars, these are smooth to the touch (AKA, not raised or indented), and signify that there is no permanent collagen damage to the skin.
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.
Severe acne. Severe acne consists of deep cysts, redness, swelling, extreme damage to the skin and scarring. You should see a dermatologist to care for this type of acne. Scarring can be prevented with appropriate treatments. Your dermatologist can prescribe oral antibiotics and oral contraceptives. Large inflamed cysts can be treated with an injection of a drug that lessens the redness, swelling, and irritation, and promotes healing.
A benzoyl peroxide cream (2.5 percent strength) is a good choice for adolescents experiencing red or inflamed breakouts that aren't getting better with medicated cleansers. Benzoyl peroxide is a very common and inexpensive acne treatment cream that can be found over-the-counter in the skin care aisle. Benzoyl peroxide kills the bacteria that cause pimples and is highly successful in treating mild cases of acne.
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 remedies benzoyl peroxide and salicylic acid are key ingredients in body washes designed to get rid of acne. Choose an oil-free body wash with acne medication like benzoyl peroxide or 2 percent salicylic acid. Apply the body wash to the affected areas and leave on for a minute or two to allow the acne medication to work its magic. Rinse well. Remember that products that contain benzoyl peroxide bleach fabric and may ruin towels, clothes and sheets/pillow cases. Change to white or something you don't mind bleaching.
The best way to fix them: Since they're more closely related to bacteria than your hormones or a lack of exfoliation, papular pustules require a different plan of attack entirely. "Inflammatory acne types really respond to antibiotics, either topical or systemic," says Dr. Hale. These, of course, require a trip to your dermatologist. To tide you over, you could also try applying hydrocortisone cream, which temporarily takes down redness and swelling. But in the long run, it won't do much to make these disappear completely or keep them from popping up again.
In dermatology, PDT with the photosensitizer Levulan Kerastick (20% delta-aminolevulinic acid HCl) is used for the treatment of very early, thin skin cancers called actinic keratoses (AK). The initial approval was specifically for the treatment of actinic keratosis of the face and scalp with a combination of an application of the photosensitizer followed by a timed exposure to a special blue light source. PDT is also used for acne, rosacea, skin cancer, sun damage, cosmetic skin improvement, oily skin, enlarged sebaceous glands, wrinkles, rejuvenation (anti-aging), warts, hidradenitis suppurativa, psoriasis, and many other skin conditions.
The nose is typically one of the first facial areas affected in rosacea. It can become red and bumpy and develop noticeable dilated small blood vessels. Left untreated, advanced stages of rosacea can cause a disfiguring nose condition called rhinophyma (ryno-fy-ma), literally growth of the nose, characterized by a bulbous, enlarged red nose and puffy cheeks (like the classic comedian W.C. Fields). There may also be thick bumps on the lower half of the nose and the nearby cheek areas. Rhinophyma occurs mainly in men. Severe rhinophyma can require surgical correction and repair.
12. Step away from your hands. You know how you rest your face on your hand while you're studying? That might be the reason for those blemishes on your cheek or jaw. You're constantly touching things that have germs—anything from your phone to your locker—so putting your hands on your face for a long period of time can cause dirt and bacteria from anything you touch to get into your pores.
Rosacea is a skin disease that causes redness of the forehead, chin, and lower half of the nose. In addition to inflammation of the facial skin, symptoms include dilation of the blood vessels and pimples (acne rosacea) in the middle third of the face. Oral and topical antibiotics are treatments for rosacea. If left untreated, rhinophyma (a disfiguring nose condition) may result.
