The earliest pathologic change is the formation of a plug (a microcomedone), which is driven primarily by excessive growth, reproduction, and accumulation of skin cells in the hair follicle. In normal skin, the skin cells that have died come up to the surface and exit the pore of the hair follicle. However, increased production of oily sebum in those with acne causes the dead skin cells to stick together. The accumulation of dead skin cell debris and oily sebum blocks the pore of the hair follicle, thus forming the microcomedone. This is further exacerbated by the biofilm created by C. acnes within the hair follicle. If the microcomedone is superficial within the hair follicle, the skin pigment melanin is exposed to air, resulting in its oxidation and dark appearance (known as a blackhead or open comedo). In contrast, if the microcomedone occurs deep within the hair follicle, this causes the formation of a whitehead (known as a closed comedo).
Acne mechanica is caused by heat, friction, and pressure against the skin, often the result of wearing sports gear such as a helmet or baseball cap. It is sometimes called "sports-induced acne" because it occurs frequently in athletes. Preventive measures include wearing an absorbent material under sports equipment and showering immediately after activity.
Salicylic acid is a topically applied beta-hydroxy acid that stops bacteria from reproducing and has keratolytic properties. It opens obstructed skin pores and promotes shedding of epithelial skin cells. Salicylic acid is known to be less effective than retinoid therapy. Dry skin is the most commonly seen side effect with topical application, though darkening of the skin has been observed in individuals with darker skin types.
How to Handle It: Think of these as bigger, pissed-off whiteheads. Your best bet, says Zeichner, is to stock up on benzoyl peroxide, which kills the bacteria. A spot treatment like Murad Acne Spot Fast Fix ($22) should do the trick. Also, try not to pop them — as tempting as that may be. Since they're inflamed, they're more likely to scar if you go the DIY route.

Baby acne almost always goes away on its own with no intervention. But bring it to your pediatrician's attention if the bumps look like they might be infected (for example, skin appears extra red, you notice swelling or discharge, or your child spikes a fever or has other symptoms) or if you suspect an allergic reaction or eczema (which may require a cream to keep the rash from spreading).
The relationship between diet and acne is unclear, as there is no high-quality evidence that establishes any definitive link between them. High-glycemic-load diets have been found to have different degrees of effect on acne severity. Multiple randomized controlled trials and nonrandomized studies have found a lower-glycemic-load diet to be effective in reducing acne. There is weak observational evidence suggesting that dairy milk consumption is positively associated with a higher frequency and severity of acne. Milk contains whey protein and hormones such as bovine IGF-1 and precursors of dihydrotestosterone. These components are hypothesized to promote the effects of insulin and IGF-1 and thereby increase the production of androgen hormones, sebum, and promote the formation of comedones. Available evidence does not support a link between eating chocolate or salt and acne severity. Chocolate does contain varying amounts of sugar, which can lead to a high glycemic load, and it can be made with or without milk. Few studies have examined the relationship between obesity and acne. Vitamin B12 may trigger skin outbreaks similar to acne (acneiform eruptions), or worsen existing acne, when taken in doses exceeding the recommended daily intake. Eating greasy foods does not increase acne nor make it worse.

Shower twice a day. Take a shower or bath in the morning and at night. Alternatively, take a shower in the morning and then again after physical activity, like exercise, or sweating. Wash your entire body with a mild cleanser and use shampoos that limit oil production in your hair. Be sure to always shower after exercising to remove the dead skin cells your body has sloughed off through sweating.
While you can certainly benefit from a great skin-care regimen, "in cystic acne, usually you need internal treatment," he says. "Topical medications usually don't work. Accutane is a great miracle cure for really bad cystic acne, but most people with cystic acne will improve with oral antibiotics — sometimes for two weeks, sometimes for three weeks."
A good way to lessen constant acne is to improve your lifestyle choices. Try to maintain a fresh and healthy diet, incorporating a lot of fresh fruits and nuts. Try your best to avoid dairy products and any packaged foods. The more fresh the food is, the better it is for your skin. Exercise is also a vital component in the maintenance of healthy skin. Try to complete some form of cardio for at least 30 minutes a day, 3-4 times a week. If none of this is successful, consider consulting a dermatologist.
Alternative and integrative medicine approaches used in the treatment of acne include fish oil, brewer's yeast, probiotics, oral zinc and topical tea tree oil. More research is needed to establish the potential effectiveness and long-term safety of these and other integrative approaches, such as biofeedback and traditional Chinese medicine. Talk with your doctor about the pros and cons of specific treatments before you try them.
