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.
Those who consume a bevy of seafood, seaweed, and iodized salt experience high iodine levels. These iodine levels have also been purported to trigger acne flare ups. Word spread about iodine’s potential for causing skin issues in the 1960s, and it’s had a bad rap ever since. However, recent studies have fought against this pervasive thought, as some studies have seen no difference between acne in those who were given iodine and those who weren’t. It’s important to take these studies with a grain of salt, and understand that depleting your diet of iodine can have negative effects on holistic health. Iodine is essential for proper thyroid function, and is responsible for the manufacture of T3 and T4 thyroid hormones and it’s important to maintain proper levels of iodine in your diet.
Acne scars, on the other hand, are formed when there is damage to the skin which leads to abnormal collagen production, and usually appear raised or bumpy. "There are two types of acne scars: depressed and raised. Depressed scars may look like pits or craters, and raised scars may be firm and tender," explains Dr. Zeichner, who notes that unfortunately, these are permanent.
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.
9. You're not releasing pent-up stress properly. Stress triggers acne and acne results in more stress, so it's a very vicious cycle. Basically, when you're under pressure, your skin produces stress hormones, including cortisol, that can stimulate your oil glands to make testosterone that then increases oil production and clogs pores.

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. 
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.
Understanding why you break out requires consideration of a variety of aspects. There are many underlying reasons for acne breakouts, but most pimples are caused by fluctuations in hormone levels. During puberty, the increase in androgens (male hormones) causes the adrenal glands to go into overdrive. This triggers the production of sebum within the sebaceous glands. The more sebum produced, the easier it is for hair follicles to become clogged. When the follicle becomes blocked, oil can’t leave the pore, collecting dead skin cells that would have otherwise sloughed off and hanging onto bacteria called p. acnes. These hormonal fluctuations can arise at other times in life, including menstruation, pregnancy, and menopause.
"I have seen many patients develop a tolerance to prescription acne treatments, and when they stop working, it’s devastating. Treating acne demands a more holistic approach that includes lifestyle, nutrition, and advances in topical skincare. I developed Outsmart Acne™ Clarifying Treatment to be used as part of a whole-person regimen to help skin stay consistently clear."Howard Murad, M.D., FAAD
Treat Acne As Soon As It Develops: The best thing you can do is get acne under control as soon as possible. Begin treating it right away, and see your doctor immediately if your acne isn't getting any better with over-the-counter acne treatments. Quick treatment helps to keep breakouts to a minimum and prevents acne from developing into a more severe form. Prevent pimples and you'll prevent scarring.

Lasers: Dermatologists often remodel collagen using lasers, "which do not completely eliminate acne scars but can improve them by 30% or more," according to Dr. Woolery-Lloyd. "These can be helpful in reducing the redness associated with acne marks and scars. I use a pulse-dye laser called the V-Beam for red scars. When treating older scars that are no longer red, I like to use the Fraxel laser. When lasers are used to treat acne scars, the results can differ dramatically based on two things: how many treatments you have done, and how much social downtime you're willing to accept as part of the recovery process," says Dr. Bowe. "Erbium laser resurfacing is also another option and it's more aggressive than Fraxel," says Dr. Shah. "It's a minimal burning of surrounding tissues and has fewer side effects like less swelling and redness, but it's won't work for those with darker skin tones."
No one factor causes acne. Acne occurs when sebaceous (oil) glands attached to the hair follicles are stimulated at the time of puberty or due to other hormonal changes. Sebum (oil) is a natural substance that lubricates and protects the skin. Associated with increased oil production is a change in the manner in which the skin cells mature, predisposing them to plug the follicular pore. The plug can appear as a whitehead if it is covered by a thin layer of skin, or if exposed to the air, the darker exposed portion of the plug is called a "blackhead." The plugged hair follicle gradually enlarges, producing a bump. As the follicle enlarges, the wall may rupture, allowing irritating substances and normal skin bacteria access into the deeper layers of the skin, ultimately producing inflammation. Inflammation near the skin's surface produces a pustule; deeper inflammation results in a papule (pimple); if the inflammation is deeper still, it forms a cyst.
